EXECUTIVE SUMMARY
The Environmental Protection Agency (EPA) is studying the issue of heavy metals and
other non-nutritive constituents (also referred to as contaminants) in fertilizers and liming
materials (referred to as fertilizers hereafter). The purpose of this report is to provide background
information on fertilizer use, consumption patterns, composition and regulations. This
information is gathered and presented here for fertilizers from natural mineral sources and those
that are derived from industrial by-products. The data for heavy metals in fertilizers compiled
here are used to provide estimates of the rates at which these metals may be added to agricultural
soils from standard agronomic practices. The additions of heavy metals to agricultural soil are
discussed in terms of federal and international regulations.
This report is provided as a source of information. It is not intended as a risk-assessment
for contaminants in fertilizer, nor does it address the introduction of these materials into plants,
the food chain for humans, and the greater ecosystem. Although some discussion is given here to
biosolids (sewage sludge) and its regulations, and other organic fertilizers, such information is
limited. The focus of this report is on inorganic fertilizers and their application to agricultural
lands. Discussion related to fertilizer usage on public lands, range lands, and residential lawns
and gardens is limited for this reason. In addition, some information is presented on the use of
recycled industrial by-products as fertilizers; however, an in-depth investigation of these
recycling practices was beyond the scope of this study.
More than 54 million tons (110 billion pounds) of commercial fertilizers and liming
materials of all kinds were consumed in the United States in the year ending June 30,1996
(AAPFCO, 1997a). Primary nutrients (N, P, K) accounted for 91% of this total; Inning materials
accounted for about 4%, and organic fertilizers accounted for 1% of the total. Approximately 5%
of the total (2.7 million tons) was due to secondary nutrient fertilizers (calcium, magnesium,
sulfur) and micronutrients. States with the highest fertilizer consumption were the agricultural
states in the com belt and California. Florida (1.6 million tons) and Texas (1.6 million tons)
consumed the most multiple nutrient fertilizers while Illinois (1.9 million tons of nitrogen (N),
0.8 million tons of phosphate (P2O5) and 1.0 million tons of potash (K2O),fertilizers) consumed
the most single-nutrient N, P, and K fertilizers. North Carolina consumed most of the organic
fertilizers and liming materials (0.2 million tons organic fertilizer, 0. 9 million tons liming
fertilizer), while California consumed most of the secondary and micronutrient fertilizers (1.6
million tons).
The potato crop was the most fertilized (100% of acres receive N, P and K fertilizers) and
had one of the highest fertilizer application rates for all primary nutrient fertilizers (average
application rates of 195 Ibs/acre N, 173 Ibs per acre P2O5 and 139 Ibs/acre K2O) but represented
fewer acres planted (0.8 million acres) than other field crops except tobacco. If consideration
were given to the number of acres planted, com (70 million acres) represented the crop with the
highest fertilizer use, though not the highest application rate per acre (average application rates of
133 Ibs/acre N, 57 Ibs/acre P2O5 and 79 Ibs/acre K2O). The fruits and vegetables with the highest
fertilizer application rates were watermelon in Arizona (N), bell peppers in California (P2O5) and
fresh tomatoes in Florida (K2O). The two states with the highest total consumption of non-farm
fertilizer were Florida (0.4 million tons) and California (0.32 million tons). Multiple nutrient,
organic and miscellaneous fertilizers were used in higher percentages on non-farm land than
-------
other fertilizers. Non-farm fertilizer use included applications to residential, recreational and
public property.
Soils naturally contain trace levels (ppb to ppm) of heavy metals. For example, median
concentrations of metals in U.S. soils are 0.2 mg/kg cadmium, 11 mg/kg lead, and 18.2 mg/kg
nickel. There are, however, considerable variations in these metal concentrations by geographic
region and soil type.
Several studies have measured heavy metals in mineral ores and the resulting fertilizers.
Natural rock phosphate ore contains zinc ranging from 0.2 to 576 mg/kg and measurable
amounts of cadmium, lead, nickel and copper. These metals can also be found in the NPK
fertilizers that are produced from natural ores. For example, the State of Washington Department
of Ecology reports the ranges of metal concentrations for a sample of 21 diverse NPK fertilizers
with cadmium levels being <0.1-145 mg/kg, lead levels being O.4-21 mg/kg, and nickel levels
being O.2-195 mg/kg. Measurements of other NPK fertilizers by other authors generally fall
within this same range of values. A few studies have also measured arsenic, chromium and
mercury in NPK fertilizers.
Organic and biosolid fertilizers may also have measurable concentrations of heavy
metals. One study of 6 organic fertilizers (Raven and Loeppert;1997) reported measureable
levels for heavy metals such as arsenic, cadmium, chromium, lead and mercury. According to
these authors, "Trace metal concentrations generally decreased in the following sample order:
rock phosphate > sewage sludge > commercial phosphate fertilizers > organic amendments and
liming materials > commercial K2O fertilizers > commercial N fertilizers". Whether or not
fertilizers add significant amounts of metals to soil depends upon several factors including the
existing soil metal concentration, the concentration of trace metals in the fertilizer and the
fertilizer application rate.
Since some industrial wastes contain substances which can be used, or converted for use,
in fertilizers, industrial waste recycling is encouraged in the U.S., if done so in a safe manner.
The concern is that the wastes may also contain potentially hazardous constituents that provide
no nutritive value to the plant and introduce these constituents into the greater ecosystem. No
specific regulations exist requiring fertilizer producers to list non-nutritive constituents on
fertilizer labels, so it is difficult to quickly ascertain the levels of heavy metals (and other
chemicals) in fertilizers. Chemicals such as radionuclides and persistent organics (e.g.,
chlorinated dibenzodioxms/furans) are in this category. Several studies have shown that heavy
metals are present in the parts per million (mg/kg) range, and occasionally as high as parts per
thousand, in fertilizers produced from recycled industrial by-products.
Industrial wastes may be used in the manufacture of fertilizers, provided that such use
constitutes legitimate beneficial recycling, and that the concentrations of hazardous constituents
in the resulting fertilizers do not exceed the treatment standards specified for the wastes (40 CFR
266.20). No other federal standards apply specifically to fertilizer composition. State
regulations require nutrient composition labeling of fertilizers.
Most states regulate fertilizer composition, but generally only for the plant nutrients.
State fertilizer laws generally require product registration and/or licensing and efficacy testing to
-------
assure that statements made on the label are correct. Most fertilizer regulations also include
general statements about product adulteration and a prohibition against including any product
that is harmful to plants, animals, humans or the environment. At this time, only two states
(Washington and Texas) have regulations that establish specific limits on heavy metal
contaminants, and testing and labeling requirements.
RCRA regulations generally encourage waste minimization and recycling. Examples of
hazardous wastes that can be recycled into fertilizer ingredients (usually micronutrient fertilizers)
include wood ash, K061 wastes (emission control dust/sludge from the primary production of
steel in electrical furnaces), brass foundry dusts and tire ash. The Occupational Safety and
Health Administration (OSHA) in its hazard communication standard requires employers to
include in Material Safety Data Sheets (MSDS) information on any product component present
at 1% or greater (0.1% for carcinogens). Thus, if certain metals are present in sufficient quantity
in fertilizer products, there exists a mechanism for communicating information on hazardous
metal content.
Internationally, the Canadian Fertilizers Act (1993) and Fertilizers Regulations contain
specific limits for heavy metals that apply to all fertilizer products. The Canadian Food
Inspection Agency originally developed these limits for biosolids applied to land, but these
standards now apply to all fertilizers. The Canadian standards are not risk-based, but were
instead developed with the objective of "no significant degradation" of soils above background
concentrations of metals. Japan regulates industrial waste incinerator ash application to land and
has limits for metals and organic chemicals. Additionally, Australia and several European
countries limit cadmium in phosphate fertilizers.
The U.S. EPA, states and foreign countries regulate biosolids application to land. The
U.S. EPA (40 CFR 503) sets limits for heavy metals in biosolids hi the product and on the soil
following application. Several states have more stringent metal limits for biosolids application to
land. Many foreign countries also have limits for heavy metals in biosolids and for soil. The
European Union (EU) has set standards for its member countries, but individual countries may
have more stringent regulations. The EU biosolids standards, in units of mg/kg of sludge
product, are generally lower than those of the U.S. ceiling concentrations for land applications
but are similar to the U.S. monthly average concentrations for application to agricultural land.
This report includes a characterization of the addition of heavy metals to agricultural soils
from application of fertilizers which contain heavy metals. The calculations used here are
designed to provide an estimate of the yearly incremental additions of metals to soils following
diverse types of fertilizer applications. These incremental increases are then used to estimate the
years required to double average background levels of metals in soil from yearly applications.
These yearly additions of metals to the soil are then compared to the U.S. biosolids annual
pollutant loading rates and the Canadian Fertilizers Act limits.
Fertilizer products are compared in this report with respect to the amount of nine heavy
metals the product would add to soil, assuming a single application of the product per year. This
is termed the yearly soil addition rate of a metal (or "yearly addition of metal X", see Index of
Terms). The yearly soil addition rate of a metal is the concentration of that heavy metal in the
product per desired nutrient ingredient multiplied by the nutrient application rate, with all
-------
appropriate conversion factors applied. For those fertilizer products with lower nutrient content, a
proportionally greater amount of the undesirable heavy metal will be added to the land in
achieving a consistent nutrient application rate. Therefore, a fertilizer product may contribute
high levels of heavy metals to soil when the heavy metal concentration in the product is high
and/or when the desired plant nutrient is at a low level in the product.
For this report, the yearly addition of each metal was calculated for each individual
product at three nutrient application rates- an average nutrient application rate, a high rate and at
the maximum application rate recorded for this nutrient. An extended appendix of this report
(Appendix G) contains the yearly soil addition rate of each metal in each product when applied at
these three nutrient application rates. The aggregate of these individual yearly addition rates,
then, produced the average soil metal addition rate for a fertilizer product category (e.g., P2O5
fertilizers) at the three different nutrient application rates. This aggregate is termed the product
average yearly addition of metal X (see Index of Terms). This summary includes discussions of
the yearly addition of metals in terms of both the individual product giving the highest yearly soil
addition of a specific metal, and in terms of the product average yearly addition rates for metals.
The calculations performed here showed that the product average yearly addition rates of
metals to soil would not exceed the U.S. biosolids annual pollutant loading rates for any fertilizer
category evaluated. This finding applied to both natural ore-derived fertilizers and industrial by-
product derived fertilizers.
The calculations also showed that the product average yearly addition rates of metals to
soil rarely exceeded the annualized Canadian Fertilizers Act limits for metals additions. The
particular instances when the product average addition rate of metal to soil exceeded the
Canadian limits were found in the following combinations of heavy metal and fertilizer
categories, and this occurred only at the maximum nutrient application rate:
Arsenic in: liming materials (CaCO3 applied at 15,000 Ibs/acre once every 3 years)
iron fertilizers (iron applied at 30 Ibs/acre every year)
The Canadian standards for metals additions to soil were exceeded more frequently for
individual fertilizer products, and were exceeded for metals other than arsenic. A total of 38
cases were identified where a particular heavy metal in an identified individual fertilizer product
would exceed Canadian fertilizer standards when applied at the maximum nutrient application
rate. These cases included:
Cadmium in: NPK fertilizers applied for P2O5 content [10 products of 91 evaluated
exceeded limits; 10 of 91]
Phosphate fertilizers [1 of 61]
Liming materials [3 of 10]
Zinc fertilizers [3 of 22]
Lead in : NPK fertilizers applied for P2O5 content [4 of 91]
Liming materials [2 of 10]
Zinc fertilizers [6 of 63]
Iron fertilizers [1 of 3]
IV
-------
Arsenic in: NPK fertilizers applied for P2O5 content [1 of 84]
Liming materials [3 of 10]
Iron fertilizers [1 of 3]
Mercury in: Liming materials [1 of 8]
Nickel in: Liming materials [1 of 8]
Zinc in: NPK fertilizers applied for N content [1 of 49]
Of the products listed above, 18 exceeded Canadian standards at the high nutrient
application rate, and 8 exceeded the standards at the average nutrient application rate. Data were
gathered here on 345 fertilizer products. A total of 1389 combinations of fertilizer product and
metal at three application rates (total of 4167 data points) were compared with Canadian
standards. (Data on an additional 537 combinations of unregulated heavy metals in products were
also gathered). Since some products exceeded standards in more than one metal, the number of
individual products exceeding the standards for at least one metal is greater than 2.7% (38 of
1389), but less than 11% (38 of 345).
Figure ES-1 identifies those fertilizer categories where the product average yearly
addition rate of a metal is likely to double the average level of that metal in background US soils
in 45 or fewer years, when the nutrient is applied at either the average (open box) or maximum
(closed box) application rate. Similarly, this figure also identifies those instances where at least
one individual product within a category exists that may double the average background level in
45 or fewer years, when the nutrient is applied at either the average (open circle) or maximum
(closed circle) application rate. These scenarios assume yearly applications, with exception of
lime, which is applied once every three years. For example, the product average application rate
of cadmium (Cd) from either NPK-P fertilizers (NPK fertilzers applied for P2O5 content) or from
P2OS fertilizers will double the average background Cd soil level in 45 or fewer years when either
the average or maximum nutrient (P2O5) application rate is used every year. In addition, there
were individual NPK-N, NPK-P and P2O5 products identified that would double background soil
Cd levels in 45 or fewer years if applied each year. There were no potash (K2O), gypsum,
manganese (Mn), or boron (B) fertilizer products identified that would double the indicated soil
metals levels in 45 or fewer years. In contrast, liming materials were identified that might double
the soil levels of all nine metals with consistent use (application once every three years) within a
45 year tune frame.
In the process of preparing this report, and performing the above mentioned calculations,
it was necessary to make a number of assumptions and simplifications to arrive at the
contaminant levels in the soil following fertilizer application.
The simplifying assumptions that were made, and implications thereof, include:
• Metal additions to the soil were based on application of a single fertilizer type, and a
single crop per year. In fact, many different fertilizers and liming materials may be

applied to a field in a growing season. The concomitant addition of heavy metals
from all sources was not assessed here.
To simplify calculations, soil type and chemical nature, plant uptake, leaching and
erosion and other removal mechanisms were not considered in these calculations. All
input of heavy metals was assumed to remain with the soil, and is therefore presumed
to be an overestimate of soil metals levels over a long time period.
Calculations of heavy metal additions to soil from fertilizers were based on all
available data. The representativeness of this data set with respect to all fertilizers is
not known. There has been as yet no systematic investigation of all fertilizer types,
or an investigation of the percentage of recycled industrial waste products with
substantial levels of heavy metals in the fertilizer market.
Fertilizer application rates for agricultural crops were the only ones considered here.
No attempt was made to capture the metals additions to residential and public lands,
because of a lack of information on application rates. Preliminary data on heavy
metals in home garden fertilizers suggest that significant amounts of metals may be
added to home gardens from use of some of these products.
In only a few instances was the origin (e.g., natural ore or industrial by-product) of
the fertilizer product known. Although it may be instructive to compare heavy metal
additions to soil from natural ores and products from industrial waste, such an
exercise could not be undertaken on the basis of the available data.
While the following list is not inclusive, some of the data gaps that may require further
study include:
• Nationally-representative micronutrient application rates. Aggregate average
application rates for micronutrients and liming materials by state, treated acres and
crop type have not been assembled, as has been done for N, P and K fertilizer.
• Regional variability in concomitant use of NPK, micronutrient and liming materials
on the same field. Statewide use data for each fertilizer type are available, but the
overlap in application by crop has not been compiled. Some areas of the U.S. may
receive higher input of heavy metals from fertilizers due to the combination of crop
type and existing soil conditions.
• Contribution of fertilizer products derived from industrial wastes to total fertilizer
market. While sources of most industrial waste-derived fertilizers are fairly well
known, the market share of these products in the total fertilizer market is not known.
• Statistically valid, nationally representative metal contaminant levels of all fertilizer
types. While researchers have measured contaminant levels in fertilizers, these
studies tend to represent either a single product type and/or products found in a
specific state.
VII
-------
Levels of other contaminants such as radionuclides and persistent organic chemicals
in fertilizers and liming materials. Compared with the data on heavy metals in
fertilizers, relatively little information exists on the levels of organic pollutants in
fertilizers. Such organics could include dioxins, PCBs, pesticides and PAHs.
The environmental fate of chemical additions to soil. This issue has been studied
primarily for cadmium and lead, and most often under controlled laboratory or field
conditions. All potential contaminants, soil types and crops have not been addressed.
In addition, the fate of metals added to the soil as a result of fertilizer addition to non-
agricultural land (e.g., range land and residential land) has not been adequately
studied.

Index of Terms
Cement Kiln Dust (CKD) - A by-product from the manufacturing of cement. Contains 4% to
12.8% of potash (K2O) and averages 30% Ca. Used primarily as a liming material. High content
of calcium oxide produces equilibrium pH in suspension of about 12. (Source: Fertilizer
Dictionary, Farm Chemicals Handbook).
Contaminant- A constituent or component of a fertilizer that is not part of the guaranteed analysis
and/or 1) is not a macronutrient (primary or secondary), 2) is not a micronutrient, 3) is not
required for plant nutrition (e.g., Cd, Pb, As, Hg, radionuclides, dioxins), and 4) may be essential
for some plants (and humans) at low levels or in one oxidation state but toxic at higher levels or
in a different oxidation state (e.g., Cr, Ni, V, Cu, Zn). Contaminant constituents are present
naturally in inorganic fertilizer ores and in industrial by-products reprocessed for fertilizers.
Diammonium Phosphate (DAP) - A type of NPK fertilizer. The fertilizer grade of DAP
(NH4)2HPO4 is made from wet-process phosphoric acid and ammonia and has a grade of 18-46-0.
DAP has an economic advantage over monoammonium phosphate (MAP) because the same
amount of acid reacts with twice as much ammonia. Substantial quantities of crystalline DAP
are produced as by-products from the iron and steel industry (Source: Fertilizer Dictionary, Farm
Chemicals Handbook).
Fertilizer - A substance that contains one or more recognized plant nutrients that is specially
designed to be used for its plant nutrient content and is claimed to promote plant growth. A
fertilizer material is a fertilizer which either:
A. Contains important quantities of no more than one of the primary plant nutrients:
nitrogen (N), phosphorus (P), and potassium (K), or
B. Has 85% or more of its plant nutrient content present in the form of a single chemical
compound, or
C. Is derived from a plant or animal residue or by-product or natural material deposit
which has been processed in such a way that its content of plant nutrients has not been
materially changed except by purification and concentration (Source: Fertilizer
Dictionary, Farm Chemicals Handbook).
Filler - A substance added to fertilizer materials to provide bulk, prevent caking, or serve some
purpose other than providing essential plant nutrients. (Source-Fertilizer Dictionary, Farm
Chemicals Handbook '97)
Guaranteed Analysis - The minimum percentage of plant nutrients claimed in a fertilizer that is
found on the fertilizer label (Source: Fertilizer Dictionary, Farm Chemicals Handbook).
Gypsum - A product consisting chiefly of calcium sulfate with combined water (CaSCy2H2O)
and is incapable of neutralizing soil acidity. Occurs in large deposits of soft crystalline rock and
as sand. A granulated form has been developed for application to soil (for growing peanuts and
XIII
-------
other crops) as a calcium source or sulfur source either by itself or in a blend of other fertilizers.
In irrigated agriculture it is used to increase permeability of soils (Source: Fertilizer Dictionary,
Farm Chemicals Handbook).
Heavy Metals - Certain metals, such as arsenic, cadmium, lead, mercury, and nickel, may be
present in varying concentrations in naturally occurring ores or in industrial by-products which
contain plant nutrients and are processed for fertilizers (Source: Fertilizer Dictionary, Farm
Chemicals Handbook).
Industrial By-Product - Waste materials from various industrial processes which contain plant
nutrients. These products may be converted into fertilizer materials, depending upon their
physical condition and on their content of possibly undesirable contaminants. Some by-products
are hazardous waste, others are not. (Source: Fertilizer Dictionary, Farm Chemicals Handbook).
Inorganic Fertilizer - A fertilizer material which does not have carbon as the essential component
of its basic chemical structure (Source: Fertilizer Dictionary, Farm Chemicals Handbook).
KjO- Potash or potassium oxide. Not used as a fertilizer per se, but the chemical term used as
the basic measure of potassium (K.) content in diverse potassium fertilizers such as potassium
chloride, potassium sulfate, potassium nitrate and potassium thiosulfate.
K061 Waste - Emission control dust/sludge from the primary production of steel in electric
furnaces (Source: Fertilizer Dictionary, Farm Chemicals Handbook).
Liming Materials - A product whose calcium and magnesium compounds are capable of
neutralizing soil acidity (Source: Fertilizer Dictionary, Farm Chemicals Handbook).
Macronutrients - Nutrients that plants require for growth in relatively large amounts. Includes
both primary and secondary nutrients. Primary nutrients are nitrogen, phosphorus, and
potassium. Secondary nutrients are calcium, magnesium, and sulfur (Source: Fertilizer
Dictionary, Farm Chemicals Handbook).
Micronutrients - Nutrients essential for normal growth of plants that are required relatively small
amounts. Micronutrients include boron, chlorine, cobalt, copper, iron, manganese, molybdenum,
sodium and zinc. (Source: Fertilizer Dictionary, Farm Chemicals Handbook).
Monoammonium Phosphate (MAP) - An important NPK fertilizer (NH4H2PO4) whose
production and use has increased steadily over the past several years. Granular product, made
with wet-process acid, has a grade of about 10-53-0. Some by-product MAP made with furnace
acid has a grade of 12-61-0 and is used mainly in production of liquid fertilizers. Nongranular
(powder) MAP is used in formulations for granular NP and NPK fertilizers, which it can react
with additional ammonia and aid granulation (Source: Fertilizer Dictionary, Farm Chemicals
Handbook).
Muriate of Potash (MP) - A potash salt containing 48% to 62% soluble potash (K2O), chiefly as
chloride. Also known as commercial potassium chloride (Source: Fertilizer Dictionary, Farm
Chemicals Handbook).
XIV
-------
N- Nitrogen, essential element for plant growth. Not used as a fertilizer per se, but the chemical
term used as the basic measure of nitrogen content in diverse fertilizers such as nitrates,
ammonium salts, liquid ammonium, urea, and natural organics.
Organic Fertilizer - A material that contains carbon and one or more elements besides hydrogen
and oxygen that are required for plant growth (Source: Fertilizer Dictionary, Farm Chemicals
Handbook).
P2O5- Phosphorus oxide. Not used as a fertilizer per se, but the chemical term used as the basic
measure of phosphorus (P) content in diverse phosphate fertilizers such as calcium phosphates,
ammonium phosphates, polyphosphates and superphosphates.
Phosphogypsum - Calcium sulfate (CaSCy2H2O) that is the dried by-product from the
manufacturing of phosphoric acid, see gypsum. (Source: Fertilizer Dictionary, Farm Chemicals
Handbook).
ppb- parts per billion. Unit of concentration equal to ng/g or ug/kg.
ppm- parts per million. Unit of concentration equal to ug/g or mg/kg.
Product Average Yearly Addition: Also product average yearly addition of metal X (e.g., Cd);
product average yearly soil addition rate of metal X. The average amount of metal X that will be
added to agricultural soil from all products of a specific fertilizer category. The product average
yearly addition is obtained by calculation: the sum of the yearly addition rates of metal X in
product type Y (e.g., P2O5 fertilizers) at nutrient application rate Z (e.g., average nutrient
application rate), divided by the number of products of that category evaluated. Product average
yearly addition is determined for three different nutrient application rates- average, high and
maximum.
Soil Amendments - Any substance that is added to soil (other than the substances used primarily
as fertilizer) that is thought to improve the physical characteristics of the soil, such as porosity to
water and air. Soil amendments do not include commerical fertilizers, agricultuural liming
materials, unmanipulated animal manures, unmanipulated vegetable manures, pesticides, and
other materials exempted by regulation but can contain important fertilizer elements (Source:
Fertilizer Dictionary, Farm Chemicals Handbook).
Yearly Addition: Also yearly addition of metal X (e.g., Cd); yearly soil addition rate of metal X.
The amount of metal X that is added to agricultural soil from the application of a specific
fertilizer product. Assumes one application of the product fertilizer in the year. The yearly
addition value is obtained by calculation as follows: the concentration of that specific heavy
metal in the fertiizer product per desired nutrient ingredient, multiplied by the nutrient
application rate, with all appropriate conversion factors applied. Yearly addition is calculated
with three different nutrient application rates- average, high and maximum.

BACKGROUND REPORT ON FERTILIZER
USE, CONTAMINANTS AND REGULATIONS
1.0 INTRODUCTION
The Environmental Protection Agency (EPA) is studying the issue of heavy metals and
other non-nutritive constituents (also referred to as contaminants) in fertilizers and liming
materials. The purpose of this report is to provide background information on fertilizer use,
consumption patterns, composition and regulations. This information is gathered and presented
here for fertilizers from natural mineral sources and those that are derived from industrial by-
products. The data for heavy metals in fertilizers compiled here are used to provide estimate of
the rates at which these metals may be added to agricultural soils from standard agronomic
practices. The addition of heavy metals to agricultural soil are discussed in terms of federal and
international regulations.
Some industrial by-products contain chemicals which provide plant nutrients. The
recycling of these materials conserves resources and minimizes waste, but at the same time may
result in fertilizer products that contain chemicals unnecessary for plant growth and
development. Examples of such chemicals are heavy metals such as lead and cadmium,
radionuclides chemicals and persistent organics such as chlorinated dioxins. Concern has been
raised that potentially hazardous constituents of recycled wastes, as well as naturally occurring
heavy metals in ores used for fertilizers, might be taken up by plants and ingested by humans or
animals in quantities that could be harmful to health. Additional concerns about use of fertilizer
products include risks to farmers and their families, damage to soil fertility, and dispersion into
groundwater and air.
States regulate label statements made about the plant nutrients (macronutrients: nitrogen,
phosphate, potash; secondary nutrients and micronutrients) in fertilizers, but, in general, do not
regulate other constituents that may be present as a result of the preparation of these products.
Existing EPA Resource Conservation and Recovery Act (RCRA) regulations allow with certain
restrictions the recycling of industrial wastes in the interest of minimizing waste that would
ultimately end up hi landfills or require additional treatment. EPA and the U.S. Department of
Agriculture (USDA) also encourage the recycling of agricultural and municipal wastes. These
wastes may contain heavy metals (e.g. arsenic, lead and cadmium) and persistent organic
compounds (e.g. dioxins and furans) in addition to the beneficial chemicals which are being
recycled into plant nutrient products. Biosolids (sewage sludge) are regulated hi the U.S. when
these products are applied to the land (EPA Part 503 Rule). EPA Part 266.20, "Recyclable
Materials Used hi a Manner Constituting Disposal," requires that fertilizers containing recycled
hazardous materials meet specific treatment standards.
This report is a compilation of existing information on inorganic fertilizers and liming
agents. The use and content of other types of materials used in agriculture, such as manures and
other biosolid materials, was not addressed in this study.
-------
Section 2 of this report provides an overview of the use of fertilizer in the United States,
including including total consumption rates for various fertilizer types by state, for agricultural
and non-agricultural use, and for specific crop types. This section also presents a brief profile
of the U.S. fertilizer industry, and a discussion of the types of recycled industrial wastes and
secondary materials that can be used in fertilizer manufacture;
Section 3 provides information on classification of fertilizers, and presents data on
concentrations of heavy metals and other contaminants by fertilizer type, as well as data from a
number of studies on soil metal concentrations.
Section 4 is a summary discussion of regulations and guidelines for fertilizers that have
been developed in the United States and other countries. This section also outlines regulations
for biosolids that are applied to land.
Section 5 combines data on the application rates for different fertilizer types with the data
on contaminant levels, to estimate the amounts of metals that may be added to soils from
fertilizer usage. These data are compared with regulatory standards and benchmarks, and to
background soil concentrations of metals.
1.1 PEER REVIEW PROCESS
This report was reviewed independently by members of a peer review panel. The panel
consisted of a diverse group of researchers and policy professionals in government, industry, and
environmental advocacy who, together, had considerable knowledge on all subject areas
addressed in this report. The members of this panel and their affiliations were:
Darlene H. Blair, Canadian Food Inspection Agency
Sally Brown, US Department of Agriculture- Agricultural Research Service
Stan Daberkow, US Department of Agriculture
Jacqueline Savitz, Environmental Working Group
James Skillen, The Fertilizer Institute
Steven Wong, California Department of Food and Agriculture.
The peer reviewers were invited to provide both general comments and specific suggestions
concerning the report.
The majority of the peer reviewer comments can be divided into five main subject areas.
These subject areas include:
• purpose of the report,
• definition of terms,
• use of benchmark standards for comparison of products,
• potential fertilizer problems beyond heavy metals in agricultural products, and
• technical issues related to clarity of discussion of calculation methods, and the role of
lime and gypsum in the fertilizer industry.
-------
The purpose of the report was not well understood by the reviewers, so that several
reviewers requested analyses, data collection, evaluation of EPA's next steps, and/or assessment
of EPA's policy position. These requests covered areas that far exceeded the scope and intended
purpose of the report. As a result of such reviewer comments, the executive summary and the
introduction were modified significantly to emphasize that this report is an information source,
and contains a compilation of available data on fertilizer composition, application rates, and
applicable regulations, and provides a calculated estimate of the possible soil metal
accumulations that may occur over tune with repeated applications of fertilizer products. The
report was not designed as an exposure assessment or risk assessment, either ecological or
human. EPA's next steps and policy position were not addressed as this would go beyond the
scope and intent of this report, and would logically be communicated to the public at a later time.
Terms that were used in the peer reviewed version of the report (e.g., contaminant,
hazardous waste) were viewed as significantly ambiguous to several reviewers so as to require
clarification and/or modification. Several reviewers suggested that a glossary of terms be added
at the beginning of the document, and this suggestion was implemented. The glossary covers
standard fertilizer terms and their abbreviations (e.g., DAP, diammonium phosphate), as well as
terms which may connote different things to different groups if not explicitly defined (e.g.,
industrial by-product). A consistent set of terms was then applied to the entire document, and
these terms were chosen as "neutral" in their connotations. For example, the term "heavy metal
contaminant" was replaced with "heavy metal constituent" because heavy metals such as zinc
and copper can be used as a nutrient in some circumstances and viewed as an undesirable
component in other instances. In addition, because of negative connotations to the word
"hazardous waste", especially as applied to materials that are legitimately reprocessed as
fertilizer materials or feedstocks, this term was replaced with "industrial by-product" in the
report.
Several reviewers questioned the appropriateness of the benchmark standards that were
employed in the evaluation of diverse fertilizer products. In particular, reviewers questioned the
use of heavy metals limits set in the Canadian Fertilizers Act and Regulations, and the
calculation of years required to double soil metal background levels with repeated yearly
additions of a given product. As documented in the report, the Canadian standards were not
established through a formal risk assessment, but were instead determined from the best
estimates of leading scientists in various fields as levels associated with no adverse effect to
plants, animals or land over the long term. These limits are being adopted by states and
AAPFCO at this time, in lieu of formal risk assessments, so that they constitute a useful and
consistent point of reference for comparisons. The report also characterizes fertilizer products
with respect to the length of time required for their consistent applications to double the average
background US soil metals levels. Although the doubling of soil metal levels may not be
associated with any known risk, these calculations help to put products, application rates and
fertilizer constituent levels hi the perspective of a measurable change to soils.
Due to the concern that recycled industrial by-products may have hazardous constituents
other than the heavy metals, the report was expanded to include discussions of other undesirable
components of fertilizers. In this section, attention was given specifically to dioxins/furans and
radionuclides. Some peripheral comments also noted the potential for pesticides, PAHs, and
PCBs to be present in industrial wastes, but organic constituents were not a primary focus of this
-------
report. Similarly, questions were raised about fertilizers other than those applied in production
agriculture, specifically those used in the home-and-garden arena. Because data were readily
available from several sources on concentrations of heavy metals in home-and-garden fertilizers,
these data were included in the report. However, because application rates for these products are
so varied among consumers, no attempt was made to estimate soil additions of metals from these
products.
Several comments made by reviewers suggested that there was some confusion about
what constituted an average fertilizer product. For this reason, there is a definition of average
product in the text, an expanded discussion of the calculation method, and examples that show
the manner in which both the percentage of the active nutrient ingredient and the individual
product heavy metal concentrations contribute to the soil addition rate. As a result of these
comments, text in both the executive summary and Section 5 has been augmented by figures
which provide a rapid perspective on product types that may require additional scrutiny due to
exceedances of Canadian standards or relatively short time of use before soil background metals
levels are potentially doubled. These figures provide an excellent perspective for final
conclusions of the report.
EPA has established a public record for the peer review of this report under
administrative record AR-208 , "Background Report on Fertilizer Use". The record is available
in the TSCA Nonconfidential Information Center, which is open from noon to 4 PM Eastern time
Monday through Friday, except legal holidays. The TSCA Nonconfidential information Center
is located in Room NE-B607, Northeast Mall, 401 M Street SW, Washington, DC.

2.0 FERTILIZER USE AND INDUSTRY CHARACTERIZATION
This section provides an introduction to the fertilizer industry in the United States.
Fertilizers are defined in the first subsection. Fertilizer consumption in the U.S. is described in
the second subsection. That subsection includes information on tons of fertilizers consumed by
types of fertilizer for individual states and regions of the country. Fertilizer use on agricultural
crops is provided, both amount consumed and application rates. In addition, fertilizer
consumption is broken down into that used for agriculture and other uses in the third and fourth
subsections. The final subsection provides an overview of the fertilizer industry describing the
market structure, production volumes and size distribution of producing firms.
This section addresses the questions:
• What constitutes a fertilizer and a liming material?
• How much fertilizer is used in the U.S.?
• How much of various kinds of fertilizers and micronutrients are used in the U.S.?
• How do the states and regions of the country differ in fertilizer use?
• What crops use the most of specific fertilizer types?
• What is known about non-farm fertilizer use?
• How is fertilizer made?
• What is known about the fertilizer industry in terms of production, revenue and
employment?
2.1. DEFINITION OF FERTILIZER AND LIMING MATERIAL
Fertilizer is defined as "any substance containing one or more recognized plant
nutrient(s) which is used for its plant nutrient content and which is designed for use or claimed to
have value in promoting plant growth" (Association of American Plant Food Control Officials -
AAPFCO, 1997b). A fertilizer material is a fertilizer which either
(a) "Contains important quantities of no more than one of the primary plant nutrients:
nitrogen (N), phosphorus (P) and potassium (K), or
(b) Has 85% or more of its plant nutrient content present in the form of a single chemical
compound, or
(c) Is derived from a plant or animal residue or by-product or natural material deposit
which has been processed in such a way that its content of plant nutrients has not
been materially changed except by purification and concentration." (AAPFCO)
Fertilizers may be composed of multiple fertilizer materials. In addition, fertilizers may contain
additives which "alter transformation in the soil, maintain good physical condition, reduce
corrosiveness and serve some purpose other than providing plant nutrients" (Meister, R.T., 1997)
and micronutrients. Primary nutrients are defined by the AAPFCO as nitrogen (N), available
phosphate (P2O5) and soluble potash (K2O). The AAPFCO defines secondary and micronutrients
as "those other than the primary nutrients that are essential for the normal growth of plants and
that may need to be added to the growth medium. Secondary plant nutrients shall include
calcium, magnesium and sulfur; micro plant nutrients shall include boron, chlorine, cobalt,
copper, iron, manganese, molybdenum, sodium and zinc." Calcium (liming materials and
-------
gypsum), magnesium (from dolomite limestone) and sulfur (in the form of inorganic sulfates and
sulfur in organic matter) are used to aid in fruit and leaf development and leaf color. More
detailed descriptions of the composition of fertilizers are provided in Section 3.
A liming material is defined as "a product whose calcium and magnesium compounds
are capable of neutralizing soil acidity" (AAPFCO, 1997b).
2.2. FERTILIZER CONSUMPTION IN THE U.S.
Both the AAPFCO and USDA collect information on fertilizer use in the United States.
The Economic Research Service (ERS) and National Agricultural Statistics Service (NASS) of
USDA and State Statistical Offices (SSO's) collect information on chemical use in agriculture,
including information on crops treated, acreage and costs. The AAPFCO, an organization of
officials, examiners, and researchers in North America charged with regulating fertilizer
materials and enforcing laws applied thereto, collects information on commercial fertilizers
consumed in North America, Hawaii, and Puerto Rico. Information provided in this chapter on
fertilizer use has been abstracted from both sources and several ancillary sources. The AAPFCO
uses the term "consumption" for their fertilizer statistics. Consumption, for the AAPFCO, means
data submitted by fertilizer control offices on sales or shipments for farm and non-farm use. The
USDA data record fertilizer application to agricultural land, which is a more specific definition
of use. Because there are no data on fertilizer stockpiling by the consumer, use and consumption
are used interchangeably in this report.
The AAPFCO reports that more than 54 million tons (110 billion Ibs) of commercial
fertilizers of all kinds were consumed in the United States in the year ending June 30,1996.
Primary nutrients (N, P, K) accounted for 91% of this total; liming materials accounted for about
4%, and organic fertilizers accounted for 1% of the total. Approximately 5% of the total (2.7
million tons) was due to secondary nutrients and micronutrients. Table 2-1 summarizes the U.S.
tonnage use of the different fertilizer types. The zinc and iron micronutrient fertilizers, which
have come under scrutiny lately as industrial waste by-products with heavy metal content,
comprise about 0.1% of the total tonnage of fertilizers consumed.
Table 2-2 summarizes the use of fertilizers in different regions of the United States. The
largest single category of fertilizers consumed in 1996 was the nitrogen materials (23 million
tons) and the smallest category is natural organic materials (0.57 million tons), which includes
compost, manure and sewage sludge. The West North Central region (13 million tons) and the
New England Region (0.4 million tons) are the areas consuming the most and least fertilizer in
the continental United States, respectively. These consumption values are totals and are not
adjusted for the amount of agricultural land in each region. The AAPFCO statistics presented in
Table 2-2 differ slightly from those presented in Commercial Fertilizers 1996 (AAPFCO and the
Fertilizer Institute (TFT), 1997) because this table was prepared from electronic files obtained
from the AAPFCO. Because of the inclusion of liming materials in these tables and some minor
differences in the definition of multiple nutrient fertilizers and "other" fertilizer groupings, these
fertilizer consumption values differ slightly from those presented in Commercial Fertilizers
1996.

Appendix A contains fertilizer consumption for individual states and Puerto Rico,
grouped into the regions of the country shown in Table 2-2 (pp. 8-14). These data are abstracted
from AAPFCO data files for the year ending June 30,1996. There are nine states with total
fertilizer consumption over 2 million tons. These states are, in order of increasing fertilizer
consumption: Florida, Minnesota, Ohio, Nebraska, North Carolina, Texas, Iowa, Illinois and
California. Table 2-3 below shows the fertilizer consumption (tons) of the top two states by
fertilizer category. Texas and Florida consume the most multiple nutrient fertilizers, while
Illinois consumes the most single nutrient nitrogen, phosphate and potash fertilizers. North
Carolina consumes the most organic fertilizers and liming materials, while California consumes
the most secondary nutrient and micronutrient fertilizers.

2.3. AGRICULTURAL FERTILIZER USE
The USDA ERS-NASS data presented in this section come from the most recent surveys
of field, fruit and vegetable crops. These surveys, the sampling methodology, coverage and data
collection are described in the USDA, ERS Agricultural Resources and Environmental
Indicators, 1996-1997 Appendix: Agricultural Resource Surveys and Data (1997).
Fruit and vegetable data were abstracted from the Chemical Use Surveys that were
initially funded under the 1989 President's Food Safety Initiative. These surveys are conducted
by NASS "using personal enumeration of a stratified systematic sample of growers who produce
at least one acre of the targeted crops." The information collected on fertilizer use, acreage
planted and application rates are survey data for the major crop producing states and do not
represent the totality of farms in the U.S. raising these crops. Surveys are conducted in odd
numbered years for fruit (latest available survey performed in 1995, reported in 1996) and even
numbered years for vegetable crops (latest available survey performed in 1994, reported in 1995;
the 1996 survey did not collect fertilizer data).
The latest field crop usage data, covering 70 to 90% of the total U.S. crop, are from the
Agricultural Resources Management Survey (ARMS) of 1996 which combines the former
Cropping Practices Surveys with the Farm Costs and Returns Survey. This survey has three
phases. Phase n, conducted in the autumn, collects data on agricultural production practices,
resource and input use and production. In this survey, "a multi-frame, stratified sampling
procedure is used. Results are weighted and aggregated to develop state, regional and national
estimates." The ARMS collects additional information on a selected field crop in certain years.
For example, in 1996 the ARMS collected data on tobacco.
2.3.1 Field Crops
The USDA, ERS, NASS (1997) collected data on selected field crops in the major states
with approximately eighty percent of the U.S. acreage for these crops. Table 2-4 shows the
number of acres planted, the total amount of N, P (P2O5) and K (K2O) fertilizers applied and N, P
and K application rates for these field crops (note that in this section on fertilizer use, P refers to
phosphate fertilizers, not phosphorus, and K refers to potash, not potassium). Potatoes have the
highest average application rates for nitrogen fertilizers (195 Ibs/acre) and phosphate fertilizers
(173 Ibs/acre), while application rates of potash are highest on tobacco (203 Ibs/acre). Potatoes
and tobacco, however, each have fewer than 1 million acres planted. More acres are planted with
com (approximately 70 million acres) than any other crop in the U.S., and the application rates
are 133 Ibs/acre N, 57 Ibs/acre P2OS and 79 Ibs/acre K2O. Thus, in terms of total applied
fertilizer, acreage in corn, in the aggregate, receives the most fertilizer.
Information on lime, sulfur, manure and micronutrient use is available only from previous
USDA surveys. The USDA, ERS, Cropping Practices Survey field crop data for crop year 1994
and 1995 (USDA, AREI, May, 1996) report some information on these fertilizers and soil
amendments. Table 2-5 shows the number of field crop acres receiving nutrients and application
rates for sulfur and lime for 1994 and 1995. Almost 60 percent of the potato acreage receives
sulfur and micronutrient fertilizers, and this is a much greater percentage than any of the other
field crops. Application rate for sulfur on potatoes is also much higher than other field crops (82
15
-------
Ibs/acre for potatoes compared to 11-13 Ibs/acre for other field crops). Six percent of potato
acreage receives lime, and while this is higher than other crops, it is only slightly higher.
Fourteen percent of the corn acreage in 1995 received manure treatments. All other crops had
fewer acres treated with manure.

Appendix B (Table B-l) presents corn, cotton, potato, soybean, tobacco, and wheat data
for primary plant nutrient use (N, P2O5 and K2O), fertilizer (total N, P2O5 and K2O) and fertilizer
application rates from the most recent USDA survey. The Agricultural Resources Management
Survey was conducted in the fall of 1996 (USDA, NASS, ERS, September, 1997). In 1996, the
survey covered the major field crop producing states with data from 63 percent (potatoes) to 88
percent (corn) of all U.S. acreage for these field crops. Corn is the field crop with the most acres
planted (70 million) and the most nitrogen (9 billion pounds), phosphate (3 billion pounds) and
potash (4 billion pounds) fertilizers consumed. Ninety-nine percent of the tobacco crop (0.4
million acres) and greater than ninety percent of the potato crop (0.8 million acres) is fertilized
with N, P2O5 and K2O fertilizers. Less than 30% of the soybean crop (50 million acres) receives
application of these primary nutrients.

2.3.2 Fruits and Vegetables
In addition to field crops, the USD A, ERS, NASS collects information on fertilizer usage
on fruit and vegetable crops (USDA, ERS, NASS, 1997b and USDA, ERS, NASS, 1996).
Appendix B, Tables B-2 and B-3 present information on acres planted, total N, P, and K applied
and the application rates per crop year for fruits (1995) and vegetables (1994) in selected states.

It should be noted that the application rates presented in these tables are per crop year and may
represent multiple applications at lower rates.
There is considerable information in the fruit and vegetable tables in Appendix B. These
data are summarized in Tables 2-6 and 2-7. These tables show the acres planted, the total pounds
of N, P2O5 and K2O fertilizers applied and the application rates per crop year for vegetable and
fruit crops. When more than one state was included in the USDA surveys for a specific crop, the
total acreage and pounds of fertilizer applied are presented. Average and ranges of fertilizer
application rates are shown for the producing states. In some cases only a single producing state
was included in the survey, and the values shown in the table are for only that state.

-------
Fruit and vegetable crops with the highest average application rates (Ibs/acre) per crop
year are fresh tomatoes (N: 264 Ibs/acre and K20:408 Ibs/acre) and celery (P2O5:195 Ibs/acre).
Most acreage is planted with processing sweet corn, tomatoes and green peas. State-specific data
are presented in Appendix B. Crops with the highest application rates for nitrogen fertilizers are
watermelon, head lettuce and other lettuce in Arizona. Crops with the highest application rates
for phosphate fertilizers are processing cucumbers in North Carolina, bell peppers in California
and head lettuce in Arizona. Crops with the highest application rate of potash fertilizers are fresh
tomatoes, celery and bell peppers in Florida.
2.4. NON-AGRICULTURAL FERTILIZER USE
In addition to the fertilizer consumption by state and fertilizer type, the AAPFCO
database (AAPFCO, 1997a) contains estimates of the farm and non-farm consumption data.
Table 2-8 summarizes these data for the states, and Appendix C contains the farm and non-farm
consumption (tons) for each of the individual fertilizer types. Several states have no recorded
non-farm consumption, therefore no non-farm percentages were reported (i.e. the farm use was
coded as 1 and non-farm use was coded as 2, and there were no 2s). Farm and non-farm use data
were not reported for the states of Arkansas, Iowa, Kentucky, Ohio and Texas (i.e., the field for
the variable "use" was blank). Non-farm uses include application around residences, golf
courses, other recreational fields, cemeteries and public property.
Over 2,650,000 tons of fertilizer was used on non-agricultural land according to those
states reporting data to the AAPFCO. This represents approximately 6% of the total fertilizer use
defined as farm and non-farm. The states with the highest non-farm consumption of fertilizers
are Florida (393,012 tons) and California (320,367 tons). The states with greater than 30% non-
farm fertilizer use are New Jersey (124,661 tons), Nevada (12,408 tons) and Vermont (11,904
tons).
The types of fertilizers used on farm and non-farm land differ. Table 2-9 shows the farm
and non-farm consumption of various fertilizer types for the states with the highest consumption
in terms of non-farm percent or total tons, as described in the previous paragraph. Detailed
information for all states is provided in Appendix C. Multiple nutrient, and organic fertilizers are
used in higher percentages on non-farm land than other fertilizers, particularly the single nutrient
N, P2O5 and K2O fertilizers.
2.5 U.S. FERTILIZER INDUSTRY PROFILE
Information in this section has been abstracted from an EPA report (The U.S. Fertilizer
Industry: A Profile, U.S. EPA, Economics, Exposure and Technology Division, OPPT,
November, 1997). Details of the production process, industry definition, domestic production,
imports and exports, firms in the fertilizer industry and market structure may be found in that
report.
Nitrogen fertilizers are derived from synthetic ammonia that is produced from natural gas.
Approximately one-third of nitrogen fertilizer is applied as anhydrous ammonia (soil injection).

Approximately two-thirds of nitrogen fertilizers are ammonium salts and other nitrogen-
containing chemicals (see Table 2-1). Phosphate fertilizers are made by treating phosphate rock
with sulfuric acid to produce phosphoric acid. Approximately two-thirds of applied phosphorus
is in the form of mono- and diammonium phosphate. Phosphate rock deposits are found
primarily in Florida, North Carolina and Idaho, and the U.S. is a net exporter of phosphatic
fertilizer. Potash (K2O) is derived from marine deposits and brines. Most potash fertilizer
(approximately 95%) is in the form of potassium chloride. Potassium sulfate and potassium
nitrate are also used on certain crops. The U.S. imports most of its potash from Canada.
The U.S. Census of Manufactures classifies fertilizer industries in the following Standard
Industrial Classification Codes (SIC):
2873 Nitrogenous fertilizer materials, this SIC includes
Establishments that only produce nitrogen fertilizer materials
Establishments that both manufacture nutrients and prepare fertilizer mixtures
2874 Phosphatic fertilizer materials, this SIC includes
Establishments that only produce phosphate fertilizer materials
Establishments that both manufacture nutrients and prepare fertilizer mixtures
2875 Fertilizer mixing only, this SIC includes
Establishments that only mix raw materials
In addition, producers of other fertilizer materials, such as potassium chloride, will be found in
SIC 2819 - Industrial Inorganic Chemicals, not elsewhere classified. Because many fertilizer
producers (particularly micronurrient fertilizer producers) are included with the production of
inorganic chemicals for all purposes, it is difficult to specifically define industries producing
fertilizers. The real value of shipments in 1995 (in 1992 dollars) for SICs 2873,2874 and 2874
are $3,435.3 million, $3,882.9 million and $2,336.8 million, respectively. Total employment for
these three SICs were 7,300, 8,600, and 8,400 in 1995.
The total number of companies in the three fertilizer SICs are shown in Table 2-10.
There are 10 companies in SIC 2873 with sales over $1 billion and 28 companies with sales <$10
million. Two companies in SIC 2874 have sales over $1 billion and 12 companies have sales
<$10 million. Only one company in SIC 2875 has sales over $1 billion, but 78 companies have
sales <$10 million. Therefore, there are few large firms hi these SICs. These companies are also
small in terms of number of employees. Figures are provided in the EPA report. The report
indicates that there are 77 of 114 companies hi SIC 2873 employing fewer than 1000 persons.
There are 36 companies hi SIC 2874 and 148 companies hi SIC 2875 considered small
businesses based on the standards of the Small Business Administration (those employing fewer
than 500 persons).
Manufacturers, formulators, distributors/dealers and brokers of the micronutrients boron,
copper, iron, manganese, molybdenum and zinc generally deal with one or more of these
chemicals. The EPA report (Table 3-2) lists 74 companies that fit the category of micronurrient
manufacturers, formulator etc.

Cement kiln dust may be used as a liming material because of the high calcium oxide
content. The U.S. EPA report to Congress for Cement Kiln Dust, Volume E: Methods and
Findings, December, 1993 reports that 122,000 tons of cement kiln dust are used as a soil
amendment, and 57,849 tons are used as liming materials.
Most nitrogenous fertilizer is produced in the south central U.S., and most phosphorus
fertilizer is produced from phosphate rock deposits in the southeastern U.S. As described
previously, most potash comes from Canada. Plants that mix fertilizer are dispersed throughout
the country. Most of these plants are small, serving local (within approximately 30 miles of the
plant) and regional markets. These plants bulk blend products custom made for the local markets
based on crops and soil conditions. Micronutrients, pesticides and even seeds are sometimes
added to custom blends. Many of the firms have soil testing laboratories to assist the farmers in
determining the optimum fertilizer blend.
In the last two decades, fertilizer production has increased fifty percent. Greater than 10
percent of the volume is exported. Most of the companies, particularly fertilizer mixing
companies, are small.
2.6 RECYCLED MATERIALS IN FERTILIZER MANUFACTURE
A number of industrial wastes and by-product materials are used hi the manufacture of
inorganic fertilizers. Such recycling practices are most common hi the manufacture of
micronutrient fertilizers, particularly zinc fertilizers. The following recyclable materials can be
used as feedstocks to make zinc micronutrient fertilizers:
• Electric arc furnace dust (dust collected from emission control devices hi steel
manufacturing), otherwise known as K061 (its RCRA waste code)
• Brass foundry dusts (also from emission control devices)
• Tire ash (typically, ash from burning of tires for energy recovery)
• Galvanizing fines
25
-------
K061 is regulated as a listed hazardous waste under RCRA, and can contain significant
amounts of non-nutritive metals such as lead and cadmium. Brass foundry dusts often exhibit a
hazardous characteristic when tested according to the Toxicity Characteristic Leaching Procedure
(TCLP), usually because of lead and cadmium. Tire ash is also typically a characteristic
hazardous waste due to cadmium concentrations. Galvanizing wastes typically do not exhibit a
hazardous waste characteristic. It should be noted that non-waste feedstocks that are also used to
make zinc fertilizers, such as refined ores from lead mining, can often have concentrations of
non-nutritive metals comparable to those in waste feedstock materials. As presented in Chapter
3 of this report, levels of metal contaminants in zinc fertilizer products vary substantially, and
depend largely on how the raw materials are processed, rather than on which type of feedstock is
used.
Another type of hazardous waste-demetallized photographic fluids—is used to make
multinutrient fertilizer products (http://www.itronics.com)
Further discussion of how RCRA regulates recycling of hazardous wastes and hazardous
secondary materials to manufacture fertilizers is presented in Chapter 4 of this report.
Examples of industrial secondary materials that are not currently regulated by RCRA as
hazardous wastes and that can be recycled to manufacture fertilizers include:
• Cement kiln dust (CKD), which is used primarily as a lime substitute to adjust soil pH
• Mining waste; at least one iron fertilizer product is made from mine tailings
(www.konite.com)
• Gypsum (a source of calcium, sulfur and boron) from coal-burning electric power
generation facilities
• Ash from wood-burning power generation facilities
• Pulp and paper sludges, which are generally used as soil amendments

3.0 COMPOSITION OF FERTILIZERS AND SOILS
Phosphate fertilizers are known to contain varying levels of heavy metals such as
cadmium, lead, nickel and chromium (Mortvedt, 1987; Charter et al., 1993). These metals
originate in the phosphate rock (Mortvedt and Giordano, 1977; Kpomblekou-A and Tabatabai,
1994); much of the cadmium, and other metals, remains with the phosphate during processing
(Wakefield, 1980). Phosphate fertilizers, though, are by no means the only fertilizer product
with measurable levels of heavy metals. Studies have documented the presence of heavy metals
hi zinc micronutrient fertilizers (Mortvedt, 1985), in biosolids (Matthews, 1996) applied to
agricultural lands, and organic fertilizers such as manure and compost (Raven and Loeppert,
1997; Arora et al., 1975). Because these heavy metals may enter the human food chain either
directly (via uptake into the grain, fruit or vegetable) or indirectly (via ingestion by foraging
animals), studies have been conducted recently to compare the soil background levels of these
metals with levels in fertilizer materials (Mermut et al., 1996) and to assess plant uptake and
distribution of these metals (Mortvedt, et al., 1981; Mortvedt and Giordano, 1977; Chaney, 1983;
Gavi et al, 1997).
This section addresses the following questions:
• What are the concentrations of heavy metals in U.S. soil and soil in other parts of the
world?
• What is the macronutrient composition of different fertilizers?
• What are the heavy metal concentrations in fertilizers and liming materials?
• What other potentially hazardous constituents may be present in fertilizers and liming
materials?
3.1 HEAVY METALS IN SOILS
Because heavy metals are naturally present in soil, it is instructive to begin the
assessment of fertilizer metals addition to soil with an evaluation of the background levels of
these metals in soil. Over the last twenty years, a number of studies have been carried out to
assess the levels of metals in soils. Because those studies were carried out for scientific reasons
other than assessment of effects of heavy metals addition from fertilizers, the site selection
criteria for samples and statistical treatment of the data are not generally comparable across
studies. However, these studies, in toto, may provide some insight into potentially "typical"
values for metals in soils.
Table 3-1 provides an overview of sixteen different studies of metals in soils in which
samples were collected from reasonably large (several hundred square miles) geographic areas so
that minor site-to-site variations may be negligible. As listed in Table 3-1, the studies in which
the number of samples substantially exceeds the number of sites indicates that one or more
subsurface soil samples (indicated as "sub") were collected hi addition to the surface soil sample
(indicated as "surf). The abbreviated results of several studies (No. 3 and 16) were listed in
another study (Holmgren et al., 1993) for comparison purposes, and for those, complete
site/sampling descriptions are not available. The notation "nd" indicates that information such as
the number of sites has not been determined. Sampling locations included agricultural lands

(ag) and agricultural lands to which sewage sludge had not been applied (ag/no ss). True
background soil samples (natural) were collected in pristine, undisturbed environments. The
English and Chinese study stated that soils were collected in all regions except those directly
impacted by an adjacent industrial source (McGrath et al., 1986; Chen et al., 1991).
The generation of geometric means for soil metals concentrations is the preferable
statistical treatment of comprehensive studies because of the logarithmic distribution of metal
concentrations commonly observed in soils. For those studies where both geometric and
arithmetic means were available, both statistics are included hi Table 3-2 of average
concentrations for cadmium (Cd), lead (Pb), arsenic (As), chromium (Cr), mercury (Hg), nickel
(Ni), vanadium (V), copper (Cu) and zinc (Zn). As indicated by "nd" (not determined), various
studies did not include measurement of all metals.
In general, for Studies 1 and 2 in the USA (Holmgren et al., 1993; Shacklette and
Boerngen,1984), metals concentrations for the agricultural lands without sewage sludge addition
(Study 1) are comparable to those from the natural lands (Study 2). These values for the USA
agricultural lands contrast somewhat with both the Ontario and Saskatchewan agricultural land
studies (Studies 7 and 8) (Frank et al., 1976; Mermut et al., 1996)) where soil cadmium, and
possibly lead and zinc, were elevated relative to U.S. background levels, possibly due to
anthropogenic additions (e.g., fertilizer, urban atmospheric deposition). While anthropogenic
input to soil metals levels is suggested by the authors for comparisons of the surface and
subsurface soil samples in the Saskachewan study, the climatology of the region (limited rainfall
relative to southern USA regions) and the mineralogy of the area may also help to explain
differences in soil metal content between the U.S. and Canadian plains. In support of
anthropogenic input, cadmium, lead and zinc in low clay content soils (clay soils having higher
metals levels naturally) show that these metals are at statistically higher levels in surface soil
relative to subsurface soil. Fertilizer addition to these Canadian soils has occurred for 30-40
years.
The ranges of metal concentrations for the surface soils are listed in Table 3-3 for
reference only. As anticipated, both extremely high and low values were found in most studies,
and in that regard, the range of concentrations in US "background" soils often exceeds that found
in the Canadian studies. In the U.S., metals are generally found at higher levels in the West
relative to the East and in the North relative to the South. Of note in the study conducted in
Poland and western USSR, ranges of soil metals concentrations were given for both background
soils and then also for soils from industrial regions, urban gardens, vineyards and fertilized
agricultural regions. On the basis of these results, the governments have outlined broad land
regions based on soil metals concentrations and then made recommendations on the types of
agricultural practices appropriate for these lands.
3.2 NITROGEN. PHOSPHATE AND POTASH COMPOSITION OF NPK FERTILIZERS
Due to the diversity of NPK fertilizers, several authors have segregated and analyzed
these fertilizers by class. Specific types or classes of NPK that have been analyzed include MAP
(monoammonium phosphate), DAP (diammonium phosphate), TSP (triple super phosphate), MP

(potash or potassium), single nutrient fertilizers and multiple nutrient fertilizers. A complete
listing of the various types of NPK fertilizers and their macronutient content (i.e., N, P2O5, and
K2O) is given in Table 3-4 for reference.
3.3 HEAVY METALS IN FERTILIZERS AND LIMING MATERIALS
Macro- and micronutrient fertilizers and liming materials may contribute heavy metals to
surface agricultural lands. Some of the raw materials that provide this input include rock
phosphates (for NPK and NPKS fertilizers), high zinc-content recycled industrial waste (for zinc
micronutrient fertilizers) and municipal sewage sludge (for organic fertilizers). In general, on a
mass concentration basis (mg/kg), the NPK fertilizers are by comparison with the zinc
micronutrient fertilizers, lower in metals content.
Concentrations of nine selected metals (cadmium, lead, arsenic, chromium, mercury,
nickel, vanadium, copper and zinc) hi world-wide rock phosphates are listed in Table 3-5.
Sources of rock phosphates in the USA include North Carolina (NC), Florida (FL) and Idaho
(ID). Specific analyses of rock phosphates from the U.S. are listed at the end of Table 3-5. No
analytical results were specifically attributed to analyses of Idaho rock phosphates.
Table 3-6 shows the results for analyses of diverse NPK fertilizers. It is especially
instructive to separate the analyses of MAP, DAP and TSP as the concentrations of metals (with
possible exception of Ni) appear to increase with this sequence of products. (Again, "nd" in
these tables indicates that the analyte was not determined. If analyzed and not detected, the
analyte is listed as being less than the method detection limit if available.) Cadmium levels less
than 10-50 ppm appear consistently throughout these analyses; however, some fertilizer samples,
such as those commercially-available hi California, have concentrations greater than 150 ppm.
Tests of rock phosphates for heavy metal content have indicated that the quality of the ores has
been declining over the last two decades (Charter et al., 1993). The heavy metals content of ore
may increase with depth of the mine, so that some older mines may produce materials with
increasing cadmium levels.
For comparison, the concentrations of metals in various types of organic fertilizers are
listed in Table 3-7. The organic fertilizers include composts, bone meal, manures and municipal
sewage sludge (sew si). The levels of Cd, Pb, Ni, V and Cu hi these fertilizers are roughly
equivalent to levels found in NPK fertilizers; however, Zn levels are often higher. Variability
beyond that indicated here is anticipated hi the sewage sludges because of the varying nature of
the incoming waste streams.
The concentrations of metals in various secondary nutrient and micronutrient fertilizers,
primarily Zn fertilizers, are listed hi Table 3-8. As indicated earlier, on a mass concentration
basis, these fertilizers have higher Cd, Pb, Ni and Cu levels than those found in NPK fertilizers.

The concentrations of metals in diverse commercially-available fertilizers from two
studies (reported by Larimer and the Texas Agricultural Experiment Station, 1997a and 1997b)
are listed in Table 3-9. The levels of Pb in several products suggest that these products may be
derived from recycled industrial waste, although no designation was given to these fertilizer
formulations.
The concentrations of selected metals in liming agents are shown in Table 3-10. With
possible exception of the kiln dust lime, the mass concentrations reported here appear similar to
levels reported for other organic and inorganic fertilizers.
The concentrations of metals in the various gypsum and phosphogypsum samples are
listed in Table 3-11. Approximately 5 tons of phosphogypsum are produced as a by-product in
the production of 1 ton of phosphoric acid fertilizer. On a worldwide scale, of the residual
phosphogypsum produced, 14% is reprocessed, 28% is discharged to water and 58% is stored in
stacks (Carmichael, (1988) in Rutherford, et al., 1994). Some of this material is used as a soil
amendment, especially for clay soils. Its greater agricultural use, though, is found in its ability to
supply secondary nutrients Ca and S.
3.4 RADIOACTIVE COMPOUNDS IN FERTILIZERS
Phosphate and phosphogypsum fertilizers apph'ed to agricultural lands contain trace
radioactive nuclides which originate with the rock phosphates. Radionuclides, including
uranium (U), radium (Ra) and thorium (Th), and their decay products can remain hi these
fertilizer products. Uranium in rock phosphate ranges from 3-400 mg/kg in deposits around the
world (Mortvedt, 1992). During processing, much of the U, up to 67% of the initial
concentration, and Th will remain with the phosphate fertilizer, while Ra will be contained
primarily in the phosphogypsum by-product (Rutherford et al., 1995). The U content of triple
superphosphate will be greater than that of phosphoric acid because the phosphoric acid, initially
obtained from the rock phosphate is concentrated and reacted with additional rock phosphate,
resulting in an U concentration approximately 3 times greater than in the phosphoric acid (Erdem
et al., 1996).
The concentrations of radionuclides 23 8U, 226Ra and 232Th in Bq/kg and mg/kg (as
available) from various studies are summarized in Table 3-12. As shown mere, 238U
concentration in rock phosphates around the world varies considerably, 90-4800 Bq/kg; a similar
range is found for 226Ra, 40-5022 Bq/kg. The 232Th concentrations are lower, 16-622 Bq/kg.
The rock phosphate from Tunisia, with 23 8U content of 4400 Bq/kg, 226Ra content of 5022
Bq/kg and 232Th content of 622 Bq/kg, when processed into superphosphate had concentrations
of 3740, 3394 and 420 Bq/kg for U, Ra and Th respectively, and when processed into triple

superphosphate had concentrations of 6940, 3116 and 362 Bq/kg for U, Ra and Th, respectively.
The residual phosphosgypsum had 226 Ra content of 3219 Bq/kg (Makwabe and Holm, 1993).
Phosphogypsum concentrations of 226Ra are variable, as reported in these studies.
Concentration of 226Ra ranged from 610 Bq/kg in a Florida-rock phosphate derived
phosphogypsum to 3219 Bq/kg in the phosphogypsum derived from the Tansanian rock
phosphate.
3.5 PERSISTENT ORGANIC CHEMICALS IN FERTILIZERS AND LIMING MATERIALS
The presence of chlorinated dibenzodioxins and chlorinated dibenzofurans (CDD/CDF)
and polychlorinated biphenyls (PCB) in fertilizer materials (other than biosolids) has been
investigated for cement kiln dust (CKD) used as a liming material. These data have been
incorporated into the U.S. EPA Dioxin Reassessment document (U.S. EPA, Office of Research
and Development, 1994).
Terra- through octa CDD and CDF were detected in the "gross CKD" (that being the
initial particulate material collected as an emission product by the air pollution control device
from kiln operation) of 10 of 11 kilns sampled, where 6 of the kilns burned hazardous waste
concurrently with a fossil fuel. These same CDD and CDF were also detected in the "net CKD"
(that being the particulate material collected by the air pollution control device following
recycling of gross CKD back through the kiln system; net CKD is used for land disposal) of 8 of
the 11 kilns samples. Analyses for 7 PCB congeners was also conducted, but these were not
detected in the CKD samples.
The CDD and CDF content of gross CKD was 0.008-247 ng TEQ (toxic equivalency
units)/kg; the CDD and CDF content of net CKD was 0.045-195 ng TEQ/kg. The mean
CDD/CDF content of net CKD for hazardous waste-burning kilns was higher than that for the
kilns which burned only fossil fuel, 35 ng TEQ/kg versus 0.03 ng TEQ/kg, respectively. One
kiln sample had a CDD/CDF concentration that was two orders of magnitude greater than that of
the other kilns; if this one result were eliminated as atypical, then the mean CDD/CDF
concentration in net CKD for hazardous waste-burning kilns would be 2.9 ng TEQ/kg, as
opposed to 35 ng TEQ/kg. (Note: for consistency with concentration units used earlier for metals
in fertilizer products, 2.9 ng/kg= 2.9 x 10"6 mg/kg and 35 ng/kg= 35 x 10"6 mg/kg.).
The TEQ for dioxins in other fertilizer and liming materials has been measured recently
by the State of Washington, Department of Ecology. These data are shown in Table 3-13. As
listed there, these products are derived from industrial wastes such as CKD, K061 waste, and tire
ash. The total dioxin toxic equivalency (TEQ) concentration, as defined in footnote b of Table 3-
13, ranges from approximately 0.5-350 ng/kg in actual fertilizer materials, and as high as 815
ng/kg hi the raw material KO61 used to produce the corresponding zinc fertilizer.
3.6 HEAVY METALS IN HOME GARDENING PRODUCTS
The results of recent analyses for heavy metals in home gardening products are listed in
Table 3-14. The concentrations of metals in the individual products are listed. The mean and
median concentrations, and range of concentrations for product categories, are listed when more
51
-------
than three products were analyzed. Levels of these metals, on a mass concentration basis, are
similar to those found in agricultural products.

a) In calculating the TEQ, concentrations of forms (congeners) that were not detected were assumed to equal
0.
b) TEQ Concentration: There are 17 forms of dioxins considered to be toxic, but not all are equally toxic.
The most toxic dioxin is called 2,3,7,8-TCDD, and other similar dioxins have been assigned toxicity values
relative to it. These relative toxicity values are called toxicity equivalency factors (TEFs). 2,3,7,8-TCDD is
assigned a TEF of 1, and the others are assigned values less than 1. Total concentrations of dioxins in the
environment are reached by factoring in the TEF of each form of dioxin before adding them together. The
resulting concentration is referred to as TEQ (toxic equivalent).

4.0 FERTILIZER REGULATIONS, STANDARDS, GUIDELINES AND BENCHMARKS
This section describes the regulation of fertilizers and soil amendments and the
constituents of these products. Since there is no federal fertilizer law, the state laws regulating
fertilizer composition and efficacy are described first. Federal rules which may be of some
relevance for regulating the use of industrial by-products in fertilizers are discussed in the second
sub-section. The third sub-section describes international fertilizer regulations. The fourth sub-
section describes federal and international standards for the land application of sewage sludge
and include limits for metals in sludge and soil following sludge application.
This section addresses the questions:
• Who regulates fertilizer composition and application?
• What are the state regulations regarding fertilizer composition?
• Although there are no specific Federal laws regarding fertilizer composition or
efficacy, what Federal regulations may be applied to some aspect of fertilizer use and
soil contamination?
• What international laws exist governing fertilizer application and soil contamination?
• What are the regulations for application of biosolids (sewage sludge) to land?
4.1. STATE REGULATIONS
State regulations for fertilizers are generally developed and administered by state
agriculture departments. Such regulations primarily address efficacy claims and composition
statements of the active ingredients displayed on fertilizer labels. Most states have fertilizer
regulations similar to that of the AAPFCO model Uniform State Fertilizer Bill reproduced in
Appendix D. Section 4 of that bill requires registration and/or licensing of each brand and grade
of fertilizer by the person whose name appears on the label before the product may be
distributed. The application for registration includes the brand and grade and a guaranteed
analysis. Section 3 of the bill defines guaranteed analysis as:
"the minimum percentage of plant nutrients claimed in the following order and form:
(D
(2)
(3)
Total Nitrogen (N)
Available Phosphate (P2O5)
Soluble Potash (K2O)
For unacidulated mineral phosphatic material and basic slag, bone, tankage or other
organic phosphatic materials, the total Phosphate and/or degree of fineness may also
be guaranteed.
Guarantees for plant nutrients other than nitrogen, phosphorus and potassium may
be permitted or required by regulation by the . The guarantees for such other
nutrients shall be expressed in the form of the element. The source (oxides, salts,
chelates, etc.) of such other nutrients may be required to be stated on the application
for registration and may be included on the label. Other beneficial substances or
compounds, determinable by laboratory methods, also may be guaranteed by
54
-------
permission of the and with the advice of the Director of the Agricultural
Experiment Station. When any plant nutrients or other substances or compounds
are guaranteed, they shall be subject to inspection and analysis in accord with the
methods and regulations prescribed by the ."
Thus, any claims that are made concerning chemicals necessary or conducive to plant growth
must be substantiated. If a chemical included in the analysis is not listed on the label, no analysis
is required, except (Section 12, Adulteration):
"No person shall distribute an adulterated fertilizer product. A fertilizer shall be deemed
to be adulterated:
(a) If it contains any deleterious or harmful substance in sufficient amount to render it
injurious to beneficial plant life, animals, humans, aquatic life, soil or water when
applied in accordance with directions for use on the label, or if adequate warning
statements or directions for use which may be necessary to protect plant life,
animals, humans, aquatic life, soil or water are not shown on the label."
Consistent with the AAPFCO model fertilizer bill, most states currently have a general
prohibition on distribution of "adulterated" fertilizer products. AAPFCO and the states have
only recently begun to develop specific guidelines on what might constitute adulterated products.
In 1998 AAPFCO amended its Uniform State Fertilizer Bill to provide further interpretation of
what constitutes adulteration of fertilizers. Under AAPFCO's Policy Statement #25 entitled
"Metals in Fertilizer Materials", fertilizer materials are to be considered adulterated if they
contain metals in amounts greater than the levels established by the Canadian Standards, and that
biosolids are adulterated when they exceed the levels of metals permitted by the U.S. EPA §503
regulations. Under Policy Statement #26, products that meet the guidelines for metals may
include the following statement on the label: "When applied as directed, this product meets the
guidelines for metals adopted by the Association of the American Plant food Control Officials."
AAPFCO is also currently developing additional labeling recommendations that would indicate
the ingredients contained in fertilizer products.
State-specific fertilizer initiatives (as of February 1999) include the following
• In 1998 the State of Washington became the first state to enact legislation to
comprehensively regulate contaminants in fertilizers. Washington's Safe Fertilizer
Act mandates a set of new regulatory requirements for contaminant testing,
registration and labeling, and contaminant standards. The Act specified that until
national risk-based standards are developed, Washington would adopt the Canadian
fertilizer standards on an interim basis. The Act also allows adjustments to the
Canadian standards based on application rates that are consistent with agricultural
practices in the State of Washington. Further studies of heavy metals and dioxins in
fertilizers and soils in Washington, and new research on plant biouptake of metals
(being conducted by Washington State University), were also mandated by the Act.
55
-------
• The State of Texas also enacted in 1988 new regulations governing fertilizer
contaminants analogous to those of Washington, though based on the EPA §503
standards for sewage sludge rather than the Canadian standards.
• The State of California (CDFA and CalEPA), has prepared a risk assessment
characterizing acceptable lead, cadmium and arsenic levels in fertilizer materials,
based on California soils and agricultural practices ("Development of Risk-Based
Concentratoins for Arsenic, Cadmium, and Lead in Inorganic Commercial
Fertilizers", March 1998, Foster Wheeler Environmental Corporation). California
does not yet have comprehensive fertilizer regulations in place, although legislative
proposals are under development.
• In Pennsylvania, for fertilizers made from industrial waste products, the Department
of Agriculture requires testing data from manufacturers and approval of the
registration by the Department of Environmental Protection.
4.2. FEDERAL REGULATIONS
There are no specific Federal laws regulating the composition or efficacy of fertilizers.
There are regulations concerning the production, use and disposal of hazardous materials,
drinking and surface water contamination and air pollution that are indirectly relevant to the use
of hazardous materials in fertilizers and the application of fertilizers to land. In addition, the
Hazardous Waste Regulation, 40 CFR Part 503, Standards for the Use or Disposal of Sewage
Sludge, provides limits for the concentration of metals in sludge that is applied to land and to the
chemical loadings on the land following application. This standard is described in detail in
Section 4.4. Other U.S. regulations which are applicable, in part, to the use of industrial by-
products in hazardous wastes are discussed below.
4.2.1 OSHA
The Occupational Safety and Health Adrninistration (OSHA) Hazard Communication
Standard (29 CFR 1910.1200) applies to chemical manufacturers and importers of "hazardous
chemicals" which includes agricultural operations. This standard provides for a comprehensive
program of hazard communication including warning workers about chemical hazards via labels,
material safety data sheets (MSDSs), other warning mechanisms and employee training. The
standard does not apply to family members working on farms, only employees.
One provision of this regulation is that chemicals in concentrations of 1% or more (0.1%
for carcinogens) must be listed on the MSDSs for products used in the workplace.
Manufacturers and importers must provide MSDSs for their products. Specifically:
(1) 1910.1200 (b)(l)
This section requires chemical manufacturers or importers to assess the hazards of
chemicals which they produce or import, and all employers to provide information
to their employees about the hazardous chemicals to which they are exposed by
56
-------
means of a hazard communication program, labels and other forms of warning,
material safety data sheets, and information and training.
(2) 1910.1200 (d)(l)
If a mixture has not been tested as a whole to determine whether the mixture is a
health hazard, the mixture shall be assumed to present the same health hazards as do
the components which comprise one percent (by weight or volume) or greater of the
mixture, except that the mixture shall be assumed to present a carcinogenic hazard
if it contains a component in concentrations of 0.1 percent or greater which is
considered to be a carcinogen under paragraph (d)(4) of this section;
The requirement for MSDSs does not apply, however, for chemicals subject to labeling
requirements of specific acts such as the Federal Insecticide, Fungicide and Rodenticide Act
(FIFRA), the Toxic Substance Control Act (TSCA), the Federal Food, Drug, and Cosmetic Act
(FFDCA), and consumer products regulated under the Consumer Product Safety Act (CPSA) and
the Federal Hazardous Substances Act (FHSA). Also, this section of the OSHA regulations do
not apply to any hazardous waste as defined by the Solid Waste Disposal Act (SWDA), as
amended by the Resource Conservation and Recovery Act (RCRA) and any hazardous substance
defined by the Comprehensive Environmental Response, Compensation and Liability Act
(CERCLA) when the product is the focus of remedial or removal action being conducted in
accordance with EPA Regulations.
OSHA regulates hundreds of air contaminants, including heavy metals and persistent
organic chemicals in 29 CFR 1910.1000, but agricultural operations are exempt. Agricultural
operations are not exempt, however, from the cadmium regulations (29 CFR 1910.1027) limiting
airborne exposure to cadmium during a work shift to 5 |J.g/m3. In addition, the standard
regulating the storage and handling of anhydrous ammonia (29 CFR 1910.111 (a) and (b))
applies to agricultural operations.
4.2.2 EPA Regulations for Hazardous Waste Derived Fertilizers
One of the primary objectives of the RCRA program is to encourage legitimate recycling
of hazardous wastes, while maintaining appropriate regulatory controls to ensure that such
practices are protective of human health and the environment. In the case of fertilizers, current
RCRA requirements address two major environmental concerns: (a) how hazardous waste
secondary materials are managed prior to recycling, and (b) controls on contaminants in the
fertilizer products made from such materials. RCRA generally does not regulate the actual units
or processes that are used in recycling. The following is a summary of the current regulatory
framework for hazardous waste derived fertilizers:
• RCRA regulations currently require that (with one exception) fertilizers made from
recycled hazardous wastes have to meet the applicable "land disposal restrictions"
treatment standards (these "LDR" treatment standards have been developed by EPA
for essentially all hazardous wastes that are land disposed). These standards are
generally technology-based, and are expressed as concentrations in leachate when
tested according to the Toxicity Characteristic Leaching Procedure (TCLP). This
57
-------
leaching procedure was originally developed by EPA to simulate how contaminants
leach from wastes in municipal solid waste landfills.
• The current regulations provide one exemption from having to meet the LDR
treatment standards—fertilizers made from electric arc furnace dust (RCRA waste
code K061) are not required to meet any specific contaminant standards.
• Management of hazardous secondary materials prior to recycling for fertilizers is
subject to the "use constituting disposal" (UCD) provision of RCRA (40 CFR
266.20). This provision in essence requires that hazardous waste secondary materials
must be managed as hazardous wastes prior to being recycled. Thus, for example,
shipments of such materials are subject to manifest requirements, and storage of the
materials (e.g., by the fertilizer manufacturer) will generally require a RCRA permit.
• Certain types of wastes are specifically exempted in the RCRA statute (the so-called
Bevill exemption) from being regulated as hazardous waste, unless EPA establishes
through rulemaking that such wastes should be regulated as hazardous wastes. Thus,
fertilizers made from such exempt wastes (which include mining wastes, and gypsum
from coal-fired power plants) are not subject to RCRA standards, even if the wastes
(or the fertilizer) were to exhibit a hazardous waste characteristic.
4.2.3 Military Munitions Rule: Hazardous Waste Identification and Management;
Explosives Emergencies; Manifest Exemption for Transport of Hazardous Waste on
Right-of-Ways on Contiguous Properties; Final Rule
The Military Munitions Rule (FR, February 12,1997) discusses the recycling of
propellant or explosive as fertilizer. If processed in a manner rendering it suitable for land
application, this is a permissible under RCRA. "Under 40 CFR 266.20(b) commercial fertilizers
that are produced for the general public's use that contain recyclable materials are not presently
subject to regulation provided they meet the treatment standard under 40 CFR Part 268, subpart
D, for each recyclable material that they contain." (page 6629). Chemical agents or munitions
exhibiting a hazardous waste characteristic, or akeady listed as a hazardous waste (40 CFR Part
261), are subject to all applicable regulatory requirements of RCRA Subtitle C.
Currently, recycling of munitions into fertilizers has been demonstrated in the laboratory
on a bench-scale, and in limited pilot-scale validation and demonstration tests. A mobile unit
will be available for military tests by mid-1999, and a larger stationary production facility is
planned (http://www.arctech.com).
4.2.4 Metal Containing Pesticides
Metals can be added to soil from the application of pesticides. There are a number of
pesticide products containing cadmium, arsenic, copper, mercury and other metals. Many of
these products are, however, no longer registered by EPA. Table 4-1 shows the metal-containing
pesticide products that are banned, have restricted use, have been canceled in the Special Review
Process or have tolerances on food crops.
58
-------
EPA Office of Pesticide Programs (OPP) publishes a list of pesticides banned and
severely restricted in the U.S. (http://www.epa.gov/oppfeadl/piclist.html). Table 4-1 shows
pesticides containing metals that have been banned from use or have severely restricted use hi the
United States as of August 1,1997. Pesticides may be banned either by EPA canceling the
registrations or by the registrant (i.e. the manufacturer) voluntarily canceling the registration.
The last remaining use of cadmium chloride was voluntarily canceled hi 1990 during the special
review of cadmium products. All uses were canceled in 1991 (56 FR 14522, April 10,1991).
All registrations of inorganic arsenicals have been canceled except for a few select uses (arsenic
trioxide insecticide and mole/gopher control). Copper acetoarsenite and copper arsenate uses
were canceled hi 1977 (42 FR 18422, April 7,1977). Uses of mercury as an antifouling agent hi
paint were'cahceled hi 1990 for indoor paint (55 FR 26754, June 29,1990) and hi 1991 for
outdoor paint (56 FR 105, May 31,1991).

Table 4-2 contains a list of metal-containing pesticides for which there is at least one
tolerance set on food crops (i.e. these pesticides have some agricultural use). There are also a
number of pesticides which are exempt from tolerances on raw agricultural commodities
assuming the products are applied in accordance with good agricultural practices. These
chemicals are too numerous to mention but consist of many pesticides that contain plant
micronutrients. For example, many copper, magnesium and zinc salts and boric acid are listed in
40 CRF SubpartD Section 180.1001 - 1164 as exempt from tolerances.

-------
Although most of the highly toxic pesticide products (i.e. those containing mercury,
cadmium and arsenic) have been banned, there are still pesticide products which have the
potential for adding metals to soils and plants. Many of these pesticides contain metals which
are also considered plant micronutrients.
4.2.5 Radon in Phosphogypsum
The National Emission Standards for Hazardous Air Pollutants (NESHAP) for radon
regulates radon emissions from phosphogypsum stacks (40 CFR Part 61, Subpart R). The
regulation allows phosphogypsum to be removed from phosphogypsum stacks for agricultural
purposes if the radium-266 concentration is determined annually and does not exceed 10
picocuries per gram (pCi/g). EPA analyzed the potential risks associated with long-term use of
phosphogypsum in agriculture to set this limit. The Fertilizer Institute filed a petition on August
3,1992 to reconsider this revised rale. The changes that EPA is considering do not, however,
affect the concentration limit of 10 pCi/g.
4.3. INTERNATIONAL FERTILIZER REGULATIONS
International fertilizer regulations differ in their content and in enforcement. The
regulations for Canada and Japan contain requirements limiting concentrations of heavy metals
and, in the case of Japan, organic chemicals in fertilizers. Regulations for the European Union
(EU) are also discussed because these directives must be followed by all EU countries.
4.3.1 Canadian Fertilizers Act and Regulations
The Canadian Fertilizers Act R.S., c. F-9, s.l (1993) and Fertilizers Regulations contain
metal limits used by the Canadian Food Inspection Agency to regulate all fertilizers and soil
supplements sold in Canada. Although these limits were not based on quantitative risk
assessments, the Trade Memorandum T-4-93, August, 1996 from the Food Production and
Inspection Branch states that these limits:
"..were developed to help ensure that fertilizers and supplements continue to pose only a
minimum risk of adverse effects due to metal contamination... The AAFC metal
standards are based on generic principles and are generally applicable to fertilizers or
supplements applied to land or in crop protection."
Although the metal limits were originally written for the land application of biosolids, these
limits now apply to all fertilizer products. Metal limits were developed by the Ontario Ministry
of Agriculture and Food in 1978. These limits were revised and adopted by Agriculture Canada
for application to biosolids and similar products in 1980. Table 4-3 shows the limits for metals
in fertilizer and soils following application of fertilizers as stated in Trade Memorandum T-4-93
(August, 1996). Agriculture and Agri-Food Canada is considering limits for two additional
metals, chromium (210 kg/ha) and copper (150 kg/ha). These limits have not yet been
implemented.
The Canadian government enforces metals regulations for fertilizers by requiring all
micronutrient fertilizers, fertilizer/pesticide mixes, and most supplements to be registered
61
-------
through the Canadian Food Inspection Agency (CFIA). For a product to become registered, the
manufacturer must submit metal analyses of its product, and the levels must be below the
Canadian limits. Non-registered fertilizer products are subject to marketplace monitoring, in
which products are randomly selected by the CFIA for metal analyses. If the CFIA finds a
product on the market that exceeds the Canadian limits on metals, it has the powers of detention
and seizure of the product. More information about Canada's Fertilizers Regulations can be
found on the internet at http://www.dfia-acia.agr.ca/enghsh/actsregs/fert/fertrege.html.
The Canadian limits shown in Table 4-3 require some additional explanation. The
Maximum Acceptable Cumulative Metal Additions to Soil (kg/ha) pertain to additions over a
long term. For the purposes of this calculation, "long term" is taken to mean 45 years. In
comparisons made in Section 5 of this report, these values were divided by 45 to more closely
approximate annual limits. The Maximum Acceptable Metal Concentrations (mg/kg dry weight)
in the fertilizer product were originally developed for biosolids and are based on the assumption
that (Agriculture and Agri-Food Canada, Food Production and Inspection Branch, Trade
Memorandum T-4-93, August, 1996):
"A cumulative total application to soil of 200 dry tonnes per hectare of a product that
contains 50% moisture and a total N guarantee of 2.5% (i.e. 5% nitrogen on a dry weight
basis). Such a product, applied annually at a rate of 220 kg N/ha (or 4,400 kg dry
product/ha) would reach the standards for maximum acceptable cumulative metal
additions to soil within 45 years"

-------
In addition:
"Acceptable metal concentrations increase as the rate of application decreases relative to
4400 kg dry product/ha (e.g. if the rate of application is 2200 kg dry product/ha, this is
half 4400 kg therefore the metal concentrations can be double the [maximum acceptable
metal concentrations (mg/kg dry weight)]. Or, when products are applied on the basis of
theur nitrogen content, acceptable metal concentrations increase proportionally with total
%N on a dry weight basis"
Additional explanation for estimating the maximum acceptable metal concentrations (mg/kg dry
weight) may be found in the Trade Memorandum T-4-93.
Trade Memorandum T-4-112 (April 1994), Information Required for the Assessment of
By-Products and Other "Waste" Materials Sold as Fertilizers or Supplements, provides for pre-
market assessment of specific end-use product types (e.g., micronutrient fertilizers, supplements,
soil amendments, wetting agents, and microbial innoculants) and other products if there is a
cause for concern. This assessment addresses issues of safety, labelling and efficacy. It requires
identification and description of the product and its constituents, identification of the industrial
process from which the product is derived, the benefits of the product, rates and methods of
application, and documented analyses for heavy metals, dioxins and furans.
The selection of specific product types for assessment is reviewed in an information
source for the inspection's staff, entitled "Regulation of Recycled Material and By-Products
Under the Fertilizers Act". This information source was drawn up as a guide, and was not
intended to be inclusive of all potential recycled by-products, nor representative of current or
actual practices. As listed in that source, examples of industrial by-products, and the chemicals
these products may contain, are:
1. Baghouse/flue dust (heavy metals including, iron, zinc, manganese and
molybdenum),
2. Cement kiln dust (potassium, calcium, sulphur, iron, magnesium, aluminum, and
PAHs),
3. Coal fly ash (aluminum, silicon, iron, calcium, potassium, sodium, arsenic
molybdenum, selenium and PAHs),
4. Galvanizing fluid (zinc, iron and other heavy metals),
5. Gypsum (calcium sulfate and traces of dioxins, furans and boric acid),
6. Bauxite mine tailings (aluminum, dicalcium silicate),
7. Newsprint (heavy metals, PAHs),
8. Phosphogypsum (gypsum, fluoride),
9. Pulp and paper sludge (a variety of organic and inorganic substances),
10. Smelter slag (heavy metals, magnesium, calcium),
11. Waste lime (calcium, magnesium, cyanides and sulfites).
4.3.2 Japan
Japan regulates incinerator ash from both industrial and municipal waste treatment
incinerators. Sludge ash is used for soil improvements. The standards for organic and inorganic
63
-------
chemicals in incinerator ash are shown in Appendix E, International and National Limits for
Pollutants in Biosolids, because these limits apply to the leaching of chemicals from incinerator
ash produced from burning sewage sludge. These values are from the Prime Minister's Office
Ordinance for Establishing Evaluation Standards Regarding Industrial Wastes, including Metals
(1995).
4.3.3 European Union
The European Union Directive, Council Directive On the Approximation of the Laws of
the Member States Relating To Fertilizers (76/116/EEC) sets forth the regulations regarding
"straight and compound" fertilizers. The directive is similar to the AAPFCO model document in
that it describes only the fertilizer content and package markings. Member states may adapt this
regulation. Fertilizer marketed as "EEC fertilizer" is subject to official control measures to
assure compliance with the declared nutrient content. Subsequent directives have added fertilizer
types to the Annex I (N, P and K) and Annex n (Secondary nutrient Fertilizers) of this directive
and tolerances for specific components to Annex HI. For example, Urea-ammonium sulphate,
0.5% was added to all three Annexes in a Commission Directive of May 10,1996 (96/28/EC).
The EU Council Directive of 12 June, 1986 (86/278/EEC) describes the use of sewage
sludge in agriculture. The limits for metals are described in the following section and in
Appendix E, Table E-l International Contaminant Concentration Limits for Biosolid Application
to Land
The Council Directive of 12 December, 1991 (91/689/EEC) replaces the previous
Council Directive of 20 March, 1978 (78/319/EEC) on disposal of dangerous waste. This
directive defines waste, requires that discharges be identified and recorded, transportation and
storage be inspected and controlled and that establishments responsible for disposal and recovery
of wastes on behalf of third parties be identified to the Commission. Annex I of this directive
identifies categories of hazardous waste. Annex E lists the chemical constituents of wastes and
Annex IH identifies the properties of wastes which render them hazardous. In simplified form,
this regulation is similar to those of U.S. EPA.
The reuse of materials is encouraged in a non-obligatory council directive of 18 March,
1991. Member states are encouraged to become self-sufficient in waste disposal, and the Council
discusses the desirability of adopting specific rules on recovered waste. Article 4 states:
"Member States shall take the necessary measures to ensure that waste is recovered or
disposed of without endangering human health and without using processes or methods
which could harm the environment."
Annex HE lists operations which may lead to recovery and describes the RIO recovery method:
"Spreading on land resulting in benefit to agriculture or ecological improvement,
including composting and other biological transformation processes..."
This directive does not, however, provide any guidance on limits of contaminants in the
environment.
64
-------
4.3.4 Cadmium in Fertilizers
Rock phosphates contain cadmium as a trace element (See Table 3-5). Because of the
concern about the toxicity of this element and the need for application of phosphate fertilizers, a
number of countries have standards and guidelines limiting the cadmium content of fertilizers
and soil. Table 4-4 presents a number of these limits for countries around the world. Most of the
limits are stated as a weight of cadmium per weight of phosphorus or phosphate in the fertilizer.
In some cases, the cadmium limits are for the total fertilizer weight. Belgium has the lowest
limit for all fertilizers, 2.5 mg/kg dry weight, and the Netherlands has the lowest limit for
compost and "very clean" compost, 1.25 mg/kg and 0.7 mg/kg, respectively. Cadmium limits in
biosolids applied to land are discussed in the next section.
4.4. BIOSOLIDS APPLICATION TO LAND
4.4.1 EPA 40 CFR Part 503 Standards for the Use or Disposal of Sewage Sludge
The U.S. EPA regulates use and disposal of biosolids via 40 CFR Part 503, "Standards
for the Use or Disposal of Sewage Sludge." In this regulation, EPA sets limits for certain metals
in biosolids when applied to agricultural land. These limits are summarized in Table 4-5.
Concentrations limits for nine inorganic (metal) pollutants hi the sewage sludge and for the soil
following application of the sewage sludge are included in the regulation, hi addition, hi May
1993, EPA prepared a list of 31 potential pollutant candidates to be included in the regulation.
These pollutants were selected based upon the frequency of detection in the 1988 National
Sewage Sludge Survey. Based on screening risk assessments, EPA is scheduled to propose (by
March 1999) comprehensive numerical standards and appropriate management practices for
biosolids. These will apply to all use and disposal practices, including land application, surface
disposal, and incineration, and will encompass limits for dioxins/furans and coplanar PCBs. A
final rule is anticipated by 2001.
Many individual states include several limits for other metals. Appendix E presents
limits for metals in biosolids for Pennsylvania and the New England states. Many of these limits
are the same or lower than those in the Section 503 rule. All the states listed have limits for
chromium (which was deleted from Part 503 rule based on a court decision). Connecticut has
additional limits for chromium (VI) and barium.
4.4.2 International Biosolids Regulations
Inorganic and organic concentration limits in sludge and soils following land application
are presented hi Appendix E. These values have been abstracted from A Global Atlas of
Wastewater Sludge and Biosolids Use and Disposal (1996) for 15 countries and the European
Union. Canadian regulations for biosolids application to land are the same as for any fertilizer
(see Table 4-2). All these countries regulate metals (cadmium, chromium, copper, lead, mercury,
nickel and zinc) in biosolids and most regulate arsenic. It is difficult to determine which country
has the most conservative limits because they vary by metal; however, the Netherlands and the
Scandinavian countries generally have the lowest limits.

a) The ceiling concentrations and monthly average concentrations are limits for pollutants in the sewage
sludge product, not the soil
Some countries also regulate other inorganic chemicals (e.g. molybdenum, boron,
selenium) as well as some organic chemicals. For example, Australia sets limits for pesticides in
sludge and soil, China regulates mineral oil and Austria regulates persistent organics. Japan
applies the same standards for industrial waste to biosolids waste because biosolid sludge is
incinerated and these incinerators are considered industrial plants and must meet the
environmental regulations for industry. Japan has limits for many organic and inorganic
compounds as the extractable solution in the waste.
4.5 SUMMARY OF REGULATIONS
Canada specifically regulates nine metals in all fertilizers. Certain European countries
and Australia regulate cadmium in phosphate fertilizers. Japan regulates metals and some
organic chemicals in incinerator ash that is applied to agricultural land. The U.S. regulates
fertilizers that are made from hazardous waste by setting limits for certain metals in those wastes
before the waste or product containing the waste can be applied to the land.
States regulate fertilizers, generally through the state agriculture departments. Most
states have fertilizer regulations similar to the AAPFCO Uniform State Fertilizer Bill shown in
Appendix D. These bills generally regulate plant nutrient and efficacy claims made on the
product labels. States (and AAPFCO) have recently begun to also adopt specific standards for
contaminants in fertilizers.
There are international, national and state regulations for the application of sewage sludge
(biosolids) to land. These laws and regulations have specific limits for toxic metals in sludge and
frequently include limits for metals in the soil following application of biosolids.

5.0 CHARACTERIZATION OF ADDITION OF METALS TO SOILS AS A RESULT OF
FERTILIZER APPLICATION - COMPARISON TO REGULATORY LIMITS
This section combines information from Section 2 on fertilizer consumption, Section 3 on
metals in fertilizers and soils and Section 4 on regulations for metals in fertilizers and soils.
First, we describe the assumptions necessary for the calculation of metal additions to soil
following fertilizer application. Next, application rates for N, P and K fertilizers and
micronutrients are combined with information on metal concentrations in these products to
determine potential soil additions of metals resulting from fertilizer use. Then we compare these
values for metals in fertilizers and soils to the available regulatory limits. The fourth part of this
section describes questions that have arisen and data gaps identified in the characterization of soil
contamination following application of fertilizers which contain non-nutritive heavy metals.
Note that at this time, only the changes in soil concentrations from metal additions are
considered. This report does not attempt to evaluate the impacts of these soil additions on human
health or the environment.
This section addresses the following questions:
• What do we know about trace-metal contamination of fertilizers and the resulting
application to soils?
• Based on simplifying assumptions, what concentrations of metals in soil might be
expected following fertilizer application?
• How do these levels compare to national and international standards and guidelines?
• Based on typical fertilizer application rates, how long will it take to double soil
background contaminant levels?
• What additional information is necessary to thoroughly characterize the extent of soil
contamination following fertilizer application?
5.1 ASSUMPTIONS FOR THE CALCULATION OF METAL SOIL LOADINGS RESULTING
FROM FERTILIZER APPLICATION
A number of assumptions must be made to calculate the annual addition of metals to soil
(mg/kg or kg/hectare = kg/ha) following fertilizer application. Data from Section 3 listing metal
contaminants in various fertilizers have been combined with typical application rates for fertilizer
products. The basic equation for the calculation of metal addition to soil (mg/kg) is:
mg X _ mg X x 1 kg product
kg soil kg product (% 7/100) kg a.i.
kg a.i ha
ha 2,000,000 kg soil
(1)
where: X = metal contaminant
Y = fertilizer nutrient (e.g., zinc, nitrogen, P2O5, K2O)
AR= application rate (kg/ha)
a.i. = active fertilizer ingredient (e.g. nitrogen, N)
69
-------
The value 2,000,0000 kg soil/ha is calculated based upon an assumed soil density of 1.33 g/cm3
using the following equation:
1,995,000
100 m x 100 m x Q.15 m x 1.33 (g/cm3)
ha
ha
=-2,000,000
ha
0.01 (m/cm)3
(2)
This assumes that the soil density is 1.33 g/cm3 (US EPA Office of Wastewater Management,
1995; Foth, 1990; Manrique and Jones, 1991; US EPA, 1997a) and that the soil plow depth is 15
cm (0.15 m) (Rothbaum et al., 1986). (Note that the soil density, or bulk soil density, is the mass
of oven dry soil per volume sampled, and thus includes both the soil particles and the interstitial
air.) A hectare is 10,000 m2. The yearly addition of contaminant X to the soil (kg X/ha) is
calculated:
mgX
1 kg product
kgX = _
ha kg fertilizer product (% 17100) kg a.i.
kg
kg a'LY
ha 1,000,000 mg
(3)
Some limits for metals in soils are reported on a mg/kg basis. To convert from kg/ha to mg/kg,
multiply the value of the contaminant hi kg/ha by 0.5:
mgX
kg soil
_ kgX
ha
ha 2,000,000 kg soil
1,000,000 mgX = Q5 kgX
IkgX 'ha
(4)
The applications to soil are calculated per crop year; that is, application rates used in the tables
may result from multiple applications of a single product in a single growing season. But we
have not considered applications of several fertilizer types during a crop year since that
information is not available at this time.
5.2 SOIL CONCENTRATIONS OF METALS FOLLOWING APPLICATION OF ISI. P AND K
FERTILIZERS AND MICRONUTR1EMT FERTILIZERS
Although there are considerable data on concentrations of metals in fertilizer products, the
data are neither comprehensive nor representative of all fertilizer types. For example, analyses of
metals in 141 different NPK, 61 phosphate and 63 zinc fertilizer samples were available for
these comparisons. In contrast, analyses of only 2 or 3 boron, iron, magnesium, and manganese
fertilizers were available. In addition, the 141 NPK samples (and all other fertilizer samples, as
well) were typically not characterized with respect to all 9 metals compared in this report. The
most frequently analyzed/reported metals included Cd, Pb, As, and Zn. Data on Hg
concentrations hi fertilizer products are somewhat limited by analytical method detection limits
(i.e., samples were analyzed, and concentrations were reported as less than a detection limit that
is substantially higher than concentrations at which Hg was detected in other samples). The
application rates are chosen to cover a range of potential values.
70
-------
The application rates for N, P, and K fertilizers, micronutrient fertilizers, lime and
gypsum used for calculations here are summarized in Table 5-1 (N, P, and K) and Table 5-2
(micronutrient, lime and gypsum). The N, P, and K fertilizer application rates are taken from the
USDA/NASS database and reflect rates applied to six field crops (1996 crop year), the eight
vegetables with more than 100,000 planted acres in one type (cucumbers not included because
neither fresh nor processed type alone exceeded 100,000 planted acres) (1994 crop year) and the
six fruits with more than 100,000 planted acres (1995 crop year). The six field crops include
corn, cotton, potatoes, soybeans, tobacco and wheat; the eight vegetable crops include snap
beans, broccoli, carrots, corn, lettuce, onions, peas and tomatoes; the six fruit crops include
watermelons (listed in the USDA/NASS database under vegetables), oranges, grapefruit, apples,
grapes and peaches. (Note: These 20 crops were selected for subsequent calculations in this
report because they account for a large majority of the crop acreage planted in the U.S. each
year.) The USDA/NASS database lists fertilizer application rates separately for the three types of
wheat (winter, durum and spring). For this report a single, aggregate application rate for wheat
was developed, and used, which consisted of the acreage-weighted rate for the three types of
wheat. In a similar manner, single acreage-weighted rates were also developed for snap beans
(fresh and processed), corn (fresh and processed), and tomatoes (fresh and processed). The N, P
(P2O5), and K (K2O) fertilizer application rates for these crops (6 field, 8 vegetables, 6 fruit) are
summarized in Appendix Table F-l. Six different global application rates were considered
initially for N, P, and K application rates, and these rates are listed at the top of Table 5-1. The
three selected application rates for all subsequent calculations are listed at the bottom of Table
5-1. The 6 application rates considered initially included: the maximum rate cited for these crops
(max of range); the 19th highest average application rate for the 20 crops selected (95th
percentile), the 16th highest average application rate for the 20 crops selected (80th percentile),
the average of the top 10 average application rates (avg top 10); the average of all average
application rates (avg avg); and the average of all average application rates weighted by the
number of acres planted in that crop (avg acre weighted). (Note: The 19th and 16th highest
average application rates are unbiased non-parametric statistical estimates of the 95th and 80th
percentile average application rates, respectively; seeDudewicz, 1976.)

-------
As shown at the bottom of Table 5-1, the average of all average application rates was
selected to represent an "average" application rate; the 19th highest average application rate for
the 20 crops (95th percentile) was selected to represent a "high" application rate; and the
maximum rate cited for these crops (max of range) was selected to represent a "maximum"
application rate. The maximum application rates were used on watermelon, lettuce and tomato
crops, for N, P, and K respectively. The 95th percentile application rate (high) was the rate
applied to broccoli, potatoes, and oranges for N, P, and K respectively.
The Food and Agriculture Organization of the United Nations (FAO) has published
world-wide application rates for several additional crops such as peanuts, barley, oats, rye,
sunflower, sugar beets, sugar cane, and pasture lane (FAO, 1996). These application rates are
based on estimates by experts in the field as opposed to recorded measurements documented in
the USDA/NASS database. However, they could be used to supplement the survey data from
USDA/NASS that is used hi this report. Based on the U.S. data from the FAO, the average
application rates are 34 Ib/A for nitrogen fertilizers, 18.7 Ib/A for P2O5 fertilizers, and 44.4 Ib/A
for K^O fertilizers for peanuts, barley, oats, rye, sunflower, sugar beets, sugar cane, and pasture
land. Pasture had the lowest application rates for all three fertilizers at 4.5,1.8, and 1.78 Ib/A for
nitrogen, P2O5, and K2O fertilizers respectively. The high application rates are 93 Ib/A for sugar
beets, 44 Ib/A for peanuts, and 220 Ib/A for sugar cane for nitrogen, P2O5 and K2O fertilizers
respectively. Although the data from the FAO were not used in these calculations of application
rates in Table 5-1, the application rates from the FAO fall within the ranges of the application
rates that were used.
The average, high and maximum secondary nutrient, micronutrient, lime and gypsum
application rates are listed in Table 5-2. These rates were derived from interviews with experts in
the area, including leading scientists with the agricultural extension services at 7 states, and from
Table 5-2. Secondary Nutrient, Micronutrient and Lime Application Rates (Ibs/acre) Used in

information published by agricultural extension services on the Internet for 8 states. Agricultural
extension agency scientists and leading professionals were contacted in CA, OR, WA, AL, OH,
NY and NB. Data were obtained from Internet sites for extension services in the following
states: NB, MN, GA, AL, FL, IL, MO and TX. The data obtained from these interviews and
searches are listed in Appendix Table F-2. Due to the more limited nature of these data
compared with the extensive USDA/NASS database, the average and high application rates were
selected as best estimates from these searches; the maximum application rate was the highest rate
quoted or listed by any agricultural extension service.
The yearly average additions of metals to soil (kg/ha) were calculated for each fertilizer
product using Equation [1]. These calculations are tabulated in Appendix G of this report for:
P2O5 fertilizers: Tables G-l(a-e),
NPK fertilizers applied for P2O5 content: Tables G-2(a-e),
NPK fertilizers applied for N content: Tables G-3a-e),
Potash (K2O) fertilizers: Tables G-4(a-e),
Zinc (Zn) fertilizers: Tables G-5(a-d),
Manganese (Mn) fertilizers: Tables G-6(a-e),
Boron (B) fertilizers: Tables G-7(a-e),
Iron (Fe) fertilizers: Tables G-8(a-e),
Sulfur (S) fertilizers applied for nutrient content: Tables G-9(a-e),
Sulfur fertilizers (S) applied for pH adjustment: Tables G-10(a-Oe),
Liming Materials: Tables G-ll(a-e),
Gypsum: Tables G-12(a-e), and
Micronutrient mixes: Tables G-13(a-e).
Important Note:
For these calculations, each product-specific metal X level (mg X/kg of product) and the
product-specific concentration of active ingredient (e.g. 20% zinc fertilizer = 0.2 kg a.i./kg
product) were combined with the three global application rates for average, high and maximum
application of active ingredient (Equation [3]), to obtain an average, high and maximum yearly
addition of each metal for that specific product. At the conclusion of each table is listed the
average yearly metal addition from all products, as (or if) applied at the average, high and
maximum application rate. In addition, in Appendix G the product which produces the highest
yearly addition of the specific metal being characterized is shaded for visual identification.
As indicated in Equation [3], the yearly addition of metal to soil is determined by both the
level of the metal in the product and the level of the desired nutrient. A fertilizer product can
contribute high levels of heavy metals to soil when the heavy metal concentration in the product
is high and/or when the desired plant nutrient is at a low level in the product. For example, one
lime product had CaCO3 content of only 7.6%. Although the Cd concentration in this product
was comparable to levels in other lime products, the calculated addition of Cd to soil was high,
due to the low nutrient content. For this report, soil metal addition rates for each product were
calculated, and then the average soil metal addition rate from all products of a fertilizer category
was calculated. The average product of each fertilizer category is defined here as that product
which would give the average soil addition rate of a given metal.
73
-------
The fertilizer products that were analyzed in this way are those reported in Section 3,
Tables 3-6 though 3-11, with some exceptions. Exceptions include those products for which the
active ingredient percentage was not identified (e.g., Table 3-9 samples), the single magnesium
fertilizer sample identified (Table 3-8), and the organic and/or biosolids fertilizers (Table 3-7).
Inasmuch as this report was designed to evaluate only the inorganic fertilizers, the organic
fertilizers and/or soil amendments (sewage sludge, humus, compost, tankage, etc.) were not
carried through this set of calculations. Those NPK fertilizers that were clearly identified as
being "biosoUds-based" were also eliminated from these calculations. In addition, soil
amendments, potting soils, and "soil conditioners" were not carried through this set of
calculations, this due in part because application rates were not fully characterized.
Tables 5-3a through 5-8a provide the summary of the average metals soil additions (kg/ha
soil) that may result from average, high and maximum application rates of inorganic fertilizers,
gypsum and lime. Tables 5-3b through 5-8b provide the summary of the average, high and
maximum soil metal contaminant levels resulting from the individual products in each fertilizer
category which give rise to the highest calculated soil loadings with the global average, high and
maximum product-specific application rates.
Application of zinc fertilizers (Table 5-3a) at the maximum application rate results in soil
additions of less than 0.1 kg/hectare of all metals except for lead (0.884 kg/hectare). Phosphate
products (Table 5-3 a) at the maximum application rate also result in metal addition to the soil of
less than <0.1 kg/hectare for all metals except chromium (0.1 kg/hectare), vanadium (0.173
kg/ha) and zinc (0.150 kg/hectare). NPK fertilizers applied for N content (Table 5-4a) and
applied at the maximum rate contribute 0.10 kg/ha/year of lead to the soil (Table 5-4a). Boron
and K20 fertilizers (Tables 5-5a and 5-6a) contribute extremely low levels of contaminants,
generally O.001 kg/ha/year at the maximum application rate, with exception of 0.023 kg/ha/year
of arsenic from boron fertilizers. Iron fertilizers contribute almost 0.5 kg/ha/year of arsenic and
1.6 kg/ha/year of lead to the soil when applied at the maximum rate (Table 5-5a). The
manganese fertilizers (Table 5-6a) contribute very low levels of contaminants, with the highest
level contributed by the zinc in the manganese fertilizers at 0.004 kg/ha/year at the maximum
application rate. Adding sulfur to the soil as a nutrient adds 0.18 kg/ha of zinc to the soil; adding
sulfur for pH adjustment adds 0.11 kg/ha of copper to the soil each year (Table 5-7a) at the
maximum application rate. Average additions of zinc and vanadium (0.48 and 0.30 kg/ha,
respectively) are the highest metals additions from gypsum applications (Table 5-8a). Zinc, lead
and copper (at 6.6, 0.69 and 0.63 kg/a, respectively) are the metals added in highest quantities
with liming agents (Table 5-8a).
The data from Tables 5-3(a/b) to 5-8(a/b) are represented graphically in Figures 5-1 to
5-9. As shown in Figure 5-1, the data for Cd additions to soil from the different fertilizer types
are compared, and those individual products which are known to be derived from industrial waste
products are so indicated.
The number of metals analyzed in each fertilizer product varied from as few as one or
two, to the entire suite of nine metals. In Tables 5-3a through 5-8a, the number of samples in
which a Cd concentration was measured is given hi the header information of that table. In
general, Cd was the one metal analyzed most frequently. However, because some of the metals
74
-------
were analyzed far less frequently than Cd, the number of samples, by fertilizer type, which
provided concentration data for each metal have been tabulated (see Table 5-9).
As shown there, the data for several of the metals in several fertilizer types is limited, and this
may significantly affect the accuracy of conclusions drawn about the soil additions of these
metals.
This table provides a listing of the number of products in each fertilizer category for
which metals data were available, and the number of those products which exceeded the
annualized Canadian Fertilizers Regulations limits when applied at the nutrient application rates
chosen here. Note that hi each fertilizer category, metals concentrations were not available for all
products. For example, for the P2O5 fertilizers, Cd levels were listed for 61 products, Pb levels
were given for 58 products, As levels were given for 64 products, and so on. Several of the
metals evaluated here, e.g., Cr, V, and Cu, do not have limits imposed by the Canadian
regulations, and for these metals an accounting of exceedances was not necessary. The
exceedances in Table 5-9 are listed separately in Table 5-10 by the number of products that
exceed the Canadian standards at the average, high and maximum nutrient application rates
evaluated here. For example, in the P2O5 products, the one product that exceeded the Canadian
standards did so only at the maximum application rate. In the NPK products applied for P2O5
content (NPK-P), 5 products exceeded the Canadian standards at the high application rate, and 10
products exceeded the standard at the maximum application rate. One lime product exceeded
standards for 5 of the metals at the average application rate; one NPK-P product exceeded Pb
standards at the average application rate; and one iron product exceeded As standards at the
average application rate.

5.3 ADDITIONAL DATA PROVIDED ON BLENDED PRODUCTS
The inventory of heavy metals additions to soil from NPK fertilizers applied for N
content (NPK-N) was largely supplied by the Pennsylvania Department of Agriculture (PDA).
The PDA measured concentrations of heavy metals in 125 diverse fertilizers during the first half
of 1998. The 125 products tested were selected to represent a cross-section of fertilizer products
distributed in Pennsylvania; 32 were solid NPK formulations for the agricultural market, 20 were
solid NPK formulations with micronutrients for the agricultural market, 35 were specialty
fertilizers for the residential market, 25 were NPK liquid fertilizers, and 20 were primary
ingredients. The concentrations of heavy metals in these samples are listed in Appendix H,
Tables H-l through H-5.
These PDA products differed from the products obtained from other surveys, and only
selected products were readily amenable to inclusion in the calculations of Appendix G of this
report. The 32 solid NPK fertilizer blends were included in the NPK-N (NPK fertilizers applied
for N content) portion of Appendix G for determination of an average addition of metals from this
class of fertilizers. The NPK blends with micronutrients were not used in the NPK category
because the added micronutrients were not specified and their concentrations may have governed
the application rates. The specialty fertilizers were not used in Appendix G, as these were listed
as products for the residential market; many were listed as being either biosolids-based, organic
(e.g., made from fish meal), or blended with micronutrients. The fertilizers listed as "Ag liquid"
had the notation that they were applied to land at much lower application rates than solid
fertilizers. Because of that caveat, and the fact that no typical application rates were available,
these fertilizers were not included in Appendix G of this report. Appendix H of this report,
though, does include a listing of metals concentrations in these sample fertilizers, and may be
used for reference with the data presented elsewhere in the report.
The data provided by PDA provides important insight into the manner in which fertilizers
are now being blended on a custom basis for each farm, soil and crop type. With the proliferation
of rapid soil nutrient testing procedures, and computerized calculations of nutrient need vs
available nutrient, it is clear that blending of products on a case-by-case basis provides the
optimal fertilizer for each application. This customization, though, means that from a survey
perspective, it may be very difficult to ascertain the broad range of formulations and application
rates that are being used across the country.
In general, the range of metals concentrations in the fertilizers that are found in these
PDA samples are similar to the range identified from other studies. The solid NPK ferilizers
blended with micronutrients tend to have higher levels of copper, lead, mercury and zinc than that
found in the straight NPK blends. Inasmuch as the micronutrient fertilizers tend to have higher
metals levels than the NPK fertilizers, it is apparent that the higher levels of heavy metals in the
NPK/micronutrient blends are probably due to the added micronutrients. The specialty fertilizers
for the residential market, in some cases, also had higher than average levels of copper, lead,
mercury and zinc. Presumably, these fertilizers either are biosolids-based or contain
micronutrients.
The NPK blends were compared for the metal addition rates that would result from
application of the product according to either the N content, the P2O5 content, or the K2O content.
98
-------
The data for individual products are listed in Appendix H, Tables H-6 through H-10. The
summary statistics for these comparisons are listed in Appendix H Table H-l 1. The summary
statistics include the mean, median and range of soil metals additions for the NPK products, when
applied for either N, P or K content at the average, high or maximum application rate. As shown
there, application rates used according to N content result in the highest soil loadings of the heavy
metals, relative to the P2O5 and K2O application rates. The average of all the NPK products,
applied at the highest N application rate, is, in all cases, lower than the Canadian Fertilizer Acts
limits for annualized additions for cadmium, lead, arsenic, copper, zinc and mercury.
5.4 COMPARISON OF METAL CONCENTRATIONS IN SOIL TO NATIONAL AND
INTERNATIONAL STANDARDS
The Canadian Fertilizers Act, described in Section 4.3.1, and the 40 CRF Part 503
Biosolids Standards (Section 4.4.1) may be used for comparison to the values presented in section
5.2 for metal addition to land from fertilizer application. Although the biosolids regulation may
not be appropriate because we have not considered metal availability, soil type, and soil and
organic matter content, these values provide a guideline for the comparisons. The Canadian
Fertilizers Regulations specifies limits in terms of the maximum acceptable cumulative metal
addition to soil (kg/ha) and the maximum acceptable metal concentrations in fertilizer products
(mg/kg dry weight). Since the Canadian regulations for the maximum acceptable cumulative
additions to the soil are long-term standards (45 years), these contaminant limits have been
divided by 45 for comparison to the calculated values and to the U.S. biosolids annual pollutant
loading rates in Tables 5-3a to 5-8a. The biosolids rule presents the annual pollutant loading rate
for land (kg/ha/year) and the ceiling concentration for land application (mg/kg product). The soil
values can be used for comparison to the concentrations calculated in Section 5.2 (kg/ha). We
have assumed that the application rates are for a yearly basis (i.e., may combine multiple
applications of a single product), but we have not considered simultaneous application of several
fertilizer types.
The U.S. biosolids annual pollutant loading rate for land application (kg/ha/year) range
from 0.85 for mercury to 140 for zinc. Comparison of these values to those hi Tables 5-3a to 5-
8a show that even based on the worst case assumptions, additions of metals to soil for the
averaged fertilizers presented in Appendix G are generally two orders of magnitude lower than is
specified in the biosolids regulation. When compared to the Canadian limits (divided by 45 to
approximate annualized pollutant loading rates), only two fertilizer averages exceed the limits:
arsenic from iron fertilizers and arsenic from liming materials exceed the limit when these
products are applied at the maximum application rate. Based upon the maximum application rate
and the contaminant levels from the individual products in each fertilizer category which give rise
to the calculated highest soil loadings for each metal (Tables 5-3b to 5-8b), six fertilizer products
exceed the Canadian Fertilizer Act limits for at least one metal: cadmium and lead in zinc
fertilizers, cadmium in phosphate fertilizers, cadmium, arsenic, and lead in NPK fertilizers
applied for P content, zinc in NPK fertilizers applied for N content, lead and arsenic in iron
fertilizers, and lead, arsenic, mercury, nickel and zinc in liming materials.

5.5 COMPARISON OF FERTILIZER AGRONOMIC PRACTICES WITH BACKGROUND SOIL
METAL CONCENTRATIONS
The calculated yearly additions of metals to soils (mg/kg of soil) due to each fertilizer
class (Tables 5-3 to 5-8, a and b) were combined with the average (geometric mean) background
soil metals levels to estimate the number of years of continuous applications that would be
required for the doubling of background soil metals concentrations (Mortvedt, 1987). There is
not necessarily any human health or environmental consequence from a doubling of the soil metal
background level. Potential human and environmental effects depend upon many factors that are
not considered in this report. The calculation of the number of years to double soil contaminants
is, however, a method for comparing increases of contaminant levels in soils resulting from
application of different types of fertilizers at different application rates. The number of years to
double the background level is obtained by dividing the background soil level by the yearly soil
addition rate. This approach assumes that there is no plant uptake of the metals (or that metals
taken up are returned to the soil when stems, leaves, roots, etc, are returned to the field), that
metals are not lost from the top 15 cm of soil via runoff, wind-borne resuspension, and/or
percolation and leaching into lower depths of the soil, and that wet and dry atmospheric
deposition of metals do not increase soil background levels. The latter assumption neglects
recent work (e.g., Johnston and Jones, 1992), which concludes that atmospheric deposition of
cadmium has been a significant source to soil, leading to an increase in some areas of 30-50% in
the top 23 cm of soil over the last 100 years.
The results of years to double soil background presented in Tables 5-1 la and 5-1 Ib are
based on the assumption that the fertilizers contain average contaminant concentrations and are
applied either at the average (Table 5-1 la) or the maximum nutrient application rate (Table 5-
1 Ib). Tables 5-12a and 5-12b use the single highest product metal addition rate with either the
average (Table 5-12a) or the maximum (Table 5-12b) nutrient application rate.
Those fertilizer applications where soil background levels are doubled in 45 or fewer
years have been shaded for visual identification. The choice of 45 years has no particular
environmental or human health consequence, but was chosen because of the manner hi which the
Canadian Fertilizers Regulation limits are defined. The years to double soil metals levels from
lime applications was calculated on the basis of the liming being done only once every 3 years.
All other nutrients were calculated on the basis of a yearly addition.
Cadmium is the metal most likely to double in soil levels in less than 45 years, followed
by lead, arsenic and copper. Several scenarios evaluated here indicate that mercury and zinc soil
levels may double in less than 45 years with the application of lime products. Mercury additions,
though, may be lost due to volatilization. Application of liming materials is most likely to cause
soil metal concentrations to double in less than 45 years, and several of the products likely to
cause this rise in soil metals are recycled industrial wastes.
Background soil metals levels are doubled in less than 10 years when the single product
which gives the highest yearly addition to soil is applied at the average nutrient application rate
for the following combinations of metal and fertilizer product: Cd from zinc, P2O5 and NPK-P
fertilizers; Pb from NPK-P fertilizers and liming materials; and Zn from liming materials.
Background soil metals levels are doubled in less than 10 years when the single product which

gives the highest yearly addition to soil is applied at the maximum nutrient application rate for the
following combinations of metal and fertilizer product: Cd from zinc, P2O5, NPK-N, NPK-P, iron,
sulfur (as nutrient), and lime products; Pb from zinc, NPK-N, NPK-P, iron, and lime products; As
from iron and lime products; Hg from lime products; Cu from NPK-N and lime products; and Zn
from NPK-N and lime products.
The estimates for doubling of the Hg background are limited to a great degree by the
sensitivity of analytical methods used. Wherever analyses were carried out but Hg was not
detected, one half the detection limit was used as the estimate of the Hg level. This approach may
overestimate the levels of Hg in the fertilizer products. This approach may then result in an
underestimate of the number of years required to double soil Hg levels.
5.6 ASSUMPTIONS, DATA GAPS AND QUESTIONS FOR FURTHER INVESTIGATION
In the process of performing the calculations on metal additions to soil following fertilizer
application and comparing these values to appropriate standards and regulations, a number of
assumptions had to be made.
Simplifying assumptions used for the calculations presented in Section 5.3 were:
Fertilizer application rates chosen for the calculations in this report are for
agricultural crops only. Fertilizer application rates for non-agricultural land (e.g.,
residential and public land), have only a limited amount of information. The variety
of ornamentals, turf and garden vegetables requiring fertilizers and the variety of soil
types makes it difficult to obtain specific data such as that available from the USDA
for agricultural crops. Preliminary data on heavy metals in home garden fertilizers
suggest that significant amounts of metals may be added to home gardens from use of
some of these products.
• Metal additions to the soil were based on application of a single fertilizer type, and a
single crop per year. In fact, many different fertilizers and liming materials may be
applied to a field in a growing season. The concomitant addition of heavy metals
from all sources was not assessed here.
• Calculations of heavy metal additions to soil from fertilizers were based on all
available data. The representativeness of this data set with respect to all fertilizers is
not known. There has not yet been a systematic investigation of all fertilizer types, or
an investigation of the percentage of recycled industrial waste products with
substantial levels of heavy metals in the fertilizer market.
• In only a few instances was the origin (e.g., natural ore or industrial by product) of
the fertilizer product known. Although it may be instructive to compare heavy metal
additions to soil from natural ores and products from industrial waste, such an
exercise could not be undertaken on the basis of the available data.
• To simplify calculations, soil type and chemical nature, plant uptake, leaching and
erosion were not considered in these calculations. All input of heavy metals was
105
-------
assumed to remain with the soil, and this may result in an overestimate of soil metals
levels over a long time period.
The following list presents some areas where data are lacking, and questions remain for further
investigation.
Nationally-representative micronutrient application rates. Aggregate average
application rates for micronutrients and liming materials by state, treated acres and
crop type have not been assembled, as has been done for N, P and K fertilizer.
• Regional variability hi concomitant use of NPK, micronutrient and liming materials
on the same field. Statewide use data for each fertilizer type are available, but the
overlap in application by crop has not been compiled. Some areas of the U.S. may
receive higher input of heavy metals from fertilizers due to the combination of crop
type and existing soil conditions.
• Contribution of fertilizer products derived from industrial wastes to total fertilizer
market. While sources of industrial waste-derived fertilizers are fairly well known,
the market share of these products in the total fertilizer market is not known.
• Nationally representative metal contaminant levels of all fertilizer types. Only a few
studies exist that have measured contaminant levels in fertilizers, and these studies
tend to represent either a single product type and/or products found in a specific state.
Levels of other contaminants such as radionuclides and persistent organic chemicals
in fertilizers and liming materials. Compared with the data on heavy metals in
fertilizers, relatively little information exists on the levels of organic pollutants in
fertilizers. Organics include dioxins, PCBs, pesticides and PAHs.
The environmental fate of chemical additions to soil. This issue has been studied
primarily for cadmium and lead, and most often under controlled laboratory or field
conditions. All potential contaminants, soil types and crops have not been addressed.
In addition, the fate of metals added to the soil as a result of fertilizer addition to non-
agricultural land (e.g., range land and residential land) has not been adequately
studied.
5.7 SUMMARY
Calculations of the additions of metals to soils from different fertilizer applications has
been carried out here, but the interpretation of the data remains limited, due in part to the fact that
few regulations exist that can be used for comparisons. It is unclear whether the U.S. biosolids
standards are appropriate for comparison to inorganic fertilizer types because of differences in
metal availability to the plant, organic matter content and plant uptake between biosolids
fertilizers and inorganic fertilizers. The Canadian limits for metal additions to the soil are
annualized long term (45 year) average values. The extent to which current data can be
extrapolated to a 45 year trend is not known. Assuming an annual addition of a constant amount
of the same type of fertilizer to the soil may not be realistic. Nonetheless, this report identifies
106
-------
several fertilizer types that exceed the annualized pollutant loading rates allowable in Canada,
and, identifies a few product types that approach the U.S. biosolids limits when applied at
maximum nutrient application rates.
Fertilizer products are compared in this report with respect to the amount of nine heavy
metals the product would add to soil, assuming a single application of the product per year. This
is termed the yearly soil addition rate of a metal (or "yearly addition of metal X", see Index of
Terms). The yearly soil addition rate of a metal is the concentration of that heavy metal in the
product per desired nutrient ingredient multiplied by the nutrient application rate, with all
appropriate conversion factors applied. For those fertilizer products with lower nutrient content, a
proportionally greater amount of the undesirable heavy metal will be added to the land in
achieving a consistent nutrient application rate. Therefore, a fertilizer product may contribute
high levels of heavy metals to soil when the heavy metal concentration in the product is high
and/or when the desired plant nutrient is at a low level in the product.
For this report, the yearly addition of each metal was calculated for each individual
product at three nutrient application rates- an average nutrient application rate, a high rate and at
the maximum application rate recorded for this nutrient. An extended appendix of mis report
(Appendix G) contains the yearly soil addition rate of each metal in each product when applied at
these three nutrient application rates. The aggregate of these individual yearly addition rates,
then, produced the average soil metal addition rate for a fertilizer product category (e.g., P2O5
fertilizers) at the three different nutrient application rates. This aggregate is termed the product
average yearly addition of metal X (see Index of Terms). This summary includes discussions of
the yearly addition of metals hi terms of both the individual product giving the highest yearly soil
addition of a specific metal, and in terms of the product average yearly addition rates for metals.
The calculations performed here showed that the product average yearly addition rates of
metals to soil would not exceed the U.S. biosolids annual pollutant loading rates for any fertilizer
category evaluated. This finding applied to both natural ore-derived fertilizers and industrial by-
product derived fertilizers.
The calculations also showed that the product average yearly addition rates of metals to
soil rarely exceeded the annualized Canadian Fertilizers Act limits for metals additions. The
particular instances when the product average addition rate of metal to soil exceeded the Canadian
limits were found in the following combinations of heavy metal and fertilizer categories, and this
occurred only at the maximum nutrient application rate:
Arsenic in: liming materials (CaCO3 applied at 15,000 Ibs/acre once every 3 years)
iron fertilizers (iron applied at 30 Ibs/acre every year)
The Canadian standards are exceeded more frequently for individual fertilizer products, and are
exceeded for metals other than arsenic. A total of 38 cases were identified where a particular
heavy metal in an identified individual fertilizer product would exceed Canadian fertilizer
standards when applied at the maximum nutrient application rate. These cases include:
Cadmium in: NPK fertilizers applied for P2O5 content [10 products of 91 evaluated
exceeded limits; 10 of 91]
107
-------
Phosphate fertilizers [1 of 61]
Liming materials [3 of 10]
Zinc fertilizers [3 of 22]
Lead in : NPK fertilizers applied for P2O5 content [4 of 91 ]
Liming materials [2 of 10]
Zinc fertilizers [6 of 63]
Iron fertilizers [1 of 3]
Arsenic in: NPK fertilizers applied for P2O5 content [ 1 of 84]
Liming materials [3 of 10]
Iron fertilizers [1 of 3]
Mercury in: Liming materials [1 of 8]
Nickel in: Liming materials [1 of 8]
Zinc in: NPK fertilizers applied for N content [1 of 49]
Of the products listed above, 18 exceeded Canadian standards at the high nutrient
application rate, and 8 exceeded the standards at the average nutrient application rate. Data were
gathered here on 345 fertilizer products; 1389 combinations of fertilizer product and metal at three
application rates (total of 4167 data points) were compared with Canadian standards. (Data on an
additional 537 combinations of unregulated heavy metals in products were also gathered). Since
some products exceeded standards in more than one metal, the number of individual products
exceeding the standards for at least one metal is greater than 2.7% (38 of 1389), but less than 11%
(38 of 345).
Figure 5-10 identifies those fertilizer categories where the product average yearly
addition rate of a metal is likely to double the average level of that metal in background US soils
in 45 or fewer years, when the nutrient is applied at either the average (open box) or maximum
(closed box) application rate. Similarly, this figure also identifies those instances where at least
one individual product within a category exists that may double the average background level in
45 or fewer years, when the nutrient is applied at either the average (open circle) or maximum
(closed circle) application rate. These scenarios assume yearly applications, with exception of
lime, which is applied once every three years. For example, the product average application rate
of cadmium (Cd) from either NPK-P fertilizers (NPK fertilzers applied for P2O5 content) or from
P2O5 fertilizers will double the average background Cd soil level in 45 or fewer years when either
the average or maximum nutrient (P2O5) application rate is used every year. In addition, there
were individual NPK-N, NPK-P and P2O5 products identified that would double background soil
Cd levels in 45 or fewer years if applied each year. There were no potash (K2O), gypsum,
manganese (Mn), or boron (B) fertilizer products identified that would double the indicated soil
metals levels in 45 or fewer years. In contrast, liming materials were identified that might double
the soil levels of all nine metals with consistent use (application once every three years) within a
45 year time frame.

APPENDIX A
FERTILIZER CONSUMPTION IN THE U.S.
A-1
-------
Appendix A. Fertilizer Consumption in the U.S.
The tables in Appendix A have been abstracted from electronic files created by the
Association of American Plant Food Control Officials (AAPFCO). The data in these tables are
for the year ending June 30,1996. Slight differences in reported values between the tables in this
report and Commercial Fertilizers 1996 (AAPFCO and TFI) are due to the inclusion of liming
materials and some minor differences in the definition of multiple nutrient fertilizers and "other"
fertilizer groupings. Tables A-l through A-5 contain the tons of different types of fertilizers and
micronutrients consumed for each state and Puerto Rico. The tables are organized with the states
grouped into geographic regions of the country. These tables are:
A-l. East North Central (IN, IL, MI, OH, WI) and
East South Central (KY, AL, MS, TN)
A-2. West North Central (KS, IA, MN, MO, NB, ND, SD) and
West South Central (LA, AR, OK, TX)
A-3. New England (CN, ME, MA, NH, NY, RI, VT) and
Middle Atlantic (DE, MD, NJ, PA, WV)
A-4. South Atlantic (FL, GA, NC, SC, VA)
A-5. Mountain (AZ, CO, ID, MT, NM, NV, UT, WY),
Pacific (AK, CA, HI, OR, WA) and Puerto Rico
The total U.S. fertilizer consumption, by fertilizer type is presented in Table 2-1.

APPENDIX B
CROP-SPECIFIC FERTILIZER USE IN THE UNITED STATES
B-1
-------
Appendix B. Crop-Specific Fertilizer Use in the United States
The USDA ERS-NASS data presented in this appendix come from the most recent
surveys of field, fruit and vegetable crops. These surveys, the sampling methodology, coverage
and data collection are described in Agricultural Resources and Environmental Indicators (AREI)
Production Management Appendix (1997).
Fruit and vegetable data were abstracted from the Chemical Use Surveys that were
initially funded under the 1989 President's Food Safety Initiative. These surveys are conducted
by NASS "using personal enumeration of a stratified systematic sample of growers who produce
at least one acre of the targeted crops." The information collected on fertilizer use, acreage
planted, and application rates are survey data for the major crop producing states and do not
represent the totality of farms in the U.S. raising these crops. Surveys are conducted odd years
for fruit (latest available survey performed in 1995, representing the crop year 1995, and reported
in 1996) and even years for vegetable crops (latest available survey is for the crop year. 1994
reported in 1995).
The latest field crop usage data, covering 70 to 90% of the total U.S. crop, are from the
Agricultural Resources Management Survey (ARMS) of 1996 which combines the former
Cropping Practices Surveys with the Farm Costs and Returns Survey. This survey has three
phases. Phase n, conducted in the autumn, for the proceeding crop year, collects data on
agricultural production practices, resource and input use, and production. In this survey, "a
multi-frame, stratified sampling procedure is used. Results are weighted and aggregated to
develop state, regional and national estimates." Note that there are some crops (strawberries,
cantaloupe, honeydew melon and watermelon) in the vegetable survey that are commonly
considered fruits.
Detailed descriptions of the survey procedures are presented in the following documents
available on the internet from http://mann77.mannlib.cornell.edu.:

APPENDIX C
FERTILIZER CONSUMPTION BY USE
C-1
-------
Appendix C. Fertilizer Consumption by Use
The AAPFCO data set, described in Appendix A, contains a variable for farm versus non-
farm use. The tables in this Appendix present fertilizer consumption by state and region for farm
and non-farm use. Non-farm use includes application to residential and recreational properties.
Note that there are five states for which the variable "use" was left blank. These states
(Arkansas, Iowa, Kentucky, Ohio and Texas) have been excluded from the following tables. The
use codes are 1 = farm and 2 = non-farm. For several states the non-farm code (2) was not used.
NA is inserted in the Appendix tables for non-farm use for these states although it is unclear
whether there was no non-farm use or the the two uses could not be separated out based on data
collected by the individual states.
The following tables are included in this appendix:
Table C-l. Fertilizer Consumption by Use, East North Central States, 1996 (tons)
These states are: IN, IL, MI, WI
Table C-2. Fertilizer Consumption by Use, East South Central States, 1996 (tons)
These states are: AL, MS, TN
Table C-3. Fertilizer Consumption by Use, West North Central States, 1996 (tons)
These states are: KS, MN, MO, MB, ND, SD
Table C-4. Fertilizer Consumption by Use, West South Central States, 1996 (tons)
These states are: LA, OK
Table C-5. Fertilizer Consumption by Use, New England States, 1996 (tons)
These states are: CT, ME, MA, NH, RI, VT
Table C-6. Fertilizer Consumption by Use, Middle Atlantic States, 1996 (tons)
These states are: DE, MD, NJ, NY, PA, WV
Table C-l. Fertilizer Consumption by Use, South Atlantic States, 1996 (tons)
Thee states are: FL, GA, NC, SC, VA
Table C-8. Fertilizer Consumption by Use, Mountain States, 1996 (tons)

compensations as established by regulation, or (2) if the overall index value
of the fertilizer is below the level established by regulation, a penalty
payment of times the value of such deficiency or deficiencies shall
be assessed. When a fertilizer is subject to a penalty payment under both
(1) and (2), the larger penalty payment shall apply. (Official 1994)
(b) Penalty payment for other deficiencies - Deficiencies beyond the
investigational allowances as established by regulation in any other
constituent(s) covered under Section 3 paragraph (c](1) 8 and C of this Act,

same in the appropriate state fund allocated to fertilizer control service. If
upon satisfactory evidence a person is shown to have altered the content of
a fertilizer shipped to him by a registrant/licensee, or to have mixed or
commingled fertilizer from two or more suppliers such that the result of
either alteration changes the analysis of the fertilizer as originally guaranteed,
then that person shall become responsible for obtaining a registration/license
and shall be held liable for all penalty payments and be subject to other
provisions of this Act, including seizure, condemnation and stop sale.
(d) A deficiency in an official sample of mixed fertilizer resulting from non-
uniformity is not distinguishable from a deficiency due to actual plant
nutrient shortage and is properly subject to official action. (Official 1985)
(e) Nothing contained in this section shall- prevent any person from appealing to
a court of competent jurisdiction praying for judgment as to the justification
of such penalty payments.
