                              PREFACE

     The disposition of increasing quantities of municipal wastewater
treatment sludges and animal waste is a subject receiving considerable
attention by various Federal, State, and local representatives.

     The Office of Solid Waste Management Programs is currently  evalu-
ating the reuse potential of municipal wastewater treatment sludges
and animal waste as a soil conditioner and/or as a fertilizer supplement.
The decision to dispose of these waste materials in a disposal site or
by some other means should only be reached after all utilization
opportunities have been thoroughly investigated and dismissed.

     This report provides information on land availability, crop pro-
duction, and fertilizer requirements in the United States as it  relates
to animal waste and sewage sludge utilization and disposal.  Information
on health effects, plant toxicity, metals content, and the relative
economics of utilizing sewage sludge and animal waste on agricultural
lands including collection, transportation, and application costs are
not considered within the scope of this report.  The Office of Solid
Waste Management Programs, however, does intend to address these very
important issues as part of its total effort on utilization of animal
waste and sewage sludge.

                     INTRODUCTION AND SUMMARY

     The question of what to do with the increasing amount of animal
waste and sewage sludge generated in the United States annually is an
extremely perplexing environmental problem of recent and great concern.
The disposition of these solid waste residues has been commonly
associated with problems of air and water pollution, odors, and other
nuisance conditions considered to be of an adverse nature.  The problems
that arise are generally the result of mismanagement involving improper
distribution and concentration of these waste products rather than an
inability on the part of nature to fully assimilate the vast quantities
of waste generated.

     Until the mid-1940's, the disposition of animal waste presented
few problems as the majority of the waste generated was recycled
through its application to prime agricultural lands.  It was used
extensively for its fertilizer value and as a source of organic matter
to improve the physical characteristics of cultivated soils.  It was
regarded by many as the mainstay of most soil fertility and improvement
programs and as such was considered more of an asset to the average
farmer than an economical liability, as it is commonly looked upon today.

     Shortly after the conclusion of World War II, the agricultural
industry experienced a tremendous increase in the production, utiliza-
tion, and availability of low cost commercially produced nitrogen-
containing fertilizers.  This trend, spurred by greater demands for
higher profits and productivity, resulted in animal waste being
relegated to a much lesser role in the agricultural community.  Recent
shortages and higher fertilizer cost have had a significant impact that
has not been fully assessed with regard to utilization of animal waste
on land.  However, it appears the majority of the animal waste is once
again being applied to the land as a supplemental source of primary
nutrients to help offset the increasing demand for higher cost commer-
cially produced fertilizers.

     Sewage sludge, on the other hand, has always been and in all prob-
ability will continue to be somewhat of a problem because of its
inherent adverse qualities when not handled properly.  Historically,
the majority of the nation's population throughout the early 1900's
resided on farms and was serviced by individual pit privies or septic
tanks and tile fields.  This resulted in relatively small and widely
dispersed accumulations of sewage sludge that presented very few
problems.  Since that time there has been a significant increase in
the U.S. population along with a general trend toward migration of the
nation's population into the more urban and metropolitan areas.  This,
in addition to a relatively rapid growth in the construction of more
and increasingly efficient wastewater treatment facilities, increased
industrial waste loadings, and enactment of more stringent air and
water pollution control legislation, has resulted in tremendous

-------
increases in the volume of wastewater treatment sludges generated as
well as significant changes in its physical and chemical characteristics.

     This report focuses on the nutrient value and soil improvement
characteristics of animal waste and sewage sludge.  Although purposely
omitted, it is acknowledged that additional information must be obtained
and thoroughly investigated relative to plant toxicity, metals accumu-
lation, nitrate pollution, public attitudes, and the economics of
transportation and application before formulation of any final con-
clusions or recommendations on how to best utilize animal waste and
sewage sludge on land can be developed.  Several of the above areas are
currently under investigation by EPA's Office of Research and Develop-
ment, Office of Water Programs, the U.S. Department of Agriculture,
the Food and Drug Administration, and various private, State, Regional,
and local government Agencies.  It is not expected that any conclusive
results will be available concerning the long-term effects of sludge
application to soils within the next 3 to 5 years.  Until such time
that conclusive data are available, it is highly recommended that sludge
be applied only in accordance with acceptable sludge management practices
and that its application to cultivated soils be highly controlled or
regulated and monitored to minimize any adverse environmental effects.

                           ANIMAL WASTE

     The general nature of the animal production industry in the United
States has changed dramatically over the past several decades.   What
was once considered a small, family-operated, diversified industry has
evolved into a much larger, highly specialized, cost-effective  business
enterprise.  The total number of animals on feed or held in confinement
has nearly doubled since the mid-1940's.l  Directly associated  with
these changes has been a tremendous increase in the amount of animal
waste generated in confined and/or concentrated areas.  It is currently
estimated that 2 billion tons (wet weight) of animal waste is generated
annually in the United States.2  Table 1 presents data relative to the
number of animals and their respective contributions to the total solid
waste stream.

     Nearly 80 percent of the animal waste generated falls on open
pasture or grazing land and for all intents and purposes presents little
or no problems due to its dispersed nature and remote location.  The
United States Department of Agriculture estimates at least one-half to
two-thirds of the remaining animal waste generated in confined  or con-
centrated areas is currently being recycled through its application to
available croplands.3  Although a detailed survey of recent practices
has not been conducted that accurately reflects the real impact of
today's tight energy supplies and high cost of commercial fertilizers,
it has been reported that utilization is greatly increasing.^

     The nutrient content and quantity of animal waste generated are
highly dependent upon such factors as the type of animal, its age, size,
sex, and breed, the type and amount of feed ration, the methods of
storing, handling, and processing the waste, as well as a wide  range
of other environmental and physical considerations (e.g., soil  types,
climate, annual precipitation, animal density, etc.).

     Typically 50 to 60 percent of the nitrogen, and 90 percent of the
phosphorous and potassium contained in fresh animal waste is recoverable
for possible reuse.  The nutrient losses that normally occur are a
result of long-term storage and handling of the material before it is
ultimately applied to the land.  It has been reported that 60 to 80
percent of the nitrogen losses that do occur are a direct result of
leaching and volatilization while the remaining losses are primarily
associated with surface water runoff.-*  A complete accounting of all
nitrogen entering or leaving a particular feedlot is extremely  difficult
to predict because of the wide range of variables that can and  do affect
nitrogen availability.  In addition to the nitrogen losses, it  is
estimated that only 30 to 50 percent of the nutrient value applied in
the form of total nitrogen is available for crop utilization during the
first year after application with progressively decreasing amounts of
nitrogen becoming available in each successive year.6

     Table 2 lists the average percent of elemental nitrogen,  phosphorous,
and potassium commonly found in the various types of animal waste.   As
indicated in Table 3 the maximum amount of nitrogen estimated  to be
recoverable for reuse from the animal waste generated in confined and
concentrated areas is equal to approximately 1.5 million tons  per year.
Assuming one-half to two-thirds of the confined animal waste is  already
being returned to the land, only 500,000 to 750,000 tons of nitrogen
could be considered as available for potential reuse on land.  The
effective nitrogen value of the confined animal waste as applied would
only be equivalent to 100,000 to 300,000 tons of available nitrogen.
This represents 1 to 4 percent of the total nitrogen consumed  in the
United States annually.  If applied at an application rate such  that
100 pounds of available nitrogen were applied per acre, animal waste
could satisfy the nitrogen demand of 2 to 6 million acres of corn.
Depending upon the plant requirements and soil fertility, the  application
rates may have to be adjusted.  For example, the same amount of  animal
waste applied at a 50 pound per acre application rate of available
nitrogen could satisfy the nitrogen demand of 4 to 12 million  acres of
wheat.

                           SEWAGE SLUDGE

     Currently there are on the order of 20,000 to 25,000 municipal
sewage treatment plants in operation throughout the United States.
These facilities service nearly 155 million people.1  The remaining
population is served by private collection and disposal systems
ranging from individual pit privies to the more elaborate types of
small, packaged sewage treatment plants.

     The type of sewage treatment plant, its capacity, solids removal
efficiency, and method of sludge handling and disposal varies consid-
erably as does the character of the sewage being treated from one
location to another.  It is estimated there are in excess of 40,000
possible configurations or combinations of systems that can be derived
utilizing current wastewater treatment practices and technology.8  it
is partly due to this extreme variability that it is very difficult
to generalize about the character and quantity of sludge emanating
from a "typical" sewage treatment plant.  Table 4 lists, according  to
general classification, the number and type of sewage treatment plants
in the United States and the estimated population served by each.

     The quantity of sewage solids generated varies considerably with
the type of sewage treatment process.  Many secondary and tertiary
treatment processes necessitate the addition of chemicals, thus greatly
increasing the solids content and amount of sludge removed.  This
variation ranges from approximately 0.04 to 0.35 pounds of dry solids
per capita per day.9  Industrial waste loadings may increase the
average sludge generation rate of a particular treatment plant 20 to 50
percent depending upon the type of industry and its percent contribution
to the total daily flow of solids into the municipal treatment facilities.
In many municipalities, the amount of industrial waste exceeds that of
the municipal waste.  Due to the extreme variation from one industrial
waste to another, it was considered far beyond the scope of this report
for industrial wastes to be included in the sludge generation figures
and they were therefore omitted.  Table 5 categorizes the various
municipal treatment processes into one of three major classifications:
(1) no treatment, (2) Category I (minor and primary treatment systems,
and (3) Category II (intermediate, secondary, and tertiary treatment
systems).

     The total amount of raw undigested domestic sewage sludge currently
generated in the United States from Category I and II type systems  is
calculated to be approximately 5.6 million dry tons per year.  This
material consists essentially of the settleable and dissolved solids
removed from the raw sewage and any chemicals that were added as part
of the treatment process.  Raw sewage sludge having undergone practically
no decomposition is highly unstable, putrescible, disagreeable in phy-
sical appearance, characteristically has a foul odor, and contains
thousands of disease-carrying agents.  It is for this reason that

digestion or some further means of treatment or stabilization is
generally required before the sludge is considered acceptable for
utilization.

     The two major objectives of sewage sludge digestion are to reduce
the total volume of solids to be handled and to biologically stabilize
the sewage solids for safe handling.  High rate digestion of sewage
sludge typically results in a 40 to 60 percent reduction in volatile
solids, which generally yields a 30 to 40 percent reduction in total
solids.10

     Sewage sludge normally contains many of the elements that are
known to be essential to all plant life such as nitrogen, phosphorous,
potassium, calcium, magnesium, and a multitude of other minor and trace
elements (Table 6).

     Although essential to plant life, these elements are often found
in concentrations known to be detrimental to plant life.  In certain
cases where the metals content of a particular sludge is known to be
excessive, it may be necessary to establish pretreatment standards and
require users to conform with the standard before discharging into the
municipal sewer system.  If a particular problem cannot be attributable
to a specific user, some other way of removing or decreasing the  con-
centration level of the element or elements in question must first be
attained before further consideration is given to sludge application to
crop or pastureland.

     The nitrogen content of sewage sludge is relatively low when com-
pared to that of most commercial grades of fertilizer.   As displayed in
Table 7, the nitrogen content of sewage sludge will vary from 1 to 6
percent.  The actual nitrogen content of a particular sludge is highly
dependent upon the unit processes involved in the treatment and char-
acter of the sewage coming into the plant.  It has been reported  that
as much as 30 to 50 percent of the nitrogen contained in the raw  sewage
sludge is in the readily available ammonia or nitrate form.Hป1^   The
remaining nitrogen is in a lesser available organic form and is slowly
released over a much longer period of time.  Table 7 presents compar-
ative figures on the nutrient content of several typical digested and
undigested sludges.  As indicated in the table, anerobic digestion
greatly reduces the nitrogen content of sewage sludge by a factor of
30 to 40 percent on a dry solids basis.  This is due primarily to
solubilization of the nitrogen during the digestion process and its
ultimate removal through dewatering of the sludge after digestion.
From a nitrogen standpoint, heat-dried activated sludge is by far a
superior product.  This is because of the more advanced nitrification
state of the activated sludge and the fact that very little nitrogen
loss occurs through solubilization since the sludge is  heat-dried
rather than digested and dewatered.

     It is estimated that approximately 100,000 tons of nitrogen are
contained in the sewage sludge generated annually in the United States
(Table 8).  Approximately 20 to 50 percent of this nitrogen is readily
available for crop production within the first year after application
with smaller amounts becoming available in each successive year.  A
recent EPA survey reports that 25 percent of the sewage treatment
plants in the United States are currently disposing of their sewage
sludge by land-spreading.13  The most common type of land application
reported was utilization on cropland and pasturelands.  Other types of
land application included public parks, golf courses, airports,
abandoned strip mines, cemeteries, plant grounds, highway median strips,
woodlands, and sanitary landfills.  Based upon its available nitrogen
content, sewage sludge could satisfy 1 to 5 percent of the total non-
agricultural demand for nitrogen-containing fertilizer materials.
Currently it is estimated that 15 percent of the total annual national
consumption of nitrogen is for non-agricultural purposes.14

                      FERTILIZER REQUIREMENTS

     Fertilizer consumption in the United States totaled 42.5 million
tons in 1973.15  xhe primary nutrient content (i.e.,  nitrogen, phos-
phorous, and potassium) exceeded 17.8 million tons,  reflecting a 3.5
percent increase over that of the previous year.15 p.8  Nitrogen and
phosphorous consumption in 1973 were both up 4 percent,  while potassium
(potash) was up only 2 percent over the 1972 figures.15   In general, the
use of fertilizer has been increasing at a rate of 4  percent per year
over the last 20 years as shown in Figure 1.15 p.5  Projections for the
year 1974 indicate nitrogen consumption will reach 9.3 million tons or
about 12 percent above that consumed in 1973.1^ P-3  This is due pri-
marily to an increase in the total acreage of major crops planted in the
early spring of 1974 along with a slight increase in  the amount of
nitrogen applied per acre (Table 9).

     It has been reported that 18.5 million tons of nitrogen are re-
quired each year to sustain current levels of crop production and soil
fertility in the United States.I2 P-67  Approximately 60 percent of this
nitrogen demand is supplied by natural processes,  while  the remaining
40 percent is derived from commercially produced nitrogen-containing
fertilizers.  Rain and snow contribute 1.0 to 1.5 million tons of
nitrogen to U.S. cropland each year, while nitrogen-fixing plants and
soil bacteria supply the remainder of the naturally available
nitrogen.I2 P-68

     The pathway nitrogen follows in nature, whether  the nitrogen source
is organic or inorganic, natural or commercially produced, is extremely
difficult to predict.  The processes that affect the  form in which
nitrogen is found in soils (i.e., mineralization,  nitrification, denitri-
fication, immobilization, fixation, absorption, volatilization, cation
exchange, convection, dispersion, and plant uptake)  take place concur-
rently and at different rates largely dependent upon  the cropping
practices, type of crop planted, soil characteristics, and climatic
conditions (Figure 2).  Several attempts have been made  to establish a
national nitrogen balance with little success.  Gross estimates, however,
indicate that approximately 3 million tons of nitrogen are depleted from
the nation's soil each year.12 P-70

     The commercial production of inorganic nitrogen  has increased at
an average rate of 7.8 percent per year over the past 10 years, and is
expected to continue to increase at a rate of 6 percent  through 1980.15 P-4
Before World War II, most nitrogen was derived from the  importation of
Chilean ammonium nitrate, by-product recovery of ammonium sulphate from
the coking of coal, natural organic nitrogen-containing  materials, and,
to a very limited extent, synthetically produced nitrogen.  Table 10
lists some of the more common natural nitrogen-containing organic
materials once used.  Today these materials account for  less than 1 percent
of the total fertilizer market.1?  The main reason given by the fertilizer
industry for the decreased utilization of natural organic nitrogen

fertilizers is the high cost per applied unit of nitrogen.  In addition,
commercially produced inorganic fertilizers can be produced more cheaply
and in greater quantities, and can be formulated to provide a more
regulated release of nitrogen than can natural organic nitrogen-
containing fertilizers.

     Overall, the commercial fertilizer industry consists of about 100
large primary producers of the basic NPK (nitrogen, phosphorous, and
potassium) constituents.16 p.6  ^ detailed listing of the primary
producers and respective number of plants is summarized in Table 11.
Many primary producers manufacture more than one type of fertilizer and
therefore the number of firms and plants are not additive.

     The average capital cost of constructing a 1,000 ton per day
anhydrous ammonia plant ranges from $40 to $60 million and takes several
years to construct.18  xhe high capital investment and amount of lead
time required to construct these facilities is one of the main reasons
given by the fertilizer industry today for the lack of sufficient
production capacity and inadequate supplies of nitrogen fertilizers.

     In addition to the primary nutrient producers, there are thousands
of smaller blending or mixing plants.  These plants mechanically mix
and formulate bulk quantities of the basic fertilizer ingredients
according to predetermined specifications.  Many of the large primary
producers distribute their products directly through their own farm
stores, while the majority sell their products to retailers or farm
cooperatives.  Bulk blended fertilizers are generally applied to the
fields the same day they are mixed.

     Approximately 50 percent of the commercially produced fertilizer
materials consumed in the United States are applied to the soil as a
mixture.l^ p.10  Anhydrous ammonia (the basic nitrogen source for over
95 percent of the nitrogen-containing fertilizers) accounts for nearly
40 percent of the nitrogen that is separately applied to the soil.  In
1973 over 3 million tons of anhydrous ammonia were applied to the soil
by direct application.

     Anhydrous ammonia is produced by the ammonium fixation process
utilizing air and natural gas as its basic raw materials in the presence
of a catalyst at elevated temperatures and pressure (i.e., 700ฐC at
40 PSI).  Air contains approximately 80 percent nitrogen by volume and
therefore constitutes virtually an unlimited supply of nitrogen.  Natural
gas serves as a source of energy and hydrogen necessary to complete the
reaction.  The production of anhydrous ammonia requires approximately
40,000 cubic feet of natural gas per ton of nitrogen produced.  Anhydrous
ammonia is 82 percent nitrogen.  It is estimated that 600 billion cubic
feet of natural gas were consumed in the production of anhydrous ammonia
in 1973.  Approximately 75 percent of the anhydrous ammonia produced
was consumed by the agricultural industry.  This represents 450 billion
cubic feet of natural gas or about 1.9 percent of the total natural gas
consumed in the United States during the year 1973.

     The availability of an adequate supply of natural gas is therefore
essential to the production of anhydrous ammonia in today's market.   The
fertilizer industry, however, is not limited to the use of natural gas
in the manufacture of anhydrous ammonia.  There are several alternate
methods of production currently available.  In Europe, for instance,
fuel oil, coal, and naphtha are widely used.  These methods, however,
are far more expensive than natural gas.

     As the cost of natural gas continues to climb upward and its
availability becomes more limited, it is highly probable that localized
shortages of anhydrous ammonia will occur.  Few industry observers see
the supply of natural gas being equal to the demand now or in the near
future and therefore project that the United States will have to look
more toward foreign imports of nitrogen to meet its fertilizer needs.
Currently the United States is a net exporter of nitrogen by a ratio  of
nearly 1.5 to 1.16 p.6  xhe United States exported 1.4 million tons of
nitrogen in 1973 while importing only 0.9 million tons (Figure 3).

     The 10 leading states in order of anhydrous ammonia production are
listed in Table 12.  Over 75 percent of the anhydrous ammonia produced
in the United States is currently manufactured in the 10 states listed.

     The United States produces over 25 percent of the total anhydrous
ammonia consumed in the world. " P-49  Approximately 75 percent of the
anhydrous ammonia produced in the United States is earmarked for agri-
cultural purposes while the remainder is used in manufacturing plastics,
explosives, food processing, additives, and for other miscellaneous non-
agricultural purposes (Figure 4).

     Tables 13 and 14 list by state in order of consumption, the total
amount of fertilizer and primary nutrients consumed in 1973.  Most of
the major fertilizer and primary nutrient-consuming states (with the
exception of Florida and California) fall within the areas referred to
as the Corn, Cotton, and Wheat Belts.  Corn, cotton, wheat, and soybeans
account for over 50 percent of the total fertilizer consumed in 1973.
Table 15 summarizes the respective amounts of primary nutrients applied
to the four major crops produced in the U.S. in 1973.  Table 16 reflects
the total acreage fertilized and the average amount of fertilizer
applied per acre over the past three years.

     The U.S. produces nearly 40 percent of the total world supply of
phosphorous rock.16 p.54  Approximately 85 percent of the U.S. demand
for phosphorous is used for agricultural purposes, while the remainder
is used in the manufacture of detergents, food products, and explo-
sives. 16 p.53  Over 80 percent of the phosphate rock mined in the U.S.
(the basic source of phosphorous in the production of phosphatic ferti-
lizers) is extracted from strip mines in the states of Florida, Tennessee,
and North Carolina.16 p.51  j^ takes approximately 3 tons of phosphate
rock to produce 1 ton of phosphorous (ฅ205)'^  The known reserves in
the states of Florida and Tennessee represent nearly 40 percent of the
                                  23

nation's total available supply of phosphate rock, a quantity estimated
to be sufficient to last 30 to 40 years.16 P-51  The mining of phosphate
rock, like anhydrous ammonia production, is an energy-intensive enter-
prise.  It has been reported that 10 percent of the total electrical
power sold in the State of Florida is consumed by the phosphate rock
mining industry.^ p.5  xhe majority of the phosphate rock mined in the
State of Florida is strip mined with the use of large electric cranes
requiring vast amounts of electrical power.  It requires approximately
100 KWH of electrical power, 6 gallons of fuel oil, and 3,000 gallons
of water to extract and process a sufficient volume of raw materials
to produce 1 ton of available phosphate rock.   P*"  Additional power
and natural resources are required to process the phosphate rock into
a usable fertilizer product (e.g., phosphoric acid, ammonium phosphate,
and elemental phosphorous).  Therefore, it is projected that major
cutbacks in the availability of adequate supplies of energy would have
a significant impact on the phosphate rock producing industry.  In
addition to its basic power needs, more than 50 percent of the nation's
sulphur is also consumed in the manufacture of phosphatic fertil-
izers. I? p.366  Shortages of phosphatic fertilizers are expected through
1975 due to insufficient production capability within the industry.
However, by the end of 1976, additional production capacity equal to
2 million tons of ?2ฎ5 ^s expected to come on line, thus alleviating
somewhat the pressures upon the industry.

     Approximately 95 percent of the potassium mined in the United
States is consumed in the manufacture of fertilizer.16 p.61  Nearly
100 percent of all potassium is obtained from underground sources
through solution mining or by drilling and blasting.  The U.S. imports
nearly half of its potassium from Canada, while the remainder is ex-
tracted from domestic mines located in Carlsbad, New Mexico and
southeastern Utah.  The total U.S. reserves are expected to last 20
years.  No shortage of potassium fertilizer is expected in the immediate
future.

     The cost of fertilizer has risen sharply since the lifting of
Phase IV price controls on fertilizer products on October 25, 1973.  The
U.S. Department of Agriculture reports the average cost of a ton of
fertilizer to have increased from about $75.00 per ton in mid-1973 to
well over $140 per ton in the fall of 1974.14 p.4  The price of anhydrous
ammonia alone has nearly tripled over the same time span (Appendix G).
If the cost of fertilizers continues to rise at the current rate, the
total national expenditure to farmers for commercially produced fertilizer
materials in 1975 could well exceed $6.5 billion—a dramatic increase of
more than 120 percent above that spent in 1973.  The average cost of
fertilizer to the farmer per pound of equivalent N, P, and K delivered
as of September 1974 was approximately 25, 40, and 5 cents per pound,
respectively.20

     In addition to the three primary nutrients already mentioned, there
are several important secondary and micro plant nutrients that have been
                                  31

-------
identified as essential to plant life.  Several of the more important
of these are listed in Table 17.  The quantity of secondary and micro
plant nutrients required for maximum plant development is not thoroughly
understood at this time.  It is known that the amount required varies
with the type of plant, soil characteristics,  climatic conditions,  and
the season of the year.  Table 18 displays the average amount of primary,
secondary, and micro plant nutrients required  to produce a specified
type and quantity of crop.  The range between  beneficial and detrimental
effects to a plant with regard to many micronutrients is so very small
that it is extremely difficult to determine.   In various research efforts
where such determinations have been attempted, it was found that the
availability of a specific micronutrient was more important than the
total quantity of the micronutrient present.   This is also very important
with regard to primary nutrients.  Field experiments have shown plant
uptake of nitrogen to range between 25 and 85  percent, depending upon
specific site conditions and the type of crop  harvested.

     Table 19 lists the various compositions of materials commonly used
in the production of commercial fertilizers.   As few as one or as many
as 10 may be used in the production of a specific grade of fertilizer.
Often, a filler material such as sand, or more commonly limestone,  is
used to produce the desired concentration of nutrients in a mixed
fertilizer.

                         LAND AVAILABILITY

     Since land is our Nation's most valuable resource,  it  is  appropriate
to consider how much land there is available and how it  is  currently
being used.

     As demonstrated in Figure 5,  the overall distribution  of  the Nation's
land among the major land use categories has not changed significantly
over the past several decades.  The total land area of  the  United States
consists of approximately 2 1/4 billion acres.1 p.507  The  48  contiguous
states alone account for nearly 85 percent of this  total land  area.   Less
than 20 percent of the Nation's land is currently under  cultivation.   It
has been estimated that only 60 percent of the land that is considered
suitable for regular or intermittent cultivation is actually being used
for that purpose.21  Almost 40 percent of the Nation's  land is used for
livestock grazing and an additional 30 percent is in forestland,  wild-
life refuges, and recreation areas.  The remaining  land  falls  into a
miscellaneous category consisting  of desert lands,  mountainous regions,
tundra, urban areas, and public lands (Table 20).

Cropland

     The total land area available for cultivation-in 1969  was approx-
imately 472 million acres.21 p-2  This figure includes  all  cropland
harvested, not harvested due to crop failure, land  used  only for  pasture,
and land in summer fallow or otherwise lying idle and not being used
(Figure 6).

     Approximately 2 1/2 million acres of prime cropland are removed  from
production each year as a direct result of urban sprawl, highway  and
airport construction, strip mining operations, and a multitude of various
other reasons.  The net loss of available cropland, however, is partially
offset by the addition of an estimated 1 1/4 million acres  of  reclaimed
land each year of which approximately 60 percent consists of newly
developed irrigated land.  Although thousands of acres  of cropland are
permanently lost each year, agricultural experts do not  foresee any
great danger of the United States  running out of available  cropland to
meet its ever increasing demand for food and fibre production.

     If one considers the total amount of cropland  or other lands that
are potentially available for land application of sewage sludge and
animal waste, it soon becomes apparent that more than enough available
land exists to utilize safely all  of the waste produced. It is estimated
the total land area required for utilization of all the available sewage
sludge and animal waste generated  in the United States—assuming  the  soil
has the capacity for assimilating  up to 10 tons of dry  solids  per acre
per year—is approximately equal to 1.3 percent of the  total land area
in crop production.  As indicated previously, at least  one-half of the
confined animal waste and possibly as much as 25 percent of the sewage
sludge generated is already being returned to the land.   Depending upon
                                  36

the actual utilization rate or capacity of the soil to assimilate the
animal waste and sewage sludge applied, this annual land requirement
could be reduced significantly.

     Agronomists have long recognized the potential benefits of applying
animal waste and sewage sludge to cropland.   Sewage sludge and animal
waste, although very similar, do differ from one another in several
respects.  Sewage sludge generally has a much lower organic content,
contains much higher concentrations of metals, and can harbor pathogenic
organisms if not digested properly.  The latter two are primarily
responsible for the adverse reactions often generated in the general
public when considering the use of sewage sludge on food-chain crops.
Similar problems are not commonly encountered when attempting to apply
animal waste to food-chain crops and, therefore, utilization of animal
waste has greatly exceeded that of sewage sludge.

     The U.S. Department of Agriculture maintains  statistics on 79
different types of crops planted in the United States.  Table 21 lists
the total acreage planted in 1973 of each of the 20 principal crops.
Corn, cotton, hay, soybeans, and wheat represent nearly 75 percent of
the total acreage planted and are considered the major crops produced
in the U.S.

     Most animal waste is applied to feed grain crops grown in close
proximity to the major animal-producing areas.  Figure 7 displays the
major land resource regions and crop production areas of the major crops
produced in the United States.  The feed grain, cotton, and wheat-
producing regions are situated in the more rural areas, while dairy,
truck, and specialty crops are typically located in the more populated
areas of the United States.

Urban Areas

     At the time of the 1970 census, 70 percent of the total United
States population resided within the boundaries of the Nation's 242
Standard Metropolitan Statistical Areas (SMSA).21 p.14  An SMSA is
defined by the U.S. Census Bureau as a county of group of counties
which contain at least one central city or twin cities with a combined
population of 50,000 or more people (Figure 8).  It is estimated that
80 percent of the sewage sludge generated in the United States emanates
from within the confines of the Nation's SMSA's.  The concentration of
sludge varies directly with the population density.  As indicated in
Figure 9, the population density of the SMSA urban core averages 3,137
persons per square mile, while the population density of the more rural
sections inside and outside of the SMSA's average 42 and 24 persons per
square mile respectively.21 p.17  The total land area within the Nation's
242 SMSA's in 1970 was approximately 255 million acres.

     Approximately 25 percent of the land area surrounding the major
urban areas within a 22.8 mile radius is classified as cropland and an
                                  40

additional 20 percent is in pastureland.21 p.17  A large portion of this
land is in dairy farms, horticultural specialty crops,  and general farm-
ing, which together account for 17 percent of the national corn crop,
60 percent of the vegetables produced, and 43 percent of the fruit and
nut crop.21 p.16  Horticultural specialty crops such as sod, greenhouse
vegetables, nursery products, bulbs, seeds, flowers, and mushrooms
collectively account for more than 285,000 acres of the available crop-
land surrounding SMSA's (Table 22).  Sod production and nursery products
alone account for nearly two-thirds of the land in horticultural specialty
crops.  Although seemingly very small when compared to  that of the total
national acreage in corn, wheat, cotton, and soybeans,  the total acreage
in sod and nursery products represents a significant amount of land under
cultivation surrounding the large metropolitan areas.

     Sod and nursery product production is very closely related to the
nation's housing industry and is extremely sensitive to the number of  new
housing starts and the overall economy of a particular  region.  The sod
and nursery product industry as well as the nation's sewage sludge is
primarily centered in and around the Northeastern, Great Lakes, and
Southern Pacific States.

     The application of sewage sludge to sod or nursery products appears
to be an excellent means of recycling the nutrient content and soil
improvement characteristics inherent in sludge.  Both sod and nursery
products are non-food chain crops and are located in close proximity
to the sources of sludge generation.  In addition to its soil improvement
characteristics and nutrient content, sewage is an excellent source of
organic matter that could replace the soil removed when a sod crop is
harvested or when trees and shrubs are transplanted.

Strip Mined Land

     In assessing the potential for utilizing sewage sludge or animal
waste, one should not overlook the vast amounts of land that have been
stripped as a result of surface mining operations.  The soil-building
characteristics of sewage sludge and animal waste appear to be excellent
for reclaiming these wastelands.  It is estimated by the U.S. Bureau of
Mines that in excess of 3 million acres of land in the United States
have been disturbed by surface mining.22  xhe states of Pennsylvania,
Ohio, and West Virginia account for over 25 percent of  this total acreage
(Table 23).22 p.110  Only one-third of the total acreage disturbed by
surface mining operations to date in the United States  has been reclaimed,
leaving approximately 2 million acres yet to be improved.22 p.85

     Coal mining accounts for over 40 percent of the total stripped areas,
while sand and gravel mining operations account for an additional 25
percent of the total disturbed acreage (Figure 10).  Experts calculate
that over 100,000 acres of land each year are disturbed by the coal
mining industry alone and projections are this number will continue to
increase paralleling the nation's greater needs for and dependence upon
coal to meet its basic energy requirements.21 p.13

     For the most part, the Nation's coal reserves have remained  untapped.
Less than 5 percent of the total land reserves of this valuable resource
lying within 100 feet of the earth's surface have been mined.21 p.13
Approximately half of the coal consumed in the United States has  been
obtained through surface mining operations.   The states of Montana,
Illinois, North Dakota, and Wyoming account  for over two-thirds of  the
Nation's total coal reserves; however, the most intensive mining
operations to date have been east of the Mississippi River (Figure  11).

Land in Farms

     Historically the United States consisted of a highly developed
agricultural society in which farmers were in the majority, representing
over 90 percent of the total population.  Farming was once a way  of life
among the American people.  Today farming is simply considered  another
big business.  The United States is currently dependent upon less than
6 percent of the total population for its food and fibre production.

     The trend over the last five years has  been toward fewer and larger
farms.  Larger farms tend to be more productive than smaller farms  due
to their better management techniques and intensive fertility programs.
The average size of farms has risen from 190 acres in 1945 to over  400
acres in 1970.  The greatest decline in numbers has been in farms of  less
than 100 acres.  In 1935 the number of farms peaked at approximately
6.8 million and has continued to decrease since to its current  level  of
2.5 million.-'- P-504  projections indicate that this trend will  continue
and the current figure will fall below the 2 million mark by the  year
1980 (Figure 12).  Table 24 summarizes the total number, acreage, and
average size of U.S. farms from 1900 through 1970.  The distribution  of
U.S. farms is extremely widespread with very little concentration in
any one specific area of the United States.

     The most rapid decline in total number  of farms since 1935 has
occurred in the Northeastern, Southeastern,  and Delta States.   These
areas experienced a 55 percent reduction in  farms while the Great Lakes,
Corn Belt, and Northern Plains States only experienced a 30 percent
decrease over the same period of time.21 p.25  Today 50 percent of  the
total land under cultivation is owned and operated by 5.5 percent of  the
farmers.21 p.23  The trend toward further concentration of farms  has, for
the most part, subsided.

                    DISCUSSION  AHO  IMPLICATIONS

     Historically, animal wa^' e aiiil  Hewac-^  -. 1 udge were once highly
regarded by farmers as  a primary so-.irce of  ,,l^nt- nutrients and organic
matter necessary to sustain  adequnt? leปe.lฃ oi  s<~>il fertility in culti-
vated lands.  It has only beer,  within the past  few decades that animal
waste and sewage sludge have gained  u it-io^sl  recognition as a waste
disposal problem.  The  reason for  this dramaLir  change in attitude
toward utilization of animal ^' <  !'  <"P been used for many

been limited because of then" 1 ov  i.'utripnt  corJent, slow and virtually
uncontrolled nitrogen release ch"!an eristics, and the high cost of
distribution and application Lol.iJ'ivc  ; >"  synthetics.  A farmer usually
thinks in terms of adding pounds of  nutrlent  per acre, but when contem-
plating the use of sewage sludge  or  animal  waste, he must think in terms
of adding tons of fjgr_tiliggr_mat^r_] al pp.r --Hire fo attain the same
relative degree of applied nutrients.

     In the United States the annual production  of animal, waste and sewage
sludge totals approximately  2 billion wet tons per year.  Animal waste
is by far the greater of the two,  acrmmring  for c-.rer 99 percent of the
total waste generated.  Approximately 80 percent of the animal waste falls
on open pasture or grazing land and  presents  few if any problems.  The
remaining 20 percent is found in highly concentrated quantities where
animals are held in confinement: for  irrensive feeding or marketing pur-
poses.  Recent estimates by  the U.S. Department  of Agriculture and others
indicate that at least  one-half to  tvo-thirds of all the beef cattle waste
generated in confined or concentraied areas is being returned to the land
as a supplemental source of  fertilizer or as  a soil conditioner.

-------
     Utilization of sewage sludge on the other hand is extremely low when
compared to that of animal waste.  This is due primarily to an increased
awareness of the general public concerning the adverse qualities commonly
associated with sewage sludge when improperly handled or applied to the
land (i.e., odor development, accumulation of toxic metals in soil, plant,
and animal life, pathogen survival, and the potential that exists for
disease transmission).  In actuality, the fears of the public are not
completely unfounded because many sludge utilization and disposal oper-
ations across the United States do have a track record of not being
properly monitored and managed and problems have developed.  If,
however, sludge is properly handled and applied to the land in accordance
with "accepted practices", there is little or no reason for the public
to be alarmed.  The Environmental Protection Agency is currently in the
process of publishing a technical bulletin on acceptable methods of
sludge utilization and disposal which should be of benefit in determining
what would be considered an acceptable practice.^3

     According to a recent EPA report, fewer than 25 percent of all the
sewage treatment plants in the United States of 1 million gallons per
day capacity or more are currently landspreading their sewage on a
routine basis.  Approximately 68 percent of those landspreading their
sludge have been doing so for less than 10 years.  Furthermore, it was
found that most sludge landspreading operations are conducted without
any means of monitoring for environmental effects.

     In view of recent shortages and higher cost of commercially pro-
duced fertilizers, it has been reported that utilization of sewage
sludge and animal waste has increased and will likely continue to
increase throughout the remainder of this decade.  Utilization is ex-
pected to remain at a high level until the availability of abundant
supplies of natural gas are once again restored or alternate sources of
energy are found to replace natural gas as a cheap source of hydrogen
in the production of anhydrous ammonia.  Most industrial experts do
not foresee the supply of natural gas being equal to demand now or in
the near future and therefore predict even higher costs and increased
demands for limited supplies of fertilizer products.

     The nitrogen content of digested sewage sludge and animal waste
typically ranges between 1 and 4 percent on a dry solids basis.  It has
been calculated that 40 to 50 wet tons of animal waste or dewatered
sewage sludge have a nitrogen content approximately equivalent to that
contained in an average ton of commercial fertilizer produced in 1973
(i.e., @ 20 percent nitrogen).  Moreover, substituting organic waste for
commercial fertilizer means that a farmer has to handle many times as
much bulk material, thus greatly increasing his fertilizer handling and
application costs.  In addition to the added cost of application, sewage
sludge and animal waste seldom contain nutrients in the proper ratio
consistent with that of a farmer's specific needs.  This becomes
especially important when assessing the potential market value of a
particular organic waste material as a low grade fertilizer.  Fertilizer

materials having different concentrations of nitrogen, phosphorous, and
potassium, but similar ratios, can generally be used interchangeably as
it is necessary to alter only the rate of application to attain the same
relative degree of applied nutrients.  If the ratio of primary nutrients
differs significantly, however, excesses and/or deficiencies in one or
more of the primary nutrients is likely to occur after prolonged appli-
cation.  Therefore, it is generally recommended that only enough organic
waste material be applied to satisfy the demand of the most limiting
nutrient being applied.  Table 25 displays the typical ratio of primary
nutrients among the various types of organic waste materials compared to
that of the average commercial fertilizer produced in 1973.

     In addition to its nutrient content, sewage sludge may also contain
high concentrations of heavy metals which may restrict or inhibit its
utilization on land.  In general, sludges with extremely high concentra-
tions of heavy metals should not be applied to agricultural lands.   To
assist in determining acceptable application rates or the utilization
potential of a specific sludge based upon its metals content, the following
formula has been developed by the U.S.D.A. Agricultural Research Service
as a guide for limiting the toxic metal addition to soils.23

     TOTAL SLUDGE APPLIED  =  	32.700 x C.E.C. of soil	
      (dry tons per acre)     ppm Zn + 2(ppm Cu) + 4(ppm Ni) - 200

     C.E.C. = Cation Exchange Capacity of the unamended soil in meg/100 g
              as determined by the sum of cations or equivalent method

     ppm = mg/kg dry weight of sludge

     The above equation takes into account the greater phytotoxicity of
Zn, Cu, and Ni by converting each to its Zn equivalency.  The - 200
adjusts for the increase in Cation Exchange Capacity of the native  soil
as a result of the added inorganic matter applied with the sludge.   The
soil C.E.C. relates to the characteristic of the soil to absorb excess
metal ions.  Soil pH is also a very important factor limiting the amount
of sludge that can be applied to a specific soil.  Generally speaking, a
pH of 6.5 or greater is recommended for sludge applications.24  in
addition, the cadmium to zinc ratio should not exceed 1:100. ^

     Approximately 500,000 to 800,000 tons each of nitrogen (N), phos-
phorous ^265) , and potassium (I^O) are potentially available from that
portion of the animal waste and sewage sludge not being applied to  the
land.  If all the available waste were to be applied to the Nation's
cropland and its total nutrient value realized, it would represent  a
potential national savings of 7, 15, and 18 percent in nitrogen, phos-
phorous, and potassium consumption annually.  The energy implications
of such a savings are significant; however, when placed in proper per-
spective, this savings has only a minor impact upon the overall national
consumption of energy.  According to Sweeten, a net energy savings  of
approximately 4.4 million BTU's per acre of harvested grain sorghum or
                                   55

or corn silage could be realized by using 10 dry tons of feedlot manure
in lieu of commercial fertilizers (maximum haul distance was assumed to
be 10 miles one way).25  The 4.4 million BTU's of energy saved is approx-
imately equivalent to that required in the commercial production of 200
pounds of anhydrous ammonia (the amount normally applied to grain sorghum
and corn silage).   Therefore it can be calculated that a net national
savings of approximately 0.12 percent of the natural gas or 0.04 percent
of the total energy consumed annually in the U.S. could be potentially
realized if all the available animal waste and sewage sludge were used
in lieu of commercially produced nitrogen.

     Most of the problems commonly associated with utilization and
disposal of sewage sludge and animal waste have been largely the result
of improper distribution and handling, rather than an inability or
capacity of nature to assimilate fully the vast quantity of waste
generated.  Assuming a very moderate application rate of 10 dry tons of
solids per acre per year, it is calculated that less than 5 million
acres of land would be required to handle adequately all of the avail-
able animal waste and sewage sludge generated in the United States each
year.  The land requirement for sewage sludge alone is less than 10
percent of this total acreage.  The combined acreage for both sewage
sludge and animal waste represents only 1.3 percent of the Nation's
total land area currently under cultivation.  On an assumed worst case
basis, it is estimated that all of the Nation's municipal waste (i.e.,
garbage, sewage sludge, and food processing waste) could be disposed of
on less than 5 percent of our Nation's cropland without harm to the
environment or the crop.26  Therefore, it does not appear that our
Nation need be concerned about having sufficient land available to
utilize fully the growing quantities of sewage sludge and animal waste
being generated annually.  The real problem is basically one of distri-
bution, economics, and public acceptance.

     All factors taken into consideration, it is highly unlikely that
cities will be able to afford to continue to haul their sewage sludges
greater and greater distances to "remote" areas; therefore, they will
have to rely more heavily upon utilizing their sludge in urban areas.
The use of composted, heat-dried, digested, or otherwise stabilized
sludge should be encouraged on park land, playgrounds, turfgrass,
nursery products, cemeteries, cropland, etc., whenever possible.  The
higher cost of fuel and the more stringent regulations being placed
upon ocean dumping and incineration are making sewage sludge utilization
practices more and more attractive to municipalities than ever before.
In addition, feedlot operators should be encouraged to maximize the
utilization of their animal waste on cropland as a partial substitute
for commercially produced fertilizers.  New feedlots should attempt to
locate their businesses in areas that are considered to be more in step
with animal waste supply-and-demand principles.  Alternate and innovative
ways to deal with these waste products should be developed (e.g., gas-
ification, refeeding, pyrolysis, and energy recovery systems).  Land-
spreading should only be considered as a partial solution to the waste
disposal problems of our Nation to be used in conjunction with other means
of utilization and disposal.
