                          INTRODUCTION
The Western Environmental  Research Laboratory of the Environmental
Protection Agency maintains an experimental  research farm on the
Nevada Test Site.  The farm is located approximately 110 miles north
of Las Vegas in Area 15 of the Nevada Test Site (see Figure 1),
and is situated in a high desert valley (4,500 feet elevation).
The soil  is a coarse, gravelly, sandy loam with cobbles intermixed,
and  has a pH of approximately 8.3.  Physical description and history of
                                                 (1 2)
the farmstead are covered in the previous reportsv  '  .

This is a continuing report of the agronomy practices of the experimental
farm for the year 1970.  It is compiled from monthly reports that are
written from daily records kept by the Crop Research Helpers.  These
records document the practices on the farm and supply information that
can be used in support of controlled release experiments or in "Ad Hoc"
studies that are mounted following any accidental  releases from an under-
ground test or releases from reactor testing conducted  at the Nuclear
Reactor Development Station.

                           IRRIGATION
The irrigation season runs from April  through  October.   The  total
amount of water applied was 84.8 acre feet (325,850  gallons  or  1,205,645
liters equals one acre foot) with an average of  5.3  acre feet per land.
A land is the area between two irrigation  laterals and  is approximately
one acre.  The amounts of water applied to each  land each month are
shown in Appendix I.

During 1969, 84.4 acre feet of water with  an average of 5.2  acre feet of
water per land was used.  The irrigation period  for  1969 and 1970 was
applied in the same amounts^  .  Figure 2  shows  a comparison between 1969
and 1970 by months.

During the past three years the amount of  irrigation water applied per
acre has been approximately the same each  year.   In  1968 5.8 acre feet
were applied, in 1969 5.2 acre feet were applied, and in 1970 5.3 acre
feet per acre were applied for an average  of 5.4 acre feet per  acre.

                         FERTILIZATION
The two fertilizers used during 1970 were ammonium sulfate 21-0-0 and
trebel superphosphate 0-45-0.  Phosphorus was applied to the alfalfa  in
March at the rate of 144 pounds PgOg per acre (63.4  pounds of P/acre).
The two grass and legume lands, 10 and 14, had 36 pounds P20^ per acre
(15.8  pounds of P/acre) during the year.

Lands 10 and 14 had applications of 96 pounds N and 80 pounds N,  respective-
ly.  These amounts were made in two applications.  Lands 15 and 16 had
applications of 42 pounds N and 36 pounds P205 (15.8  pounds P) and Land
17 received 16 pounds N during April.

Preplant applications of nitrogen and phosphorus were made on the small
grain in October.  Lands 15 and 16 each had an application of 73 pounds N
per acre and 36 pounds P205 per acre (15.8 pounds of P/acre), Land 17 had
21 pounds N per acre and 18 pounds PgOg per acre (7.9 pounds of P/acre).
The nutrients and the amounts applied to each land are shown in Appendix II.

-------
                       AGRONOMY PRACTICES
A.  Land Preparation and Seeding
    Lands 15, 16, and 17 were enisled to a depth of 12-14 inches,
    disced and spike-tooth harrowed and leveled with a drag float  to
    prepare seed beds for rye grain.   Preplant fertilizer was  applied
    in October.  The amounts and types have been covered under fertili-
    zation.

    On October 9, Secale cereale, Elbon variety rye was planted.
    Excellent germination occurred and a thick stand was established.
    The rate of seeding was 100 pounds to the acre.

B.  Harvesting
    The rye grain was green chopped on March 27.  This is the  earliest that
    green chopping has occurred at the experimental farm in five years of
    harvesting green feed.

    The small grain that was utilized for green chop was Elbon rye.   This
    is a winter hardy variety that has been used for the last  four years.
    Harvesting of alfalfa green chop began on April 17 and continued
    through November 3.

    The harvesting season lasted a total of 221 days with production of
    171.1 tons (10.7 tons per acre or 1548.4 pounds per day wet weight)
    on 16 acres.  Appendix III shows the green chop produced during  the
                                  6

-------
    months on each land.

    Hay production was  lower this year than  the  preceeding  year  in  spite  of
    the long growing season, it was  not a year conducive  to alfalfa production.
    The average was 2.36  cuttings per acre.   In  previous  years there were four
    to five cuttings.   The hay produced was  of excellent  quality,  grade U. S.
    No. 1  leafy alfalfa hay.  Appendix IV shows  the hay production  per month
    from the hay production lands.
                                      t>

    The amount of hay produced was 47.2 tons on  11  acres  with an average  of
    4.3 tons per acre.   Of the 14 acres of alfalfa, 3  were  utilized only
    for green chop and  the other 11  acres were utilized for both hay and  green
    chop.

    The hay is produced from stands  that are four to five years  old.  The
    stands are thick and  show no signs of thinning out.  The alfalfa that
    is grown is Medicago  sativa, Lahonton variety.

C.  Weed Control
    Both chemical and mechanical means were employed in the control of weeds.
    The mechanical control in the noncrop areas  consisted of uprooting the
    growing weeds with a  rear-mounted blade on a tractor.  This  was done  when
    the weeds were two to six inches high.  This method has to be repeated a
    number of times during the season.

    Two herbicides were used on the vegetable plots in the  microplots. These
    were preplant EPTC (Eptam) ethyl di-n-propyl thiol carbomate, a selective
                                    7

-------
herbicide and DCPA (Dacthal), a phthalic compound dimethyl ester of
tetra chlorotere-phthalic acid.  The herbicides gave good weed control
during the season.  Some hand hoeing was required in the microplots as
barn yard manure had been applied to these plots in previous years
which resulted in a weed infestation.  During this season no manure
was added and the plots are being cleaned of weeds.  Along the irriga-
tion laterals and fence rows chemical weed control was used.  The
chemicals used during 1970 were Rad-E-Cate (Cacodylic acid), Paraquat
                                   «
(Dimethyl-bipyridyliumion), 2-4 Dichlorophenoxyacetic acid and diesel
fuel oil.  Only weed free  seed is sown on the farm which keeps down
the introduction of noxious weeds.  None of the hard-to-
control weeds such as Russian knapweed, Canadian thistle or bindweed
are present.

The three small grain lands, 15, 16, and 17, that were in summer fallow
were disced three times during the summer to control the weeds.

During the 1970 season no infestations of harmful insects occurred and
no chemical insect control methods were required in the crop production
area of the experimental farm.

-------
                       IODINE EXPERIMENTS
Project Washout was conducted on September 29, 1970.  Land 5 was utilized
for the experiment.  The primary purpose of this project was to study, under
controlled conditions, the efficiency of the washout process for removal
of iodine in various forms by various intensities of rain.  Dry    I labeled
diatomaceous earth and elemental iodine were generated to pass over experi-
mental plots of growing alfalfa.  A precipitation was generated over certain
of these plots during the aerosol passage.

Contamination levels, precipitation levels, size distribution of the
aerosol particulates, as well as the precipitation droplets, and the
deposition parameters were determined.

Two groups of three cows each were used.  One group was fed green chop
harvested from the washout plot and one fed dry contaminated green chop
to determine the milk secretion parameters.  A third group, the control,
was fed noncontaminated green chop.  Included in this experiment was a
determination of the relative T ^ in plants between the dry and washout
situations.  The data from this study will be used with those of previous
                                                            t
projects of this series as input to an exposure-dose model for the radio-
iodines.

Project Washout was the only experiment conducted during 1970 that utilized
forage produced on the farm for other than routine feeding operations.

-------
                             MICROPLOTS
The existing irrigation system was taken out.   The portable aluminum
irrigation system was replaced with permanent main lines and laterals.
Rain Bird "35A" adjustable heads, capable of delivering 7.5 gallons per
minute at 50 PSI were installed on the laterals.   By installing a bypass
and hooking on to the microplots main line, it was possible to utilize
the main field irrigation pump to deliver the water to the microplots.
The new system gives more efficient utilization of water, time, and
labor.

The microplots were chisled to a depth of 12-14 inches to break up a hard
pan that had developed, the field was cross disced four times then disced
and spike-tooth harrowed to form a good seed bed for the small grains and
vegetables that were planted.

Pre-emergence herbicides were used on the vegetables.  Eptam was used on
the beets, peas, and black-eyed peas.  Dacthal was used on Swiss chard,
head lettuce, onions, and watermelons.  The Eptam seemed to have ah effect
on the red beets in that the beets germinated, emerged and died.  The
dying back appeared to be similar to "damping off" so it was not positive
that the losses of the beets were due to the herbicides.  Damping off is
a disease of seeds or young seedlings caused by fungi.
Wheat was planted on May 14.  Ramona 50 was the variety planted.  The wheat
was harvested in August with a yield of 42 bushels (2,520 pounds) per acre.
                                  10

-------
A higher yield probably would have been realized had the wheat been
planted earlier.  The alfalfa in the microplots was utilized for green
chop.

Samples of the grain and vegetables grown on the microplots were taken
and analyzed for tritium concentration.  The analytical  results are
shown in Appendix V.

                  COMPARISON OF SURROUNDING AREAS
The amount of green chop produced in the Moapa Valley during 1970 from
an October 1 planting is:    oats, 4.5 tons; barley, 5 tons; and wheat,
5.3 tons.  Yield of green chop is expressed in tons per acre dry matter,
as the dry weight is approximately 30% of the wet weight.  A conversion
of the 10.7 tons per acre wet weight gives the average dry weight of the
green chop produced on the experimental farm as 3.6 tons per acre, this
includes both alfalfa and small grain green chop.  '

Alfalfa hay production in Southern Nevada averaged 8 tons per acre produced
in six cuttings.  Lahontan variety yielded 7 tons at Reno in 4 cuttings.
This variety is the one that is grown at the experimental farm.  Lahontan
alfalfa at Knoll Creek, Elko County, Nevada (elevation 5,600 feet) during
a three-year period averaged 3.1 tons per acre on three cuttings.  The
alfalfa production at the farm was 4.3 tons per acre on 2.4 cuttings per
acre.'5'6'

Farming operations at the experimental farm follow as closely as possible the
recommended practices of commercial farm operations in Nevada and surrounding areas,
