Feed Production 7 ------- INTRODUCTION The Environmental Monitoring and Support Laboratory-Las Vegas (EMSL-LV) of the U.S. Environmental Protection Agency (EPA) maintains and operates an experimental dairy farm on the U.S. Energy Research and Development Adminis- tration's (ERDA) Nevada Test Site (NTS). The Farm and Animal Investigation Branch (MSF) of the Monitoring Systems Research and Development Division is responsible for the operation of the farm and for assisting in or carrying out the related research activities. This farm is located approximately 110 miles north of Las Vegas in Area 15 of the NTS and is situated in a high desert valley at an elevation of about 4,500 feet (see Figure 1). The history and physical description of the farm fl 234} were reported previously.v ' ' ' ' As depicted in Figure 2, the experi- mental farm consists of 16 acres of irrigated cropland divided into 17 plots or lands by the irrigation laterals. Each of the end lands has an area of approximately h acre, while the remaining 15 lands each contain 1 acre. The soil is typed as coarse, gravelly, sandy loam with cobbles intermixed, low in organic matter, nitrogen, and phosphorus, and moderately high in potas- sium. It has a pH of 8.3.^ Adjacent to the northeast corner of the farm is approximately 2% acres of small irrigated crop areas called "microplots." These microplots are used to study the behavior of pollutants in soils and the uptake, retention, and residence time of these pollutants in various crops. This report, covering calendar years 1971, 1972, and 1973, is one of a series that describes the agronomic practices at the experimental farm. It was prepared from records maintained by MSF farm personnel to document those practices and to supply information for planned experiments and special ad hoc studies. ------- EXPERIMENTAL BUFFER ZONE Nuclear Rocket Development Station / SCALE IN FEET ' SCALE IN METRES 10OOO O 300OO O 5OOO 10OOO Figure 1.

Layout of the Experimental Dairy Farm. ------- AGRONOMIC PRACTICES LAND PREPARATION SEEDING Lands 1 through 9, 11, 12, and 13 are maintained as permanent alfalfa plots; lands 10 and 14 are planted to alfalfa and grass; and lands 15, 16, and 17 are used for small grain crops for early spring green feed production. Every year in late summer these latter three lands are chiseled to a depth of about 12 inches, disced, and harrowed to prepare a seed bed for rye grain. A preplant fertilizer of nitrogen and phosphorus is applied. The fertilizer application rates are described in another section. Secale cereale, "Elbon" cultivar rye seeds were planted at the seeding rate of 120 pounds per acre on September 23, 1971, September 27, 1972, and October 2, 1973. IRRIGATION Annual rainfalls for the years 1971, 1972, and 1973 were 6.79, 6.34, and 8.69 inches, respectively (see Appendix A-l). As this natural precipitation was not sufficient for crop production, irrigation water was supplied by a sprinkler irrigation system. Irrigation water was pumped from a 1-million gallon capacity reservoir which "is supplied by a 5,400-foot deep well. The well pump was set at 1,700 feet and pumps at the rate of 200 gallons per minute. The monthly irrigation rates for each land are listed in Appendix B. Total annual precipitation and irrigation are summarized in Table 1. Monthly tempera- ture ranges for these years are shown in Appendix A-2. Table 1.

Phosphorus was applied during the winter months as a top dressing for the crops and was also applied to small grains as a fertilizer prior to planting to aid in root development. Small grains and grasses required nitrogen for plant growth. This was applied as a top dressing during the growing season and as a fertilizer prior to planting on small grains. No additional nitro- gen fertilizer was applied to the alfalfa. Alfalfa, a member of the Leguminosae family, has the characteristic of forming nitrogen-fixing nodules on its roots enabling the use of atmospheric nitrogen. Table 2 lists the nutrients applied to each land, and the year and month of the applications. HARVESTING Nearly all the forage produced during the growing season is used as green feed. When the growth exceeds the demand for green feed, the forage is cut and baled as hay. The details of the feeding procedures are presented in another report. ' A summary of the feed production for the 3 years is given in Table 3. Forage production for each land by monthly and yearly totals is shown in Appendix C. Figure 3 depicts the annual production of green feed on an air-dried basis and hay from 1966 through 1973. WEED CONTROL Mechanical and chemical means were both employed to control weeds. In order to prevent reseeding, weeds in the non-crop areas were uprooted with a rear-mounted tractor blade when they were 2 to 6 inches high. This was repeated when necessary. After the spring harvest of the small grains, the lands were left fallow until the fall reseeding. Weed control of the lands consisted of two to three discings during the summer months. ------- Table 2.

The herbicides were applied at the manufacturer's recommended rates. During 1973, the soil sterilant Ureabor (sodium metaborate tetrahydrate, sodium chlorate, and bromacil) was applied around the sprinkler heads where it is difficult or impossible to clip. Only certified weed-free seed was planted to prevent the introduction of noxious weeds. INSECT CONTROL No infestation of insects occurred during 1971; therefore, no control methods were necessary. During March 1972, a heavy infestation of pea aphids occurred in the alfalfa in lands 1 through 14. Complete control was achieved after two sprayings of Malathion E56 at 6-day intervals (1 pint of Malathion in 20 gallons of water was applied to each acre). During March 1973, a heavy infestation of pea aphids occurred again in the alfalfa in lands 1 through 14. Complete control was achieved after sprayings of Diazinon AG500 at 7-day intervals (1 pint of Diazinon in 20 gallons of water was applied to each acre). 7 ------- 170- 160- 150- 140- 130- 120- 110- 100- ĞA 90- 70- 60- 50- 40- 30- 20- 10- oJ 1 ^. ^ m \ \ I Y////A m * 1 I ( m E* E* t * E* > E* t EC * * * iREEl 'S/////////A 1 M ^^i I* * * * * # # ğ * * ğ i FEED E r S HAY n K ^ N ^ r ^ r ra * * * * * I I B ra 1966 1967 1968 1969 1970 1971 1972 1973 Figure 3. Forage Production (air-dried) from 1966 through 1973. 8 ------- In June 1973, a heavy infestation of lygus bugs (a sucking insect) occur- red in the alfalfa. Harvesting of the alfalfa and the presence of a large number of natural insect predators (ladybugs) resulted in control of this insect. ------- RESEARCH STUDIES AT THE MICROPLOT AREA During the summer of 1971, selected vegetable crops were grown on the micro- plot area to determine the relationships between the concentration of tritium in the soil and the tritium concentration in the free water of the plants growing to\ in this soil. ' Plant tissue tritium concentrations were generally higher than the soil tritium concentrations. In some instances, the concentrations in plant tissues were double those found in the soil samples. This may have resulted from foliar absorption of atmospheric tritium which probably originated from the Sedan Crater located about 2 miles south of the experimental farm. During 1972, alfalfa was grown in the glasshouse located on the microplot area. Personnel from the MSF, under the direction of the Pollutant Pathways Branch (MSP), maintained the alfalfa growing in tritiated water at a specific activity of 100 nCi/ml of water. The alfalfa produced was used as rabbit feed for Project Triton. The results of this project were presented at the meeting of the Fifth International Congress of Radiation Research in 1974.^ ' During 1972, the microplot area was used by the MSP for an investigation entitled, "Mercury Behavior In An Agricultural Environment." Using mercury-203 as a tracer, measurements were made of the root uptake, retention, and trans- location of this environmental pollutant by table beets, barley, green beans, and lettuce, and of foliar absorption and retention of mercury by alfalfa, barley, and lettuce. The behavior and migration of mercury in soils were also studied. During the 1972 experiment, it was noted that approximately 75% of the applied mercury volatilized. An experiment was conducted in 1973 by the MSP on the microplot area to study the volatilization and to evaluate the potential use of plants as biological monitors of mercury. Reports concerning these two projects have been published.' ' ' 10 ------- PUBLIC RELATIONS Because of the uniqueness of an operating dairy farm located on the NTS, it is frequently visited by groups on orientation tours of the NTS. During the 3 years covered in this report, approximately 80 groups totalling 2,500 people visited the farm and were briefed on the activities of the farm and its role in the surveillance and research programs conducted by the Environmental Monitoring and Support Laboratory-Las Vegas. 11 ------- SUMMARY The procedures employed at the experimental farm either follow practices recom- mended by the University of Nevada Experiment Station and Cooperative Extension Service or duplicate actual practices used by commercial farmers of this general geographic area. Direct comparisons of yield, fertilization needs, and water requirements are difficult as the farm is isolated and not part of any specific farming area. Each area has its unique characteristics which influence the agronomic practices and determine, to a great extent, crop yields. Some of these characteristics are fertility, soil pH, so-il type and depth, organic content, altitude, length of growing season, amount of precipitation, and quality of irrigation water. However, based on data available for the nearest farming areas, the experimental farm appears to correspond well with the yields and requirements of surrounding similar operations. For example, the average green feed production from small grains in the Moapa Valley (an agricultural area 100 miles southeast of the Area 15 farm) was 4.9 tons/acre (air-dry basis), while the 1971-1973 production from rye grain at the Area 15 farm was 5.1 tons/acre (air-dry basis)." ' While application of irrigation waters has not changed significantly (1966 usage averaged 4.8 acre feet/acre vs. 4.9 acre feet/acre in 1973), production of green feed has increased markedly. During 1966, the average production was 3.7 tons/acre and, during 1973, it was 25.5 tons/acre. This increase is partially the result of plant maturity and increased soil fertility, and is partially because of changes in feeding procedures. During 1966, only enough green feed was harvested to feed the lactating cows, while in 1973, the entire herd (lactating and dry cows, replacement heifers, calves, and miscellaneous beef animals) was maintained on fresh harvested forage. Since 1967, excess forage has been harvested as hay; prior to that time, it was used as mulch. 12 ------- REFERENCES 1. Daley, E. M. and Smith, D. D. Agronomic Aspects of the Experimental Dairy Farm.
