Uee of nitrogen end phosphorus fertilizer promotes good growth of forage plants. Proper stocking rates, pasture rotation, and restricted grazing during vet periods helps to keep the pasture in good condition and to protect the soil from erosion. Steeper areas of this unit are not suited for irrigation systems. If properly managed this unit can produce 4 tone of irrigated grass hay per acre.

Ocher less numerous plants [hat characterize this unit are native bluegrass, green needlegrass, and little blues tem. The.average annual production of air-dry vegetation is about 1300 pounds per acre. If the condition of the range deteriorates, sleepygrass, ring muhly, cholla, and tall rabbitbrush increase. Range seeding is suitable if the range is in poor condition. If this unit is used for nonirrigated cropland the main limitaticns are hazard of erosion, steepness of slope, and insufficient annual precipitation. Yliieat and oats are the main crops. Because precipitation is not sufficient for annual cropping, a cropping system chat includes small grain and summer faliov is most suitable. Maintaining crop residue ~ on or near the surface reduces runoff, reduces soil blowing, and helps to maintain soil filth and organic matter content. Crops respond to nitrogen and phosphorus fertilizer. Soil blowing can be reduced by planting crops in alternate scrips and at right angles to the prevailing wind. This unit can produce 18 bushels of wheat Sn a vl~cat-fallow cropping system.
