72C-Unnamed sandy loam <br />Permeability of this soil Ss moderately rapid. Effective rooting depth , <br />is 60 inches or more. Available water capacity is moderate. Surface <br />runoff is slow and erosion hazard is moderate. <br />This soil is used for cropland, hayland, and livestock grazing. <br />'.. <br />Corrugation or flooding is the usual method of irrigation. Sprinklers <br />are a good method of irrigating on this soil. tfini~mum tillage, grass <br />waterc:ays, and tail=water control will help prevent erosion. Drop <br />structures in ditches help control water and reduce erosion. <br />The native vegetation on this soil is dominated by western wheatgrass, <br />streambank wheatgrass, bluebunch wheatgrass, Indian ricegrass, squirrel- <br />tail, fourwing saltbush, winterfat, and big sagebrush. When the range <br />condition deteriorates (orbs, weedy annuals, and woody shrubs including <br />greaseuood and snakeweed increase. <br />Grazing management will improve deteriorating range conditions: Seeding <br />is advisable if the range is in poor condition. Suitable for seeding <br />are Russian wildrye, western wheatgrass, crested wheatgrass, and Indian <br />ricegrass. The grasses selected should meet the sc~sonal requirements <br />of livestock. For successful seeding, prepare a seedbed and drill the <br />seed. Brush management may be required to improve deteriorated sites <br />_ that are producing more woody shrubs than noc•mally found in the potential <br />plant community. <br />_ ._ I-12 <br />
