This soil is used almost entirely for irrigated crops. It is suited to all corps commonly <br />grown in the area, including corn sugar beets, beans, alfalfa, small grain, potatoes, and <br />onions. An example of a suitable cropping system is 3 to 4 years of alfalfa followed by <br />corn, corn for silage, sugar beets, small grain, or beans. Few conservation practices are <br />needed to maintain top yields. <br />Windbreaks and environmental plantings of trees and shrubs commonly grown in the azea <br />are generally well suited to this soil. Cultivation to control competing vegetation should be <br />continued for as many years as possible following planting. Trees that are best suited and <br />have good survival are Rocky Mountain juniper, eastern redcedaz, ponderosa pine, Siberian <br />elm, Russian-olive, and hackberry. The shrubs best suited aze skunkbush sumac, lilac, <br />Siberian peashrub, and American plum. <br />Wildlife is an important secondazy use of this soil. The cropland azeas provide favorable <br />habitat for ring-necked pheasant and mourning dove. Many nongame species can be <br />attracted by establishing areas for nesting and escape cover. For pheasants, undisturbed <br />nesting cover is essential and should be included in plans for habitat development, <br />especially in areas of intensive agriculture. <br />This soil has fair to poor potential for urban development. It has moderate to high shrink- <br />swell, low strength, and moderately slow permeability. These features create problems in <br />dwelling and road <br />construction. Those areas that have loam or sandy loam in the lower part of the substratum <br />are suitable for septic tank absorption fields and foundations. Some areas of this soil are <br />adjacent to streams and are subject to occasional flooding. The potential is fair for such <br />recreational development as camp picnic areas and playgrounds. Capability class I <br />irrigated. <br />63 -Terry Fine Sandy Loam, 3-9 % slopes <br />This is a moderately deep, well drained soil on plains at elevations of 4500 to 5000 feet. It <br />formed in residuum from sandstone. Included in mapping are small azeas of soils that have <br />sandstone deeper than 40 inches. Also included are small areas of soils that have a sandy <br />clay loam and clay loam subsoil. <br />Typically the surface layer of this Terry soil is pale brown fine sandy loam about 6 inches <br />thick. The subsoil is pale brown fine sandy loam about 18 inches thick. The substratum is <br />Fine sandy loam. Sandstone is at a depth of about 32 inches. <br />Permeability is moderately rapid. Available water capacity is moderate. The effective <br />rooting depth is 20 to 40 inches. Surface runoff is medium to rapid, and the erosion hazazd <br />is moderate. <br />This soil is suited to limited cropping. Intensive cropping is hazardous because of erosion. <br />The cropping system should be limited to such close grown crops as alfalfa, wheat, and <br />barley. The soil is also suited to irrigated pasture. A suitable cropping system is 3 to 4 years <br />of alfalfa followed by 2 years of com and small grain and alfalfa seeded with a nurse crop. <br />F[ Lupton Pit <br />DMG ll2 Permit <br />Page 47 oj81 <br />
