In irrigated areas this soil is suited to all corps commonly grown in the area, including corn, sugar beets, beans, alfalfa, small grain, and onions. An example of a suitable cropping system is 3 to 4 years of alfalfa followed by corn, corn for silage, sugar beets, small grain, or beans. Land leveling, ditch lining, and installing pipelines are needed for proper water applications. All methods of irrigation are suitable, but furrow irrigation is the most common. Barnyard manure and commercial fertilizer are needed for top yields. Windbreaks and environmental plantings are generally suited to this soil. Soil blowing, the principal hazazd in establishing trees and shrubs, can be controlled by cultivation only in the tree row and by leaving a strip of vegetation between the rows. Supplemental irrigation may be necessary at the time of planting and during dry periods. Trees that are best suited and have good survival are Rocky Mountainjuniper, eastern redcedar, ponderosa, pine, Siberian elm, Russian-olive, and hackberry. The shrubs best suited are skunkbush sumac, lilac, and Siberian peashrub. Wildlife is an important secondary use of this soil. The cropland areas provide favorable habitat for ring-necked pheasant and mourning dove. Many nongame species can be attracted by establishing azeas for nesting and escape cover. For pheasants, undisturbed nesting cover is essential and should be included in plans for habitat development, especially in areas of intensive agriculture. Rangeland wildlife, for example, the pronghorn antelope, can be attracted by developing livestock watering facilities, managing livestock grazing, and reseeding where needed. This soil has good potential for urban and recreational development. lawns, shrubs, and trees grow well. The only limiting feature is the rapid permeability in the substratum, which causes a hazard of ground water contamination from sewage lagoons. Capability subclass lie irrigated; IVe noninigated; Sandy Plains range site. 82 -Wiley-Colby complex, 1-3 % slopes This neazly level map unit is on smooth plains in the western part of the survey area at elevations of 4850 to 5000 feet. The Wiley soil makes up about 30 percent. About 10 percent is Heldt silty clay and Weld loam. The Wiley soil is deep and well drained. It formed in calcazeous eolian deposits. Typically the surface layer is pale brown silt loam about 11 inches thick. The subsoil is pale brown silty clay loam about 23 inches thick. The substratum to a depth of 60 inches is very pale brown silty clay loam. Permeability is moderately slow. Available water capacity is high. The effective rooting depth is 60 inches or more. Surface runoff is medium, and the erosion hazard is moderate. Ft Lupton Pit DMG /11 Pesmit Page so ols/
