NOT TO BE USED IN PLACE OF ON-SITE INVESTIGATION X]1B-Atencio-AzeILine complex, I to 3 pencent slopes. These nearly level to gently sloping soils are on alluvial fans and terraces. The soiLs formed in mixed alluvium from redbed shales and sandst'ones. ElevaLion ranges from 5,000 to 7,000 feet. The average annual pre- cipitation is about 14 inches, the average annual air temperature is about 4J degrees F., and the average annual frost-free period is about 110 days. The Atencio soil makes up abouL l{5 percent of the mapping unit and Lhe Azeltine soil about 45 percenl. Grave1 bars, which make up about 10 percent of the unit, occur in some areas. The ALencio soil is deep and well drained. Typically, the surface Iayer is dank reddish gray sandy loam about 5 inches thick. The subsoil- is sandy loam to gravelly sandy clay loam about ]B inches thick. The subsLratum is gravelly sandy foam that grades into sand, cobbl-e, and gravel at depths between 23 and 30 inches. Permeability of the Atencio soil is moderafely rapid. Effective rooting depth is 20 Lo 25 inches. Availabfe water capacity is low. Surface runoff is slow and the erosion hazard is slight. The Azel-Line soit is well drained. Typically, the surface layer is reddish gray grayelly sandy loam about 8 inches Lhick. The underlying layer ls reddish brown gravelly sandy loam about 10 inches thick. The substratum is calcareous sand, gravel, and cobble to depths of 60 i-nches or more. Permeabiliiy of Lhe Azeltine soil is moderately rapid. Effective rooting depth is about 18 inches. Available water holding capacity is very 1ow. Surface runoff is slow and Lhe erosion hazard is slight. X11B-At,encio-AzeItine complex These soils are used mainly for LivesLock grazlng and cropland. Alfalfa, ,smaI1 grains, potaloes, and grass-legume hay are the main erops Brown. Flooding is the main method used for applying irrigation water. Conservation practices that include grass waLerways and minimum tillage are necessary Lo avoid serious erosion losses. Cover crops or stubble mulching in dryland farming areas wilf also help to eliminate erosion losses. The native vegetation of these soils is mainly Indian ricegrass, western wheaLgrass, big sagebrush, and needleandthread. When the range condition deterioraLes, forbs and woody shrubs increase. When the range is in poor eondition, undesirabfe r+eeds and annual plants are numerous. Proper grazing management maintains and lmproves the range condition. Seeding is a good practice if Lhe range is in poor condition. Suitable plants for seeding are crested wheat- grass, western wheatgrass, and Bussian wildrye. For successful seedinS, a good practice is to prepare a seedbed and drill the seed. ReducLion in brush improves deteriorated range siles. " I{ildlife using these soils for habitat include pheasant, dove, rabbit, squirrel, and some deer. These species obtain iheir food and shelter mainly in the areas of cropland. These soils have good potential for community development or for use as source material. Special design must be used for the insLallation of sepLic tanks and leach fields due Lo seepage and the possibility of ground water pollution.
