1 X53 C <br />t ??• ? 3 -him loam, 3 .to 5 percent slope <br />This is a deep, well drained soil on gentle plains and alluvial fans at <br />elevations of 4400 to 5250 feet. It formed in mixed eolian deposits and <br />I parent sediments from a wide variety of bedrock. <br />Included in this unit are some soils that have sandy login or loamy sand unde <br />lying material. <br />- t <br />Typically the surface layer is a brown to pale brown loam about 10 inches <br />1 <br />thick. The underlying material is a light clay loam or loam about 28 <br />inches thick. The substratum, to a depth of 60 inches is a loam or <br />fine sandy loam. ' <br />`Ywr? Permeability is moderate. Available water capacity is high. Effeccive <br />rooting depth is 60 inches or more. Surface rkinoff is red ium and erosion <br />' hazard is moderate. <br />' Where irrigated this soil is suited to the cotnnonly grown crops in the <br />area. However, perennial grasses and alfalfa or close grown crops <br />should be grown at least 50 percent of the time. Close grown crops and <br />t pasture can be irrigated with contour ditches and corrugations. Furrows, <br />contour furrows and cross slope furrows will work on row crops. Sprinkler <br />' irrigati6n is also recom.nended. <br />' Minitnutn tillage and crop residue utilization will help control erosion. <br />Fertility maintenance is important. Crops grown on these soils respond <br />to fertilizer 8pp1iCatinn$ of phosphorous and nitrogen.
