<br />100 - Satanka silt loam, deep phase, 3 to 10 percent slopes. <br />The Satanka, deep phase soil is moderately deep to deep and well-drained. <br />It developed from aeolian deposits and alluvium on lea sides of ridges. Small <br />areas of Turfy Variant and Satanka soils were included in mapping. Turley Variant <br />soils are deep to vary deep. Satanka soils are moderately deep. Ihese soils occupy <br />less than 15 percent of the mapping unit. <br />In a typical profile, the surface layer is pale brown silt loam about 3 <br />inches thick. The upper subsoil is light yellowish brown loam about 9 inches <br />thick. The lower soil is very pale brown calcareous loam about 12 inches thick <br />and is underlain with fractured sedimentary rock at a depth of 30 to 50 inches. <br />The Satanka soil has moderate permeability and medium runoff. The erosion <br />• hazard is low to moderate from water and moderate to high from wind. Available <br />waterholding capacity is moderately high. Effective rooting depth is 20 to 40 <br />inchas. <br />This soil is used for livestock grazing and wildlife habitat. Tha vegetation <br />is primarily big sagebrush and mixed perennial grasses with areas of cheatgrass. <br />The average depth of suitable topsoil material is 35 inchas. The material <br />is rated fair to good with suitability decreasing with depth. <br />u <br />
