-- ~ -- <br />5511-Eaplustolls - Loamy, Moderately Steep <br />DRAFT <br />7-77, AEA <br />This is a complex of shallow to moderately deep, stony, well <br />drained soils on moderately steep hogback areas. They are forming in <br />story sandy loam and loam materials derived from sandstone (Lykins <br />_°ormation). The average annual precipitation is 17 to 19 inches, <br />frost free season is 125 to 140 days, mean annual air temperature is <br />47° F. Elevation ranges from 6000 to 5500 feet. Slopes are 15 to <br />,0 percent. <br />Included in this unit are small areas of rock outcrop and areas <br />of sandy loam soils that are deeper than 40 inches over bedrock in <br />the slope and cove-like positions. <br />Typicall;r, the surface layers are grayish brown stony sandy loans <br />about 4 inches thick.. The subsoils are brown sandy loans. Depth to <br />sandstone varies from 10 to 40 inches. <br />Permeability is moderately rapid, available water capacity ranges <br />from low on the shallow soils to moderate on the medium depth soils. <br />Effective rooting depth varies from 10 inches to 40 inches. Surface <br />runoff is high, water erosion hazard is high. These soils are neutral <br />to mildly alkaline, <br />These soils are used mainly for grazing, recreation, wildlife <br />and limited urban development. <br />Plant Adaptation: The stony surface layers, shallow depths, and <br />slope are the primary limitations. Special care and measures are re- <br />quired to compensate for these limitations. Backfilling shallow areas, <br />incorporating plant residues into surface layer, and grading slopes are <br />effective measures aiding establishment of plant and g: ass cover. <br />Community Development: Sloge and soil depth are primary limita- <br />tions for urban development. Areas used for development require special <br />design. <br />Capability Class: VIIs. <br />Range Site; Shallow Foothills. <br />I~ydrologic Group: B. <br />Plant Adaptability Group: F. <br /> <br /> <br />
