<br />137 - Redcreek-Rentsac complex, 5 to 30 percent slopes <br />This complex occurs on ridgetops and side slopes and developed from calcareous <br />residuum with relatively high coarse fragment content. It is co.npris~d of about <br />50 percent Redcreek soils and 35 percent Rentsac soils. Small areas of ~4oyerson <br />soils and rock outcrop were included in mapping. ,doyerson soils are shallow and <br />fine-textured. These included soils and rock outcrop occupy less than 15 percent <br />of the unit. <br />'The Redcreek soil is shallow, coarse-textured and well-drained. In a typical <br />profile, the surface layer is pale brown loam about 4 inches thick. The subsurface <br />soil is pale brown sandy loam about 4 inches thick. Thz substratum is very pale <br />brown calcareous loam about 8 inches thick and is underlain with slightly <br />fractured calcareous loamstone at a depth of 16 inches. <br />• 'The Redcreek soil has moderate permeability and medium runoff. Thz erosion <br />hazard is moderate to high from wind. Available waterholding capacity is moderate. <br />Effective rooting depth is 10 to 20 inches. <br />The Rentsac soil is shallow, skeletal and well-drained. In a typical profile, <br />the surface layer is light yellowish brown loam about 3 inches thick. 'The <br />subsurface layer is very pale brown calcareous vary channery loam about 3 inches <br />thick. The substratum is very pale brown calcareous very channery clay loam about <br />7 inches thick and is underlain with highly fractured calcareous loamstone at <br />a depth of 13 inches. <br />The Rentsac soil has moderate permeability and medium runoff. The erosion <br />hazard is low to moderate from wind and water. Available waterholding capacity <br />is moderately low. Effective rooting depth is 10 to 20 inches except for juniper. <br />• <br />
