10 <br /> moist; with weak, fine granular structure; soft very friable, <br /> slightly sticky moist and slightly plastic. It is relatively free <br /> of gravel or rock fragments and has a pH of 7.3-7.7. It is weakly <br /> or non-calcareous. The Ap horizon is 4-6" thick. <br /> There is a clear, smooth boundary to the subsoil. The B2 horizon, <br /> 6-12", is a strong brown (7.5YR4/4) , moist) , sandy clay loam; <br /> medium angular blocky to medium sub-angular blocky; moderately hard <br /> dry, friable moist; moderately sticky and moderately plastic, wet; <br /> with very few rock or shale fragments, slightly to strongly calca- <br /> reous and slightly alkaline (pH 7.4-7.8) . Roots readily penetrate <br /> this horizon. <br /> The C horizon (10"-36" depth range) dominately 12"-30", is a <br /> strong brown (7.5YR5/6) , dry sandy clay loam, dark brown (7.5YR5/4) <br /> moist; strongly calcareous; and slightly alkaline (pH 7.6-7.9) ; <br /> blocky to medium subangular blocky; moderately hard to moderately <br /> friable dry, friable moist; slightly sticky to slightly plastic <br /> wet. Shale and sandstone fragments may increase toward the lower <br /> part of paralithic contact. <br /> The Shavano soils overlie soft interbedded shale and sandstone <br /> formations at depths ranging from 18" - 36" but the more conanon <br /> depth to paralithic contact is 20-30". The soils are well drained, <br /> have slow to medium runoff and are moderately permeable above the <br /> paralithic contact. As mapped, these soils are darker in the <br /> surface and probably receive more precipitation than typical of <br /> Shavano soils (See official series description by S.C.S. , AJC, 4/73) . <br /> They are used as irrigated cropland and seeded pasture. Native <br /> vegetation would include sagebrush, Galleta grass, needlearass, <br /> stipas and forbs. <br /> 5810 Topsoil Suitability. These soils will supply most of the <br /> topsoil for the 116-acre tract. Quality to an average of 18" in <br /> the smoother slopes and 12" on the steeper slopes is good. Cuts <br /> can be made to 24" on gentler slopes and 20" on steeper slopes <br />
