ERO Resources <br />Table I-1 and have the general suitability charaoteristios for the <br />• apeoific class or range of classes as disoussed in Section ]2.a.11) <br />through 12.a.(3) below. <br />(1) Clara 2; <br />Clare 2 soils have 20 to 40 inches of fair topsoil material. These soils <br />are moderately deep to bedrock. <br />The Class 2 soil series in the B Portal area are Cushman and Boettcher. <br />These soils have A horizon textures of silt loam, the B horizon is silty <br />olay loam to silty clay and the C horizon is silty olay loam to clay. <br />They are well-drained with madiun runoff and slow to moderate <br />permeability. They are nonsaline, nonalkaline and the wind and water <br />erosion hazard is moderate to high. Tilth at optimuw moisture cornern is <br />fair. The potential for compaction is moderate. Soil structure has fair <br />stability when wet. The potential for crusting upon drying ie moderate. <br />Available water holding capacity is moderate. Effective rooting depth is <br />• typically 30 to 40 inches. <br />(2) Clara 3; <br />Class 3 soils have 10 to 20 inches of fair topsoil material. These soils <br />are shallow to bedrock or paralithio contact. <br />Class 3 soil series in the B Portal area are Moyerson, Redoreek and <br />Rernsac. These soils have loamy to fine textures typically ranging from <br />sandy loam to silty clay. Many of the soils are intermixed with rock <br />outcrop and have high peroentages of rook fragments near the surface. <br />Class 3 soils are well-drained with medium runoff and clove to moderate <br />permeability. They are nonsaline and nonalkallne throughout. Nind and <br />water erosion hazard is moderate to high. Tilth at optimum moisture <br />oontent is fair to good, the potential for ooepaotion varies from low to <br />moderate, Soil structure has fair Lo good stability when wet. The <br />• potential for orusting upon drying i• low to naderaty. Available water <br />II,I- 8 <br />
