Included with this soil in <br />maDPinq are a few small areas of soils that are more or <br />less sloping, a i`ev small areas of soils that ha e-e a <br />surface layer of clay loam, and a few small areas of <br />soils that hate gravel on the surface. Also included <br />are a small areas of Fnrt Collins and Stoneham soils. <br />A water table is within the roof zone for part of the <br />growing season in a few areas. The Kim series consists <br />of deep, well drained soils that formed in mixed <br />alluvium. Typically, the surface layer is a loam about <br />12 inches thick. The underlying material is loam about <br />38 inches thick. Permeability is moderate, and the <br />available water holding capacity is high- Reaction is <br />mildly alkaline above a depth of 12 inches and <br />moderately alkaline below that depth. Runoff i.s sloe. <br />The hazard of water erosion is slight, and the hazard <br />of wind erosion is moderate. This unit is a Loamy <br />Plains range site. Capability unit is IIe-1 Irrigated, <br />IVe-3 Dry land <br />56 KIM-TH£DALUND LOANS, 3 TO 15 PERCENT SLOPES This <br />complex consists of gently sloping to moderately steep <br />soils on uplands, fans, and vallegsides. It is about <br />45 percent Kim loam and about 35 percent Thedalund <br />loam. The Kim loam is less sloping and the Thedalund <br />loam is steeper. Included wi tt+ these soils in mapping <br />are small areas of Renohill and Midway :soils, small <br />rock outcrops and gravel knobs, and some small uet seep <br />spots. The Kim series consists of deep, yell drained <br />soils that formed -in mixed alluvium. Zn a typical soil <br />profile the surface layer is a loamabout 5 inches <br />thi rk. The underlying material is a loam about 55 <br />inches thick. The Thedalund series consists of <br />moderately deep, yell drained soils that formed in <br />material weathered from sandstone and shale. Tn a <br />typical soil profile the surface laver is a loam about <br />4 inches thick. The subsurface layer is a loam about 3 <br />inches thick. The underlying mater i~al is loam about <br />23 inches thick over soft shale and sandstone. <br />Permeaui lity is moderate, ar~d the available +:ater <br />c agar. ity is medium to high. Reaction is neutral to <br />mildly alkaline above a depth of about 4 inches and <br />moderately alkaline below that dept;,. Runoff is ,rapid, <br />end the hazard of eater erosion is severe. This unit is <br />a Loamy Plains range site. Capability unit is VIe-1 <br />102 STONEMAM LOAM, 3 TO 5 PERCENT SLOPES This gently <br />Page 10 <br />
