<br />"~ <br />SOIL DESCRIPTIONS <br />JAKE KAUFFMAN & SON INC. RECLAMATION PLAN <br />33 - Fiuvaguents, nearly level <br />Vw-1 Dryland <br />This soil is on flood plains, low terraces, and bottom lands. The <br />surface and underlying layers are extremely variable, ranging from <br />sandy loam to clay loam, and are commonly stratified with thin Layers <br />of sand ar clay. In places the underlying material is sand and <br />gravel. A water table is commonly at a depth of less than 12 inches <br />at some time during the spring and summer, and the soil can be <br />occasionally flooded during the spring and summer. Drainage is often <br />impractical or impossible because of a lac4: of suitable outlets. <br />Runoff is slight, and the hazard of erosion is slight. <br />These soils are suited to pasture or native grasses. <br />This unit is a Wet Meadow range site <br />60 - Larim gravelly sandy loam, 5 to 40 percent slopes VIe-4 Dryland <br />This strongly sloping to steep soil is on fans, benches, and terrace <br />edges. The Larim series consists of deep, well drained soils that <br />formed in mixed alluvium. These soils are underlain by very gravelly <br />sand at a depth of about 11 to 20 inches. The native vegetation is <br />mainly blue grama, needlegrass, sideoats grama, snakeweed, and some <br />fortis and shrubs. Mean annual precipitation ranges from 13 to 15 <br />inches, mean annual air temperature ranges from 48 to 50 degrees F, <br />and frost-free period ranges from 135 to 150 days. <br />In a typical soil profile, the surface layer is grayish brown gravelly <br />sandy loam about 4 inches thick. The subsoil is brown gravelly sandy <br />clay loam about 5 inches thick and pale brown very gravelly sandy loam <br />about 6 inches thick. The underlying material is light Yellowish <br />brown very gravelly loamy sand. Included with this soil in mapping <br />are small areas of soil that have a surface layer and subsoil of <br />gravelly loamy sand. Also included are small areas of soil in which <br />shale or sandstone is at a depth of 10 to 20 inches. <br />Permeability is moderate above a depth of about 15 inches and very <br />rapid below that depth. The available water holding capacity is low <br />or medium. Reaction is neutral to mildly alkaline. Runoff is medium <br />to rapid , and the hazard of erosion is severe. <br />This soil is suited to pasture and native grasses. <br />This unit is a Gravelly Foothill range site. <br />(1) <br />
