<br />J <br /> <br /> <br /> <br /> <br />~: <br /> <br /> <br />b) Soil unit 33, Tisworth fine sandy loam, 0-5 percent slopes. <br />This is a well-drained soil formed in alluvium on alluvial fans. The <br />Surface layer is .a sandy loam about 3 inches thick. The subsoil is <br />loam to sandy loam about 13 inches thick. The upper 8 inches of the <br />substratum is a loam, while the lower portion is gravelly loam. This <br />soil is rated as poor for topsoil, due to excessive sodium. The erosion <br />hazard is slight, with a slow runoff. <br />Soils other than those mapped and described, may occur within the soil <br />mapping unit boundaries, as inclusions. Both of these above soils, have <br />a shallow surface layer and are poorly suited as topsoil material for <br />_ reclamation. The average annual precipitation of this site is quite low <br />and will present limitations for vegetation establishment. The precipitation <br />_ averages 12 to 14 inches a year. _ -- _ _. _; ...__. _ ___- <br />Exhibit J - Vegetation Information - _ <br />following is a description of the vegetation present on these two soil units: <br />a) On soil unit S,E, the plant community is a pinion-juniper, grass, <br />_ shrub mixture. The site is predominated by Western Wheat and Indian <br />Rice Grasses. Rat~bitbrush and sage brush are interspersed with the <br />- 'grass. Lheatgrass, and other annuals are quite numerous on the sites. <br />This soil unit ha s• very steep slopes, with rock outcrops occurring <br />Within the unit, and the vegetation is sparsely distributed. <br />b) On soil unit 33, the site is dominated almost exclusively by <br />greasewood and cheatgrass. Numerous anriuals occur in small amounts. <br />This site presently produces very little forage annually. The grease- <br />wood stand is very dense. - <br />~ - - - - <br />-. <br /> <br /> <br />Following are seeding recommendations, for revegetating the disturbed stock <br />pile area primarily, and for limited use on the steep sloped pit area: <br />- 1) Grass Seeding Mixture <br />Broadcasted Rate lbs. <br />-- Species Variety Pure Live Seed/Ac. <br />Streambank wheatgrass Sodar <br />Indian ricegrass Paloma <br />Russian wild rye Vinall <br />Total <br />7.0 - <br />8.0 <br />6.0 <br />21.0 lbs.
