<br />Map unit: BcS Sagers silty clay loam, Saline, 0 to 2 percent slopes <br /> <br />Description Category: AGR <br /> <br />Agronomic <br /> <br />This unit is poorty suited far irrigated crops, The main limitation is salinity, Most areas <br />will need extensive reclamation before crops can be grown. A combination of leaching <br />and drainage will be required for reclamation. Salinity can be reduced by I <br />eaching salts from the soil using irrigation water that is low in content of salts. Tile <br />drainage can be used to lower the water table if a suitable outlet is available. Intensive <br />management Is required to reduce the salinity and maintain soil productivi <br />ty. <br /> <br />Description Category: XCS Capability Subclass <br /> <br />Capability Subclass 8S; nonirrigated <br /> <br />Description Category: ZCS Class Legend <br /> <br />Capability classification is the grouping of soils to show, in a general way, their <br />suitability for most kinds of farming. It is a practical classification based on limitations of <br />the soils, the risk of damage when they are used. and the way they respond <br />to treatment. The soils are classified aCCOrding to degree and kind of permanent <br />limitation, but without consideration of major and generally expensive landfonning that <br />would change the slope, depth, or other characteristics of the soils; without consider <br />ation of possible unlikely major reclamation projects. <br />Class ViII - Not suited for cuitivation, range, pasture or woodland. Suited only for <br />reaeation, wildlife, water supply or esthetic purposes. <br />S - Major problem is in the soil. it may be too shallow, too heavy. stony, low in fertiiity, <br />salty, alkaline or have low moisture capacity, <br />D@scription Category: SOl Soil <br /> <br />This unit consists of very deep. well drained soils on old alluvial fans and low terraces. <br />These soils formed in alluvium derived dominantly from Mancos shale. The surface <br />layer is silly clay loam 12 Inches thick. The upper 13 inches of the underlying m <br />alerial are silty clay loam, and the lower part to a depth of more than 60 inches is silty <br />day loam with few fine gypsum crystals, Penneabillty of this soil is slow, Available <br />water capacity is moderate. Effective rooting depth Is 60 inches or more. R <br />unoff is slow, and the hazard of water erosion is slight. Salts moderately to severely <br />affect plant adaptation. growth, and water availability. Salts are also severely corrosive <br />to concrete and untreated steel pipe, <br /> <br />Thursday, May 25, 2000 <br /> <br />Pagelof9 <br />
