NONTECHNICAL SOILS DESCRIP~.uN REPORT weldrge Map ~ Soil none and description Symbol This unit consists of very deep, moderately well drained soils on terraces and mesa summits. These soils formed in alluvium. The surface layer is clay loam about 5 inches thick. The upper part of the subsoil is clay loam about 70 inches thick. The next subsoil layer is gravelly clay loam about B inches thick, atd the lower part of the subsoil is very cobbly clay loam and cobbly clay loam about 21 inches thick. The substratum to a depth below 60 inches is stony clay loam. Permeability of this soil is moderately slow. Available water capacity is high. Effective rooting depth is 60 inches or more. Runoff is medium, and the hazard of water erosion is moderate. A seasonal, irrigation induced, high water table fluctuates between depths of 35 to 50 inches from April through September. This unit is considered prime farmland. Capability Subclass 3E; irrigated; 7C; nonirrigated Capability classification is the grouping of soils to show, in a general way, their suitability for most kinds of farming. It is a practical classification based on limitations of [he soils, the risk of damage when they are used, and the way they respond to treatment. The soils are classified according to degree end kind of permanent limitation, but without consideration of major and generally expensive laMforming that would change the slope, depth, or other characteristics of the soils; without consideration of possible unlikely major reclamation projects. Class III - Severe limitations that reduce choice of crops or require special conservation practices or both. Class VII - Not suited for cultivation. Very severe limitations. Suited for range, woodland or wildlife uses if carefully managed. Usually cannot apply physical practices such as pitting, furrowing, seeding, etc. E -Erosion by wind of water is the major problem.
