<br />Map unit: Ra <br /> <br />Turley clay loam, 0 to 2 percent slopes <br /> <br />Description Category: AGR <br /> <br />Agronomic <br /> <br />This unit is suited for inigated crops. It has few limitations. Furrow and sprinkler <br />inigation is suited to this soil. Irrigation water needs to be applied at a rate that insures <br />optimum production without increasing deep percolation, runoff, and erasio <br />n, Use of pipe or ditch lining reduces water loss and deep percolation. Tilth and fertility <br />can be improved by retuming crop residue to the soil and using a suitable rotation. <br />Excessive cultivation can result in the formation of a tillage pan. This pa <br />n can be broken by subsoiling when the soil is dry, <br /> <br />Description Category: xes Capability Subclass <br /> <br />Capability Subclass 2E; irrigated; 7C; nonirrigated <br /> <br />Description Category: ZCS Class Legend <br /> <br />Capability dassification is the grouping of soils to show, in a general way. their <br />suitability for most kinds of fanning. It Is a practical classiflcation 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 land fanning 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 II . Some limitations that reduce the choice of crops or require moderate <br />conservation measures. <br />Class VII . Not suited for cultivation. Very severe limitations. Suited for range, <br />woodland or wildlife uses if carefully managed, Usually cannot apply physical practices <br />such as pitting, furrowing, seeding, etc. <br />E - Erosion by wind of water is the major problem, <br />C . Climate is the major hazard. Growing season may be very short; there is a shortage <br />of rainfall or both, <br />Description Category: TPF Prime Farmland <br /> <br />This unit is considered prime farmland. <br /> <br />Description Category: SOl Soil <br /> <br />This unit consists of very deep, well drained soils on alluvial fans and terraces. These <br />soils fanned in mixed alluvlum derived from sedimentary rock sources. The surlace <br />iayer is day loam aboul18 inches thick. The upper 29 inches of the unde~ying ma <br />terial are clay loam with strata of loamy sand. Below this to a depth of more than 60 <br />inches is sandy loam and sandy clay loam. Permeability of this soil is moderately slow. <br />Available water capacity is high. Effective rooting depth is 60 inches or more <br />. Runoff is slow, and the hazard of water erosion is slight. Piping is a hazard, <br /> <br />Thurslu.y, Muy 25, 2000 <br /> <br />Puge 6 of9 <br />
