weldrge <br />I Map ~ Soil name end description <br />symbol <br />C - Climate is the mej or hazard. Growing season may be <br />very short; there is a shortage of rainfall or both. <br />Rp ~ Persayo silty clay loam, 12 to 40 percent slopes <br />This unit is poorly suited for row crops due to slope. <br />This unit is best suited to a permanent cover crop. <br />Because of the slope, sprinkler or drip irrigation is <br />most suitable for the less sloping areas. Irrigation <br />water needs to be applied at a rate that insures <br />optimum production without increasing deep percolation, <br />runoff, and erosion. <br />This unit consists chiefly of exposed Mancos shale with <br />areas of thin silty clay loam soils over Mancos shale. <br />Commonly pebbles and cobbles, as collwium or slope <br />wash, from adjoining terrace remnants are strewn on the <br />surface. The surface layer is silty clay 4 inches <br />thick. The upper 7 inches of the underlying material <br />are silty clay, and the lower part to a depth of 79 <br />inches is silty clay. Gypsum crystals are common just <br />above the fractured underlying shale. Permeability of <br />this sot( material is slow. Avai table water capacity <br />is very low. Runoff is rapid, and hazard of water <br />erosion is high. <br />Capability Subclass 7C; nonirrigated <br />Capability classification is the grouping of soils to <br />show, in a general way, their suitability for most <br />kinds of farming. It is a practical classification <br />based on limitations of the soils, the risk of damage <br />when they are used, end the way they resporxl to <br />treatment. The soils are classified according to <br />degree and kind of permanent limitation, but without <br />consideration of major end generally expensive <br />landforming that would change the slope, depth, or <br />other cheracterist ics of the soils; without <br />consideration of possible unlikely major reclamation <br />projects. <br />
