E8-CD - BODOT CLAY, 3-10~ SLOPES <br />/'~ CLASS IVe IRRIGATED & NONIRRIGATED <br />This moderately deep, well drained soil is found on gently sloping to sloping <br />shale hills. It formed in residuum from shale. Elevation ranges from 6,000 <br />to 7,000 feet. The average precipitation is 14-17", average annual air <br />temperature is 47-50 degrees F., and the average frost free season is 110- <br />130 days. <br />Typically, the surface layer is gray clay about, fi" thick. The underlying <br />material is gray clay about 27" thick overlying shale at a depth of 33". <br />Depth to shale bedrock is between 20 and 40". <br />Permeability is slow. Effective rooting depth is 20-40" due to the presence <br />of bedrock. Available water capacity is low. Surface runoff is medium <br />and the hazard of water erosion is high. <br />This soil is mainly used for irrigated crops, pasture, hayland and range. <br />The primary management concerns are .controlling erosion by water, maintaining <br />organic matter and fertility in the surface layer, and proper use of irriga- <br />tion water. <br />Native vegetation consists of Indian ricegrass, junegrass, western wheatgrass, <br />blue grama, serviceberry, bitterbrush, big sagebrush, pinyon pine, and Rocky <br />Mountain juniper. <br />The Bodot soil is suited to the production of pinyon and juniper which <br />results in products such as firewood, fence posts, Christmas trees and pinyon <br />nuts. Wildlife such as cottontail rabbit, elk, mule deer, coyotes, squirrels'', <br />and mourning dove utilize this soil type and habitat. <br />Depth to bedrock and high shrink swell are the primary limiting soil features <br />when planning for home construction or other community developments. The <br />foundations of buildings must be designed to compensate for the above factors. <br />13C <br />
