<br />R6-CD <br />layer and the proper use of improved water infiltration, tilth, <br />control soil erosion and help to maintain organic matter content. <br />Land smoothing and management of irrigation water are needed in <br />some areas to obtain a more uniform distribution of irrigation <br />water. <br />z <br />Irrigation methods suitable for this soil are furrow, corrugation, <br />and sprinklers. F4~rrow irrigation is suited for row crops. <br />Sprinklers and corrugations are suited to alfalfa and small grains. <br />Regardless of the irrigation method used, water must be applied <br />at low levels to minimize soil erosion. <br />The primary m,~nagement concerns on dryland areas are controlling <br />soil erosion moisture. Stubble mulching and incorporating crop <br />residues on and into the surface are essential to reduce runoff <br />~- <br />and erosion. This also improves water infiltration into the soil <br />and conserves moisture. The construction of terraces reduces water <br />runoff and conserves soil moisture. Chiseling and sub soiling are <br />effective in breaking up tillage pans and improves water penetration. <br />Tillage operation should be kept to a minimum. <br />It-uigeland vegetation on this soil consists mainly of hig sagebrush, <br />pinyon pine, Rocky Mountain juniper, western wheatgrass, needle- <br />and-thread grass, blue grams, mutton grass, Indian ricegrass, and <br />junegrass. Proper grazing use and planned grazing systems are the <br /> <br />
