16C-Patent loam <br />which differ from Patent in being more stratified (with an irregular <br />decrease in organic matter with depth). These inclusions make up <br />about 70 percent of the mapping unit. <br />Permeability of the Patent soil is moderate. Effective rooting depth <br />is 60..inches or more. Available water capacity is high. Surface <br />runoff is slow and the erosion hazard is moderate. <br />On private land this soil is used mainly for crop, hay and pasture land. <br />Alfalfa, small grains, and grass or grass-legume mixtures are grown. <br />On BLM land this soil is used for native range. <br />- Irrigation is by flooding or furrows. Sprinklers are a good alternative <br />method. Ih^op structures in ditches will facilitate water control <br />and prevent excessive ditch erosion. <br />The potential native vegetation on this 'soil is dominated by bluebunch <br />wheatgrass, western wheatgrass, needleandthread, Nevada and.5andberg <br />bluegrass, fleabane, lupine, big sagebrush, and low rabbitbrush. <br />Nhen the range condition deteriorates, forbs and woody shrubs increase. <br />In poor condition, undesirable weeds and annual plants are abundant. <br />Grazing management will maintain and improve ranp,e conditions. This <br />soil is amenable to seeding to dryland grasses. Crested wheatgrass <br />is a good grass for seeding on this soil. Brush management may be <br />. .. ... ._ r-C <br />
