"• <br /> <br />If the range condition deteriorates, less preferred forage plants <br />increase. In poor condition, undesirable plants are domimnt. Therefore, <br />grazing should be ma~ged so that the desired balance of species is <br />maintained in the plant community. <br />If the range vegetation is }seriously deteriorated, seeding is Waded. <br />For successful,seedings, a seedbed should be prepared and the seeds drilled. <br />The main limitation for seeding is slopes greater than 15 percent which may <br />be broadcase seeded. Suitable seeding mixtures can include western <br />wheatgrass, bluebunch wheatgrass,. and crested wheatgrass. There may be some <br />difficulty in obtaining seed for some or all of these species. Sudcessful <br />seedings can be expected only in years of above normal precipitation. <br />Seeding late in fall helps to insure that the content of moisture in the . <br />soil will be adequate for the establishment of seedlings mre spring. The <br />plants selected for seeding should meet the seasonal requirements of <br />livestock or wildlife, or both. <br />The Abor soil is the nonirrigated suited to the hazard of water erosion <br />and clayey tenure crops. <br />Erosion can be minimized on this unit by using it as rangeland or by <br />seeding it in grass. Because of the clay texture, tillage operations must <br />be performed when the soil is et the pt+oper moisture content. A tillage pan. <br />forms easily if ~, ~ y Spy ` 1 S tilled when wet. Chiseling or <br />subsoiling breaks up the tillage pan. <br />If this unit is used for homesite development, the main limitations are <br />slope, depth to bedrock, very slow permeability, shrink-swell potential, and <br />low strength. Due to the high amount of expandable clays in tha Abor soil, <br />special designs may not offset all of the Iimitetions. <br />
