u <br /> <br />If [he range is overgrazed, the proportion of preferred forage plants <br />., <br />~~ <br />decreases and the proportion of less preferred forage plants increases. <br />Therefore, livestock grazing should be managed so that the desired balance of <br />preferred species is maintained in the plant community. Deferred grazing, <br />rotating grazing, and alternating the season of grazing are suitable <br />management practices. <br />Range seeding is suitable if the range is in poor condition. This unit <br /> <br /> <br /> <br />responds well to fertilizer, to range seeding, and to proper grazing use. <br />The main limitations for seeding are droughtiness and the hazard of erosion. <br />Seeding should be done in the stubble left from a preceeding crop. This <br />preserves the ground cover and helps to hold snow, which provides additional <br />moleture. This unit is limited for livestock waterlog ponds and other water <br />impoundments because of the seepage potential. <br />This unit is suited to nonirrigated crops. If this unit is used for <br />nonirrigated crops, the main ]Smltstluns are droughtiness and the hazard of <br />erosion. <br />Because precipitation is not sufficient for annual cropping, a cropping <br />system that includes small grain and summer fallow is most suitable. Crops <br />that are tolerant of drought are beat suited because the available moisture <br />is not adequate for good growth of most other plants. Maintaining crop <br />residue on or near the surface reduces runoff, reduces soil blowing, and <br />helps to maintain soil til[h and organic matter content. Tillage should be <br />kept to a minimum. Soil blowing can be reduced by planting crops in <br />alternate strips a[ right angles to the prevailing wind. <br />
