L? ? V <br />r ., <br />In nonirrigated Wrens this gull is suited to winter wheat, barley and <br />sorghum. Most of the area is devoted to winter wheat which is alter- <br />hated with summer fallow to allow moisture accumulation. Normnlly, <br />precipitation is too low to make beneficial use of fertilizers, <br /> <br />(tow <br />Good cultural practices such as stubble mulch farming, strip cropping <br />and minimum tillage are needed to combat wind and water erosion.' <br />Terracing may also be needed to control water erosion. <br />The potential native vegetation on this soil is dominated by blue grams. <br />Several midgrasses such as western wheatgrass and needle and thread are <br />also present. Potential production ranges from 1600 pounds per acre in <br />favorable years to 1000 pounds per acre in unfavorable years. when range <br />condition deteriorates, the midgrasses decrease, blue grams, buffalograss, <br />snakeweed, yucca and fringed sage increase and production drops. Undesir- <br />able weeds and annuals invade the site as range condition becomes poorer. <br />Management of vegetation on this soil should be based on taking lialf <br />and leaving half of the total annual production. Seeding is advisable if <br />range is in poor condition. Sideoats grama, little bluestem, western <br />wheatgrass, blue grams, pubescent wheatgrass and crested wheatgrass are <br />suitable for seeding. The grass selected sho+?ld meet the seasonal <br />requirements of livestock. For successful seeding, a clean, firm, sorg- <br />hum stubble -- prepared the growing season prior to seeding -- or a <br />firm, prepared seedbed and grass drill should be used. Early spring <br />seeding has proven most successful... ? <br />Windbreaks and environmental plantings are generally well suited on <br />this soul. Generally all trees and shrubs adapted to this area will <br />grow. Continued cultivation to control competing vegetation should be
