<br />This unit is cell suited to irrigated hay and pasture. Irrigation water ~~ <br />can be applied by corrugations and by flooding frvn contour ditches. If <br />~~~rttigat ion syraem~ arc used, mm~ should tM cxi *f~ cnntrnir or across rl+~ <br />slope. Water stx~uld W aYpl.ie~J u~ suffi~ieent .anuunts ru wet tl[: rwr. ~~nu <br />but in amounts small enough to minimize leaching of plant nutrients. <br />Leveling helps to insure the unifoan appl.icatiCn of water. Use of nitrogen <br />and phosphorus fertilizer promotes good growth of forage plants. Proper <br />stocking rates, pasture rotation, and restricted grazing during wet periods <br />help to keep the pasture in goad condition and to protect the soil from <br />erosion. If properly managed, .this unit can produce 4 tons of irrigated <br />grass hay per acre. <br />The potential plant camnun.ity .is mainly western wheatgrass, blue grams, <br /> and prairie junegrass. Other less numerous plants axe native bluegrass, <br /> green needlegrass, and little tiluestem. 'Ilia average annual production of _ ' <br />airLdxy vegetation is about 1,300 pounds per acre. If the condition of the <br />range deteriorates, sleepygrass, ring muhly, cholla, and tall rabbitbrush <br />increase. Range seeding is suitable if tt~e range is .in poor oondition. <br /> <br />
