Closely spaced contour ditches or sprinklers can be used in irrigating close grown crops. <br />Contour furrows or sprinklers should be used for new crops. Applications of nitrogen and <br />phosphorus help in maintaining good production. <br />The potential native vegetation on this range site is dominated by sand bluestem, sand <br />reedgrass, and blue grams. Needleand[hread, swithgrass, sideoats grams, and western <br />wheatgrass are also prominent. Potential production ranges from 2200 pounds per acre in <br />favorable years to 1800 pounds in unfavorable years. As range condition deteriorates, the <br />sand bluestem, sand reedgrass, and switchgrass decrease and blue grams, sand dropseed, <br />and sand sage increase. Annual weeds and greases invade the site as range condition <br />becomes poorer. <br />Management of vegetation on this soil should be based on taking half and leaving half of <br />the total annual production. Seeding is desirable if the range is in poor condition. Sand <br />bluestem, sand reedgrass, switchgrass, sideoats grams, blue grams, pubescent wheatgrass, <br />and crested wheatgrass are suitable for seeding. The grass selected should meet the <br />seasonal ~ requirements of livestock. It can be seeded into a clean, firm sorghum stubble, <br />or it can be drilled into a firm prepared seedbed. Seeding early in spring has proven most <br />successful. <br />Windbreaks and environmental plantings are generally not suited to this soil. Onsite <br />investigation is needed to determine ifplantings aze feasible. <br />Wildlife is an important secondazy use of this soil. The cropland azeas provide favorable <br />habitat for ring-necked pheasant and mourning dove. Many nongame species can be <br />attracted by establishing areas for nesting and escape cover. For pheasants, undisturbed <br />nesting cover is essential and should be included in plans for habitat development, <br />especially, in areas of intensive agriculture. Rangeland wildlife, for example, the pronghorn <br />antelope, can be attracted by developing livestock watering facilities, managing livestock <br />grazing, and reseeding where needed. <br />The underlying sandstone is the most limiting feature of this soil. Neither septic tank <br />absorption fields nor sewage lagoons function properly. Site preparation for dwellings is <br />costly. Environmental and beautification plantings of trees and shrubs can be difficult to <br />establish. Potential is good, however, for such recreational development as camp and picnic <br />areas. Capability subclass IVe imgated, VIe nonirrigated; Sandy Plains range site. <br />75 -Vona Sandy Loam, 0-1 % slopes <br />This is a deep, well drained soil on high terraces at elevations of 4650 to 4950 feet. It <br />formed in alluvial deposits. Included in mapping are some leveled areas and small areas of <br />soils that have a loamy substratum. <br />DMG !!2 Permit <br />Page 48 of 81 <br />
