<br />from 800 pounds per acre in favorable years to 500
<br />pounds in unfavorable years. As range condition deteri-
<br />orates, the mid grasses decrease and forage production
<br />drops. Undesirable weeds and annu:ds invade the site as
<br />range condition becomes poorer.
<br />Management of vegetation on the Shingle soil should be
<br />based on taking half and leaving half of the total annual
<br />production. Seeding is desirable if the range is in poor
<br />condition. Western a•heatgrass, blue grama, alkali sacaton,
<br />sideoats grama, little bluestem, pubescent wheatgrass,
<br />and crested wheatgrass are suitable for seeding. The
<br />grass selected should meet the seasonal requirements of
<br />livestock. It can be seeded into a clean, firm sorghum
<br />stubble, or it can be drilled into a firm prepared seedbed.
<br />Seeding early in spring has proven most successful.
<br />The potential native vegetation on the Renohill soil is
<br />dominated by western wheatgrass and blue grama. Buf-
<br />falograss is also presented. Potential production ranges
<br />from 1,000 pounds per acre in favorable years to 600
<br />pounds in unfavorable years. As range condition deteri-
<br />orates, a 61ue grama-buffalograss sod forms. Undesirable
<br />weeds and annuals invade the site as range condition
<br />becomes poorer.
<br />Management of vegetation on the Renohill soil should
<br />be based on taking half and leaving half of the total an-
<br />nual production. Range pitting can reduce runoff. Seeding
<br />is desirable if the range is in poor condition. Western
<br />wheatgrass, blue grama, sideoats grama, buffalograss, pu-
<br />bescent wheatgrass, and crested wheatgrass are suitable
<br />for seeding. The grass selected should meet the seasonal
<br />requirements of livestock. IC can be seeded into a clean,
<br />firm sorghum stubble, or it can be drilled into a frm
<br />prepared seedbed. Seeding early in spring has proven
<br />most successful. ,
<br />Rangeland wildlife, such as antelope, cottontail, and
<br />coyote, are best suited to this unit. Because forage
<br />production is typically low, grazing management is needed
<br />if livestock and wildlife share the range, Livestock water-
<br />ing facilities also are utilized by various wildlife species.
<br />Capability subclass Vle irrigated, Vle nonirrigated; Shin-
<br />gle soil in Shaly Plains range site, Renohill soil in Clayey
<br />Plains range site.
<br />61-Tassel fine sandyham. 5 to 20 percent sloces.
<br />This is a shallow, well drained soil on upland breaks at
<br />elevations of 4,850 Lo 5,200 feet. It formed in residuum
<br />from sandstone. Included in mapping are small areas of
<br />sandstone outcrop and areas of noncalcareous soils.
<br />9'ypirally the surface layer of this Tassel soil is light
<br />yellowish brown fine sandy loam about 7 inches thick. The
<br />underlying material is light yellowish brown very foe
<br />sandy loam. SandsWne is at a depth of about 11 inches.
<br />Permeability is moderately rapid. Available water
<br />capacity is low. The effective rooting depth is ]0 to 20
<br />inches. Surface runoff is medium, and the erosion hazard
<br />is moderate.
<br />The potential native vegetation is dominated by
<br />sideoats grama, little bluestem, blue grama, threadleaf
<br />sedge, sand reedgrass, and needleandthread. Potential
<br />production ranges from 1,750 pounds per acre in favora-
<br />ble years to 950 pounds in unfavorable years. As range
<br />condition deteriorates, the sideoats grama, little bluestem,
<br />and sand reedgrass decrease; yucca, sedge, and. blue
<br />grama increase; and forage production drops.
<br />Management of vegetation should be based on taking
<br />half or less of the total annual production. Deferred graz-
<br />ing is practical in improving range condition. Seeding and
<br />mechanical treatment are impractical.
<br />Windbreaks and environmental plantings are generally
<br />not suited to this soil. Onsite investigation is needed to
<br />determine if plantings are feasible.
<br />Production of vegetation on this treeless soil is low,
<br />especially during drought, when annual production can be
<br />as low as 300 pounds per acre. Rangeland wildlife, such as
<br />antelope and scaled quail, can be attracted by managing
<br />livestock grazing, installing livestock watering facilities,
<br />and reseeding where needed.
<br />This soil has poor potential for urban development. The
<br />chief limiting feature is the shallow depth to sandstone.
<br />Capability subclass VIe irrigated, Vle nonirrigated; Sand-
<br />~ne Breaks range site. '
<br />62-Terry fine sandy loam, 0 to 3 percent slopes. This
<br />is a moderately deep, well drained soil on plains at eleva-
<br />tions oC 4,500 to 5,000 feet. IL formed in residuum from
<br />sandstone. Included in mapping are small areas of soils
<br />that have sandstone deeper than 40 inches. Also included
<br />are small areas of soils that have a subsoil of sandy clay
<br />loam and clay loam.
<br />Typically the surface layer of this Terry soil is pale
<br />brown fine sandy loam about 6 inches thick. The subsoil is
<br />pale brown fine sandy loam about 21 inches thick. The
<br />substratum is very pale brown foe sandy loam. Sand-
<br />stone is at a depth of about 37 inches.
<br />Permeability is moderately rapid. Available water
<br />capacity is moderate. The effective rooting depth is 20 to
<br />90 inches. Surface runoff is slow, and the erosion hazard
<br />is low.
<br />This soil is suited to most of the imgated crops com-
<br />monly grown in the area. The moderate depth restricts
<br />some crops. A suitable cropping system is corn, corn for
<br />silage, barley, 3 to 4 years of alfalfa, and wheat. This soil
<br />is also well suited to irrigated pasture.
<br />Furrows or sprinklers ran be used in irrigating row
<br />crops. Flooding Crom contour ditches and sprinkling are
<br />suitable in irrigating close grown crops and pasture. Small
<br />heads of water and short runs reduce the risk of erosion.
<br />Production can be maintained by frequent irrigations and
<br />by applications of barnyarvi manure and commercial fertil-
<br />izer. Keeping tillage to a minimum and utilizing crop
<br />rrsidur am im poriant.
<br />In nunirrigated areas Lhis soil is suited to winter wheat,
<br />barley, anti sorghum. Most of the acreage is planted Lo
<br />winter wheal. The predicted average yield is 25 bushels
<br />per acre. The soil is summer followed in alternate years
<br />to allow moisture accumulation. Generally precipitation is
<br />too low for beneficial use of fertilizer.
<br />Stubble mulch farming, striperopping, and minimum til-
<br />lage are needed to control soil blowing and water erosion.
