<br />from S00 pounds per acre in favorable years to 5011
<br />pounds in unfavorable years. As range condition deteri-
<br />orates, Lhe mid grasses decrease and fm•age production
<br />drops. Undesirablo weeds and annuals invade the site as
<br />range condition becomes pourer.
<br />Management of vegetation on the Shingle soil should be
<br />based on taking half anti leaving half of the total annual
<br />production. Seeding is desirable if the range is in poor
<br />condition. 1Vestern wheatgrass, blue grama, alkali sacaton,
<br />sideoats grama, little bluestem, pubescent whcatgrass,
<br />and crested wheatgrass are suitable Cor 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 sail is
<br />dominated by western whcatgrass and blue grama. Buf-
<br />falograss is also presented. Potential producliun~ranges
<br />from 1,000 pounds per acre in favorable years to G00
<br />pounds in unfavorable years. As range condition deteri-
<br />orates, ablue 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, 61ue grama, sideoats grama, buffalograss, pu-
<br />bescent wheatgrass, anti 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 />frm sorghum stubble, or it can be drilled into a firm
<br />prepared seedbed. Seeding early in spring has proven
<br />most successful. ,
<br />Rangeland wiltllifc, 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 IivesLock and wildlife share the range. Livestock water-
<br />ing facilities also are utilized by various wildlife species.

<br />gle soil in Shaly Plains range site, Renohill soil in Clayey
<br />Plains range site.
<br />fit-Tassel fine sandv loam.- 5 to 20 percent slopes.
<br />This is a shallow, well drained soil on upland breaks at
<br />elevations of 4,850 to 5,200 feet. IL formed in residuum
<br />from sandstone. Included in mapping are small areas of
<br />sandstone outcrop and areas of noncalcareous soils.
<br />Typically the surf:u•e layer of this Tassel soil is light
<br />yellowish brown (inc samly loam about 7 inches thick. The
<br />underlying matrrial in light yellowish brown very fine
<br />sandy loam. Sandstone is at a Depth of about 11 inches.
<br />Permeability is moderately rapid. Available water
<br />capacity is low. The effective rooting depth is 10 to 211
<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, IhreadleaC
<br />sedge, sand reetigrass, and needleandthread. Potential
<br />JHVI:Y ~~
<br />production ranges from 1,750 pounds per acre in favnra-
<br />hle years to 950 pounds in unfavnrxblc years. As range
<br />condition deteriorates, the sideoats grama, little bluestem.
<br />and sand reedgrass decrease; yucca, sedge, and blue
<br />grama incmase; 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 Lhis treeless soil is low,
<br />especially during drought, when annual production can be
<br />xs low as 900 pounds per acre. Rangeland wildlife, such as
<br />antelope and scaled quail, can be attracted by managing
<br />livestock grazing, installing IivesLock watering facilities,
<br />and reseeding where needed.
<br />This soil has poor potential for Vrban development. The
<br />chief limiting feature is Lhe shallow depth to sandstone.
<br />Capability subclass VIe irrigated, Vfe nonirrigated; Sand-
<br />~ne Breaks range site.
<br />62-Terry fine sandy loom, 0 l0 3 percent slopes, This
<br />is a moderately deep, well drained soil on plains at eleva-
<br />tions of 4,500 to 5,000 feel. It formed in residuum from
<br />sandstone. Included in mapping are small areas of soils
<br />that have sanrlslone 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 tine sandy loam about 6 inches thick. The subsoil is
<br />pale brown foe sandy loam about 21 inches thick, The
<br />substratum is very pale brown fine 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 />40 inches. Surface runoff is slow, and the erosion hazard
<br />is low.
<br />This soil is suited to most of the irrigated 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 can be used in irrigating row
<br />crops. Flooding from 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 />ley applications of 6arnyartl manure antl commercial fertil-
<br />izer. Keeping tillage to a minimum and utilizing crop
<br />residue arc im port;tnl.
<br />In nunirrig:drd arc:~s Lhis soil is suited Lo winter wheat,
<br />barley, xnd sory;hum. Most of Lhe acreage is planted Lo
<br />winter wheal. The predicted average yield is 'LS bushels
<br />per acre. The soil is summer fallowed in alternate years
<br />to allow moisture accumulation. Generally precipitation is
<br />ton tow for beneficial use oC fertilizer.
<br />Stubble mulch farming, stripcropping, and minimum til-
<br />lage are needed to control soil blowing and water erosion.
