<br />quolls ere poory drelned sells on good plains et eleve-
<br />tans of 7,500 to 8,500 feet. They farmed In alluvium and

<br />to 20 inches, me average annual air temperature is
<br />about 37 to 43 degrees F, end the frosbfree season is
<br />30 to SO days. Some are only 2 to 41ee[ deep over sand
<br />end gravel. The profile renges from sandy loam to clay
<br />end is communty stratified.
<br />The surface layer is dark coloretl and Is 20 or more
<br />inches thick. The water table is within 10 to 24 inches of
<br />the surface dunng the growing season.
<br />Surface runoff is slow. The erosion hazard is elighL
<br />Shallow, brief flooding occurs during apdng runoff.
<br />Inclutled in mapping ere smell areas m soils that have
<br />peat at the surface. SoIIa the[ do not have a thick, tlark
<br />colored surtace layer are also included.
<br />Much of the acreage Is imgated antl used for hay (fig.
<br />e). Part of tl Is used for wildlge. The coltl climate end
<br />short growing season Ilma the production of lntrotluced
<br />grasses and preclude the use of this sell es eroplantl.
<br />Management of Imgetion water, subwrfece tlralnege,
<br />end fertll'aetion ere nestled to maintain grass hey pro-

<br />smooth brome, Gamson creeping }oxtail, end tlmoNy.
<br />The total annual producton avereges about 2,500
<br />pounds of air-dry forage per acre.
<br />Irrigation systems must be tlaslgnetl to avoid ovennt
<br />getlon, pondinp, end erosion, and to return excess water
<br />to the streams. Ponded imgation water decreases hay
<br />production.
<br />Spring ferglization is auggestetl. Fell applications of
<br />fertilizer may be partly lost dunng the spring snowmelt
<br />Large quantiges m nitrogen, 40 to 100 pounds per acre,
<br />and phosphorous, 15 to 30 pounds per acre, are nestled
<br />for most irrigated haylantl.
<br />Fencing is needed if this unit is grazed.
<br />Rangeland vegetation is dominantty tuged halrgrass,
<br />slender wheetgraes, sedges, end rushes. Tha average
<br />annual production is about 2,500 pounds. As range con-
<br />dkion declines, shrubs end (orbs become abundam,
<br />along with Introduced greases, such as timothy, smooth
<br />brome, redtop, Kentucky bluegrass, and orchardgress,
<br />which era not native to Me Brea.
<br />If plants become rootbound, producgon decreases.
<br />Ripping or breaking up the tlense root growth when the
<br />water table is low restores plant vigor. If low protluctlon
<br />is caused by a lack of plant cover, seeding is nestled.
<br />Suitable for Beetling are slentler wheatgress. smooth

<br />ing }oxtail. Tha seed should be drilled into a fine
<br />seedbed.
<br />Wetlantl wiltllae, such as mallard, teal, and various
<br />shore birtls, are ettrected to this unit, which is rypitelly

<br />Other wildlge are beaver, mink, entl muakreL The num-
<br />bers can be further increased if shallow water tlevelop-
<br />ments are constructed and the natural plant cover is
<br />allowed to develop. Tha wetlands can bs improved by
<br />managing livestock grazing, fencing to control livestock,
<br />preventing fires, and preventing drainage. This unit Is
<br />also valuable as big game winter range.
<br />Seasonal flooding end depth to the water table are the
<br />most limiting lectures to be considered in the design of
<br />access roatls and community tlevelopment. An onsite
<br />investlgation is necessary before planning any construe-
<br />tbn because of the wide venation of soil propeNea.
<br />Adequate soil drainage is needetl for most land uses.
<br />The eapabiliry subclass Is Vlw, end the range site Is

<br />The average annual precipitation is about ib to 18
<br />inches, the average annual air temperature is about 37
<br />to 42 degrees F, and the frost-free season is about 35 to
<br />75 days.
<br />Small areas of Clmenon loam, Cebone loam, end
<br />Weybe clay loam are included in mapping.
<br />Typically the sudaca layer of the Mayoworth soil is
<br />tlark greyish brown Clay loam about 10 inches thick. The
<br />subsoil is light yellowish brown clay about 14 inches
<br />thick. The substratum Is light yellowish brown clay about
<br />4 Inches thick Shale bedrock is at a tlapth of about 28
<br />inches.
<br />Penneebiliry Is slow. The etteClNe roogng depth is ZO
<br />to 40 Inches. The available water capacity is low. Sur-
<br />face runoff is rapid, and the erosion hazard is high.
<br />Most of the acreage is rengelantl. Part of h is used for
<br />recreation and wildlife. Tne cold climate and short grow-
<br />ing season Ilmit the production of introduced grasses
<br />and preclude the use of this soil as croplantl.
<br />Western wheatgreas, letterman needlegress, mutton-
<br />grass, and big sagebrush dominate the rangeland vege•
<br />tation. Shrubs become dominant over en extremely
<br />sparse stand of grass u range condition declines.
<br />Grazing management is essential for the melntenance
<br />of this site. Brush confrol Is nestled to improve range
<br />contlition If there ere still remnants of native grass. The
<br />sfte Is too steep to be seeded whh a drill.
<br />This soil provides spring and fall transition range for
<br />mule tleer end elk Other wiltllge include sage grouse,
<br />jackrabbit, cogontail, end coyote. Managing INestock
<br />grazing end contralling sagebmsh are necessary to pro-
<br />tect big game range and sage grouse habitat.
<br />Depth to rack, the shrink-swell potential, end the slope

<br />apmenL Cut end gll slopes should be avoided to prevent
<br />hillside slippage. Road design should provide drainage
<br />outlets for surtace runoff.
