<br />These are deep, poorly drained soils that formed in
<br />recent alluvium. Nu one parlors is typical. Commonly the
<br />soils have a mottled, mildly to mak•ntely alkaline loamy
<br />or clayey :surface layer and underlying material that ex-
<br />tends to a depth of 60 inches or more. In place they have
<br />a stayed layer in the underlying material. '
<br />Moat of the acreage is subject to excessive runoff. The
<br />water table is at or near the surface in spring and during
<br />tltc peak of the irrigation seawn. -
<br />These soils are used for rangeland and wildlife habitat.
<br />Some ama~l areas are irrigated pasture.
<br />The potential native vegetation is dominated by
<br />awitchgrass, prairie cordgrass, saltgrass, alkali sacaton,
<br />big bluestem, indiangrass, western wheatgrasc, slender
<br />wheatgras:s, stvlge, and rush. Cattails and bullrush grow
<br />in the swampy spots associated with these rdnge sites.
<br />Potential production ranges from •1,0110 pounds per acre in
<br />favorable ,years to 3,1100 pounds in unfavorable years. As
<br />range condition deteriorates, the tall and mid grasses
<br />decrease, production drops, and saltgrass, sedge, and rush
<br />increase. 7'he farming and irrigation in adjacent areas has
<br />increased the amount of salts on much of the acreage.
<br />Management of vegetation on this soil should be based
<br />on taking half and leaving half of the total annual produc-
<br />tion. Switchgrass, big bluestem, indiangrdss, western
<br />wheatgrass, pubescent wheatgrasa, intermediate wheat-
<br />grass, tai? wheatgrass, and tall fescue are suitable for
<br />w•r•dinq. 9'he pl:mts selected should met the seasrmal
<br />requirements of livrstm•k. F'or sucrr.+sful seeding, a firm
<br />prepared seedbed is needed. A grdss drill should Ix• usrvl.
<br />Seeding early in spring has proven must suttessful. Til-
<br />lage is needed to eliminate the undesirable vegetation.
<br />Wetland wildlife, especially waterfowl, utilize this unit.
<br />The wetland plants provide nesting and protective cover
<br />as well as some food. The nearby irrigated cropland,
<br />where wildlife obtain much of their Cood and find protec-
<br />tive cover, makes this unit valuable to both wetland and
<br />openland wildlife.
<br />Openland wil<Ilile, especially pheasant, use this unit for
<br />cover and nesting. Deer find excellent cover in some
<br />areas. These valuable wildlife areas should be protected
<br />from fire and fenced to prevent encroachment and
<br />overuse b}' livestock. They should not be drained. Capa-

<br />Typically the xurfae•e layer is brown sanely loam about
<br />10 inches thick. The subsoil is pale brown and yellowish
<br />brown sandy clay loam about 15 inches thick. The sub-
<br />stratum to a depth of fi0 inches is calcareous tint sandy

<br />wheat is the principal crop. The predicted averdge yield is

<br />wheat can be seedwi. Generally precipitation is bro luv
<br />for beneficial use of fertilizer. _
<br />Stubble mulch farming, stripcropping, and minimum tit
<br />gage are needed to control soil blowing and water erosion
<br />Terracing also may be needed to control water erosion.
<br />The potential native vegetation un this range site i
