<br />3-Aquolls and Aquents, gravelly substratum. This
<br />nearly level map unit is on bottom lands and (load plains
<br />of all the major streams in the survey area. Aquolls,
<br />which have a dark colored surface layer, make up about
<br />GO percent of the uni vents, which have a lighter
<br />colored surface layer, ma a up about 35 percent. About ~i
<br />percent is Aquepts and Bankard sandy loam.
<br />These arc deep, poorly drained soils that formed in
<br />recent •alluvium. No one pedon is typical. Commonly the
<br />soils have a mottled, mildly alkaline to moderately al-
<br />kaline loamy or clayey surface layer and underlying
<br />material and are underlain by sand or sand and gravel
<br />within 48 inches. In places they have a gleyed layer in the
<br />underlying material.
<br />Most oC the acreage is subject to flooding. The water
<br />table is at or near the surface early in spring and recedes
<br />to as deep as 48 inches late in fall in some years.
<br />These soilsrre used for rangeland and wildlife habitat.
<br />Some small areas have been reclaimed by major drainage
<br />and leveling and are used for irrigated crops.
<br />The potential native vegetation is dominated by alkali
<br />sacaton, switchgnss, and western wheatgrass. Saltgrass,
<br />sedge, rush, and alkali bluegrass are also prominent.
<br />Potential production ranges from 3,000 pounds per acre in
<br />favorable years to 2,000 pounds in unfavorable years. As
<br />range condition deteriotates, the awitchgnss, alkali
<br />sacaton, and western wheatgnss decrease and saltgrass,
<br />sedge, and rush increase.
<br />Management of vegetation should be based on taking
<br />half and leaving half of the total annual production. Seed-
<br />ing is difficult and costly because numerous tillage prac-
<br />tices are required to eliminate the saltgnss sod.
<br />Switchgrass, western wheatgnss, alkali sacaton, tall
<br />wheatgnss, and tall fescue are suitable for seeding. They
<br />can be seeded into a clean, fumt seedbed. Seedbed
<br />preparation usually requires more than 1 year to
<br />eliminate the saltgrass sod. A grasv drill should be used.
<br />Seeding eazly in spring has proven most successful.
<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 imgated cropland,
<br />where wildlife obtain much of their food and find protec-
<br />tive cover, makes this unit valuable to both wetland and
<br />openland wildlife.
<br />Openland wildlife, especially pheasant, use this unit for
<br />cover and nesting. Deer find excellent cover in some
<br />areas.
<br />These valuable wildlife areas should be protected from
<br />fire and fenced to prevent encroachment and overuse by
<br />livestock. They should not be drained.
<br />These soils have good potential as a source of sand and
<br />gravel. Capability subclass Vlw; Salt Meadow Hoge site.
<br />J-Aquolls and Aquepts, flooded. This nearly level
<br />map unit is in depressions in smooth plains and along the
<br />bottoms of natural dninageways throughout the survey
<br />area. Aquolls, which have a dark colored surface layer,
<br />make up about 55 percent oC the unit. Aquepts, which
<br />have a lighter colored surface layer, make up about 25
<br />percent. About 20 percent is soils that are well drained
<br />and soils that have sandstone or shale within 48 inches of
<br />the surface.
