Soil Classification #4: Aquolls and Aquepts, flooded
4---Aquolls and Aquepts, flooded. This nearly level
map unit is in depressions in smooth plains and along the
bottoms of natural drainageways throughout the survey
area. Aquolls, which have a dark colored surface layer.
make up about 55 percent of the unit. Aquepts, which
have a lighter colored surface layer, make up about 2.
percent. About 20 percent is soils that are well drained
and soils that have sandstone or shale within 4$ inches of
the surface.
These are deep, poorly drained soils that formed in
recent alluvium. No one pedon is typical. Commonly the
soils have a mottled, mildly to moderately alkaline loamy
or clayey surface layer and underlying material that ex-
tends to a depth of 60 inches or more. In places they have
a gleyed layer in the underlying material.
Most of the acreage is subject to excessive runoff. The
water table is at or near the surface in spring and during
the peak of the irrigation season.
These soils are used for rangeland and wildlife habitat.
Some small areas are irrigated pasture.
• The potential native vegetation is dominated by
switchgrass, prairie cordgrass, autocrat's. alkali sacaton.
big bluestem, indiangrass, western wheatgrass, slender
wheatgrass, sedge, and rush. Cattails and bullrush grow
in the swampy spots associated with these range sites.
Potential production ranges from 4O00 pounds per acre in
favorable years to 3,000 pounds in unfavorable years. As
range condition deteriorates, the tall and mid grasses
decrease, production drops,and saltgrass,sedge,and rush
increase. The fanning and irrigation in adjacent areas has
increased the amount of salts on much of the acreage.
Management of vegetation on this soil should In' based
on taking half and leaving half of the total annual produc-
tion. Switchgrass, big bluestem, indiangrass, western
wheatgrass, pubescent wheatgnisss, intermediate wheat-
grass, tall wheatgrass, and tall fescue are suitable fur
seeding. The plants selected should met the seasonal
requirements' of livestock. For successful seeding, a firm
prepared seedbed is needed. A grass drill should he used.
Seeding early in spring has proven most successful. Til-
lage is needed to eliminate the undesirable vegetation.
Wetland wildlife, especially waterfowl, utilize this unit.
The wetland plants provide nesting and protective cover
as well as some food. The nearby irrigated eropland,
where wildlife obtain much of their Peal and find protee'
Live cover, makes this unit valuable to both wetland and
opuntand wildlife.
Openland wildlife, especially pheasant, use this unit for EXHIBIT
cover and nesting. Deer find excellent cover in some
areas. These valuable wildlife areas should be protected
from tire and fenced to prevent encroachment and
overuse by livestock. They should not be drained. Capa-
