<br />10-Bankard sandy loam, 0 to 3 percent slopes. This
<br />is a deep, somewhat excessively drained soil on flood
<br />plains at elevations of 4,450 to 5,000 feet. it formed in
<br />stratified recent alluvium along streams and rivers. In-
<br />cluded in mapping are numerous sand and gravel bars
<br />and small areas of noncalcareous soils.
<br />Typically the surface layer of this Bankard soil is
<br />brown sandy loam about 4 inches thick. The underlying
<br />material to a depth of 60 inches is pale brown calcareous
<br />sand stratified with thin lenses of sandy loam, loam, and
<br />fine gravel.
<br />Permeability is moderately rapid. Available water
<br />capacity is low. The effective rooting depth is 60 inches or
<br />more. Surface runoff is slow, and the erosion hazard is
<br />low.
<br />This soil is suited to limited cropping. It is sandy and
<br />subject to flooding. Pasture is the best use. Tall wheat-
<br />grass, tall fescue, and annual sweetclover are some of the
<br />most suitable crops. Light, frequent imgation by furrows
<br />and flooding is best. Commercial fertilizer improves the
<br />ount and value of forage produced.
<br />he potential native vegetation is dominated by
<br />witchgtasv, indiangrass, sand bluestem, sand reedgrass,
<br />sideoats grams, needleandthread, and blue grams. Much
<br />of this range site includes other soils and vegetation in
<br />such a complex pattern that it is difficult to map them
<br />separately. Potential production ranges from 2,500 pounds
<br />per acre in favorable years to 1,500 pounds in unfavorable
<br />years. As range condition deteriorates, the tall and mid
<br />grasses decrease; blue grams, sand dropseed, and (orbs
<br />increase; and forage production drops. Undesirable weeds
<br />and annuals invade the site as range condition becomes
<br />poorer.
<br />Management of vegetation should be based on taking
<br />half and leaving half of the total annual production. Seed-
<br />ing is desirable only in areas large enough to interseed or
<br />to prepare a seedbed. Switchgrass, sand bluestem, sand
<br />rcedgrass, sideoats grams, little bluestem, blue grams, pu-
<br />bescent wheatgrass, and intermediate wheatgrass are
<br />suitable for seeding. This soil can be seeded by using an
<br />interseeder or a firm, clean sorghum stubble. A grass drill
<br />is required. Seeding early in spring has proven most suc-
<br />cessful.
<br />This soil is generally not suited to the establishment
<br />and growth of trees and shrubs. Onsite investigation is
<br />needed to determine feasibility and possible tree and
<br />shrub species.
<br />r Wildlife is an impo~t secondary use oC this soil. The
<br />cropland areas provide favorable habitat for ring-necked
<br />pheasant antl mourning dove. Many nongame species can
<br />be attracted by establishing areas for nesting and escape
<br />cover. Far pheasants, undisturbed nesting cover is essen-
<br />tial and should be included in plans for habitat develop-
<br />ment, especially in areas of intensive agriculture. Range-
<br />land wildlife, for example, deer and antelope, can be at-
<br />tracted by managing livestock grazing and reseeding
<br />where needed.
<br />This soil is not suited to urban or recreational develop-
<br />ment because of the flood hazard. Capability subclass
