<br />soil, generally on knobs or in sags where the soil material
<br />has been reworked considerably and a thin mantle of loess
<br />deposited.
<br />The soils in this complex take in water well and have
<br />moderate to high available water holding capacity. Chisel-
<br />ing can be used to break up plowpans that form if the
<br />soils are tilled when wet. In a few spots, flat fragments of
<br />limestone as much as 3 to 12 inches in diameter cover the
<br />surface.
<br />These soils are suitable for cultivation or as ranggeland.
<br />Iv'early all of the acreage is cultivated. In dryfarmed fields
<br />winter small grains, sorghums, and similar crops grow
<br />well. Erosion can be controlled If stubble-mulch tillage is
<br />used and these soils are summer followed after crops are
<br />harvested. In some fields emergency tillage is needed for
<br />reducing soil blowing. In addition to small grains and
<br />sorghums, alfalfa, corn, and sugar beets are suited in
<br />irrigated areas. In these areas crop residue and manure
<br />should be worked into the soil. Irrigated crops respond if
<br />fertilizer is applied.
<br />' On rangeland blue grams, western wheatgrass, little
<br />bluestem, and buffalograss grow well. These native grasses
<br />'can be reseeded if the soil is moist and well covered with
<br />`litter. Proper range use can be obtained by locating fences,
<br />water, and salt so that animals aze the entire area. Capa-

<br />Wages-Campus-Weld looms, 3 to 5 percent slopes
<br />z(WcCI occur mostly in the western part of the county. They
<br />occupy old, high land surfaces that have been covered with
<br />windblown silt. These areas generally occupy convex
<br />Fridges that trend southeastward. Some areas of Wages and
<br />;Campus soils are on side slopes adjacent ho nearly level
<br />'areas of Dawes loam, but the Weld soil does not occur
<br />!.in these areas.
<br />~' Wages soil makes up about 50 ercent of the complex;
<br />Cam us soil, 25 percent; and Weld soil, 15 percent. Wages
<br />'and ~ampus soils are on the slopes, and the Weld soil is on
<br />tthe narrow, convex ridgetops. These soils are so closely
<br />iassociated that it is not practical to map them separately.
<br />`Each kind of soil has a profile similar to the one described
<br />`for its series.
<br />F' Included in mapping were small areas of Platner soils
<br />that occupy the toe slopes of the ridges. Also included were
<br />a few small spots of Canyon soils near spots where lime-
<br />~ne crops out. The limestone is a hazard to farm machin-
<br />ery, Also occurring were a few small areas having slopes of
<br />~~ to 9 percent.
<br />`~"_-These soils take in water moderately well. Their avail-
<br />ble water holding capacity is moderate to high. Because
<br />slopes are gentle, runoff is considerable during heavy
<br />rains, which causes small rills to form. Plowpans tend to
<br />orm m the soils if they are tilled when wet.
<br />Soils in this complex are suitable for limited cultivation
<br />or as rangeland. Nearly all the acreage is cultivated. A
<br />'table practice in dryfarmed fields is stubble-mulch till-
<br />for controlling erosion and mauitaining filth and fer-
<br />~ty. Tilth and fertility are also maintained by working
<br />p residue into the soil, emergency tillage, and construct-
<br />terraces on the longer slopes. These practices also con-
<br />, rve moisture. In the irrigated areas, crops respond to
<br />pplications of fertilizer.
<br />On rangeland grasses grow well if fences, water, and salt
<br />properly placed so that livestock graze the entire range.

<br />Seedlings emerge quickly if the range is reseeded when the
<br />soil is moist and has a good cover of litter. Then, grazing
<br />should be deferred until the young plants are well estab-
<br />lished. Capability units IVe-1 (dryland) and IIIe-5 (ir-

<br />Wages-Eckley-Drs complex, 5 to 25 percent slopes
<br />(WeEI occupies areas along intermittent drainageways,
<br />principally Frenchman and Patent Creeks. These soils are
<br />so intermmgled that it is not practical to map them
<br />separately.
<br />Included with these soils immapping were nearly level
<br />to moderately sloping soils on stream terraces and chan-
<br />nel bottoms. The channel bottoms are shown on the soil
<br />map by a symbol for drainage. Also included were small
<br />areas where the soil is shallow over gravel and calcareous
<br />throughout.
<br />About 60 percent of this complex is Wages soils, 18 per-
<br />cent is Eckley soils, and 12 percent is Dix soils. Each kind
<br />of soil has the profile described as typical for its series. The
<br />rest of the complex consists of areas of Platner and Asca-
<br />lon soils. In hardland or sandy land areas, the Ascalon
<br />soils occur on the south banks of the streams and Platner
<br />soils are at the upper edges of side slopes.
<br />These soils take water at a moderate to rapid rate, Where
<br />they are shallow, their capacity to hold water is limited.
<br />If rains are heavy, runoff Is considerable and causes rill
<br />erosion. Also, extra water from runoff frequently concen-
<br />trates and floods the Dix soils. Erosion control darns could
<br />be built to control this water.
<br />The complex is not suitable for cultivation, mainly be-
<br />cause it is erodible, shallow, and sloping to steep. The
<br />areas should be seeded with native grasses. In the more
<br />accessible areas, overgrazinp~ is prevented by placing water,
<br />fences, and salt so that the livestock graze the entire range.
<br />Although reseeding may be difficult in some eroded or over-
<br />grazed areas, seeds germinate quickly if the soil is moist
<br />and covered with litter. Young plants should not be grazed
<br />until they are well established. Capability unit VIe-3

<br />Weld Series
<br />The Weld series consists of deep, well-drained, loamy
<br />soils that are nearly level to gently sloping. These soils are
<br />in the western and extreme northeastern parts of the
<br />county (fig 9). They formed in loamy eolian, or loessal,
<br />materials. In a typical llrofile the surface layer is about
<br />6 inches thick. It is grayish-brown loam in the upper part
<br />and dark grayish-brown loam in the lower part.
<br />The subsoil is about 10 inches thick and noncalcareous.
<br />The upper part is very hard, dark grayish-brown clay,
<br />and the lower part is hard, dark grayish-brown very fine
<br />sandy loam.
<br />The underlying material is very pale brown loamy ma-
<br />terial that contains many fragments of limestone as much
<br />as 1 inch in diameter.
<br />Because the surface layer of the Weld soils is a thin
<br />deposit of loam overlying a very slowly permeable sub-
<br />soil, runoff is rapid on moderately sloping areas. Hard-
