These soils are so closely <br />ciated that it is not practical to map them separately. <br />kind of soil has a profile similar to the one described <br />its series. <br />ncluded in mapping were small areas of Platner soils <br />t occupy the toe slopes of the ridges.

Their avail- <br />,:,i;ovater holding capacity is moderate to high. Because <br />'nes are gentle, runoff is considerable during heavy <br />is, which causes small rills to form.

A <br />t'a`ble practice in dryf armed fields is stubble -mulch till - <br />controlling erosion and maintaining tilth and fer- <br />ty. Tilth and fertility are also maintained by working <br />pYiesidue into the soil, emergency tillage, and construct - <br />;terraces on the longer slopes. These practices also con- <br />ve moisture. In the irrigated areas, crops respond to <br />ilications of fertilizer. <br />)n rangeland grasses grow well if fences, water, and salt <br />properly placed so that livestock graze the entire range. <br />23 <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.

These soils are <br />so intermingled that it is not practical to map them <br />separately. <br />Included with these soils in mapping 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, 1S 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 sanely 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. 111so, extra water from runoff frequently concen- <br />trates and floods the Dix soils. Erosion control clams 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, overgrazing 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 />germinate quickly if the soil is moist <br />grazed areas, seeds <br />and covered with litter. Young plants should not be grazed <br />until they are well established. Capability unit Vle-3 <br />(clrylancl) ; Wages soils are in Loamy Plains range site and <br />windbreak suitability group 1; Eckley soils are in Gravel <br />Breaks range site and windbreak suitability gzoup 3; and <br />Dix soils are in Gravel Breaks range site and windbreak <br />suitability group 2. <br />'Veld 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 profile the surface layer is about <br />6 inches thick. It is grayish -brown loam in the upper part <br />and Clark grayish -brown loam in the lower part. <br />The subsoil is about 10 inches thick and nonealcareous. <br />The upper part is very hard, Clark grayish -brown clay, <br />and the lower part is hard, Clark graylsh-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 I inch in diameter. <br />Because the surface layer of the Weld soils is a thin <br />deposit of loans overlying a very slowly permeable sub- <br />soil, runoff is rapid on moderately sloping areas.
