Their subsoil, about 13 inches thick, is limp, pale-brown clay or silty clay in the upper part and is clay in the lower part. Beds of partly consolidated, clayey shale accttr at a depth of about 39 inches. The major soils in this association areslowly to moder- ately permeable. Runoff generally is moderate to rapid. Erosion normally is slight to moderate, but it is severe m some cultivated areas. i+finor parts of this association are the Thedalund, Sam- ail, and Fondis soils on uplands and Loamy alluvial land along streams. Jlost of this association is used to pasturo cattle or as wildlife habitat. The native grasses are western wheat- grass, blue grama~ plains bluegrass, and pricklypear cac- tus. ~lntere the sods are cultivated, wheat is rho principal crop. Stubble mulching, terracing, contour stripcropping, and other intensive conservation practices are needed to help control erosion, conserve moisture, and maintain or increase the growth of crops. i\Iany homes are in this asso- ciation in the tcestern part of the county. Gravel roads are about 3 to 3 miles apart through most of the association. One improved road crosses the middle of the Lowry Bombing Range from west to east. Nunn-Bresser•Ascalon Association Deep; steady level and undulating, loamy soils that haste a clayey to Zoamy subsoil; developed in outuas1c; on scp- lanrls and terraces This association is on uplands in the western and central parts of the county. hlost areas are undulating and hate slopes ranging from 0 to 4 percent. The soils are deep anti bare a clayey to loamy sttbsotl. Tltis association occupies about 13 percent of the cou+tt}'. aliottt 60 percent is made up of ?~TUnn soils, 15 pet'cent of Bresset• soils. 15 percent of _lscalon soils, aitd the remain- ing 10 percentof minorsoils. The Bunn soils occur in the more nearly level areas of this as=_ociatioit. They Mace agrayish-brown loam surface la}'er about 3 inches thick. Their subsoil is brownish clay loam, light clay, and sandy clay loam nbortt 19 inches thick. Lime occurs at a deptdt of about 22 inches. The Bre=_ser soils occur' on knobs and in rolling areas. Their surface layer is dark grayish-brown sandy loam about 5 inches thick. The subsoil estends to a depth of about 2S inches. It is hard or very hard when dry. It is dark-brown sandy loam ht the upper part, brawn sandy clay loam iii the middle part, and light-brown sandy login in the lower part. Tlte -lscalon soils are similar to the Bresset• soils bttt have a slightly grayer subsoil and lime at a depth of about 17 inches.
