The A horizon ranges frotu 4 to 3 inches in thickness. The B2t horizon ranges from heavy silty clay loam. to clay. When the soil is moist, eery nark grayish-Brown or darker colors extend to a depth of 20 to 50 inches. In most areas free lime has been leached to a depth of 60 inches, but as few areas are calcareous at as depth of 10 inches. Pleasant soils have a more uniform color in the subsoil than have Rago soils. :also, Pleasant soils lack the distinct layer of accumulated time that occurs in Rago soils. Pleasant loam (0 to 3 percent slopes) (Ps) occupies the acreage in the south-central part of the coulaty at the west and northwest edges of the sanclhills. Included with this soil in lnapl_ring were areas of Rago -Intl hunia lolams. Also included were playas and a few areas having a surface layer of light clay loam. Pleasant loath is deep and takes water slowlv, but it does not release wwater• readily- to plants. Kunod• is slog-. 'phis soil is suitable for cultivation, and about half the acreage is cultivated. In dryfarmed area`, crops alld grass for pasture or range are suited. Also suited are irrigated crops, pasture, or hay-. This soil periodically is flooded after heavy rains. If the. soil is tilled when wet, plowpans teas[ to form in the tapper part of the subsoil. Periodic chiseling wyllen the soil is dry breaks up the, ploww•pan. ?Stubhle Iltudching or use of crop residue o-enerally helps to reduce erosion in dryfartued areas, although the. soil is nearly level, irrigated fields re- quire, Reveling so that. water spreads uniformly. Practices for controlling soil blowing and for maintaining fertility= are careful inanagenient of irrigation water and working. crop residue into the soil. Blue grama, buff alocrass, -Intl western wheat;-rass grow vigorously on this soil. In cultivated or overgrazed areas, reseeding is desirable. if the soil is rnoist an([ covered with litter. All grazuug should he deferred until the ,era's forms a good root system. Overgrazing can be avoided if salt, watering points, and fences are, located so that animals braze the entire ranee.

'I'hese soils occur on uplands and ,ire nearly level or gently sloping. They occupy broad, that areas and are rxtellsiVe thDattghout tile CotultV. In a typical profile the plow layer is _rray isla l,rnwt n lease shout 5 inchc,s thlok (ticY, t;). It is easily worked. The subsoil is about 21 inches thick. The tapper part. is dark grayish-brown, slightly hard loam and hard clay loam. The middle part, is dark-gray, hard siltv clay loam, en . and the lower part is pale-brown, slightly hard silty clay loam that is strongly calcareous and contains visible lithe. The underlying material is very pale brown loam and silt loath that. is very strongly -'all•areolas and Voiltaills visible [link'. Surface runotf is medium, because these soils are not more than gently sloping and have a moderately perme- able surface layer. They have a high capacity to hol water and ire high in natural fertility. Except for a few shall areas, the. Rago soils are dry farmed. `"inter wheat., barley, and sorghums are the inai crops. Some oats are, grown in it few areas. The native veget;atiola consists mainly of western wlteatgrass and bit r;l'alua grasses.
