• soils are on hills, fan terraces and valley fills. Slope is 0 to 5 percent. The soils formed in alluvium derived from <br />calcareous sandstone and shale and limestone. The elevation is 4,500 to 6,500 feet. The mean annual <br />precipitation is 10 to 13 inches, but has ranged to 17 inches in the past. The mean annual soil temperature ranges <br />from 48 to 59 degrees F. The frost-free period is about 150 to 190 days. <br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Asparas, Deama, La Fonda, Pastura, and the <br />competing Harvey soils. Asparas soils have an argillic horizon. Deama soils are shallow to limestone. La Fonda <br />soils lack celcic horizons. Pastura soils have petrocelcic horizons. <br />DRAINAGE AND PERMEABILITY: Well drained; slow runoff; moderate permeability. <br />USE AND VEGETATION: Used mainly for rangeland. The vegetation is sideoats grama, black grama, blue <br />grama, soapweed, and sacahuista. <br />DISTRIBUTION AND EXTENT: Southeastern and south-central New Mexico. The soils are of moderate extent. <br />LRA OFFICE RESPONSIBLE: Temple, Texas <br />• SERIES ESTABLISHED: Chaves Counly (North Part), New Mexico, 1981. <br />REMARKS: Diagnostic horizons and features recognized in this pedon are: <br />Ochric epipedon: The zone from 0 to 6 inches. (A horizon). <br />Cambic horizon: The zone from 6 to 31 inches. (Bw horizons). <br />Calcic horizon: The zone from 31 to 60 inches.
