vmc~ai genes Lescnpuun - i.rs~i,rs.rv genes <br />rake c ui ~ <br />The A horizon is mildly to moderately alkaline. <br />Volume of coarse fragments in the C ranges from 35 to 80 percent with 5 to 30 percent larger than 3 <br />inches. <br />COMPETING SERIES: The closely related Pala soils lack a calcic horizon. <br />GEOGRAPHIC SETTING: Cascajo soils aze on terrace edges, hills, knolls and ridges. Slopes range <br />from 2 to 40 percent. The soils formed in very gravelly and sandy alluvium that ranges from about 4 to <br />20 feet thick over shale or sandstone. Mean annual precipitation is about 12 inches and average annual <br />temperature is about 52 degrees F. <br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Otero, Harvev, Stoneham, and the <br />competing Pala soils. Otero soils lack a calcic horizon and aze coarse, loamy. Harvey and Stoneham <br />soils are fine, loamy. <br />DRAINAGE AND PERMEABILITY: Excessively drained; rapid permeability; slow runoff. <br />USE AND VEGETATION: Primarily used for grazing, dominantly short and mid grasses. Many areas <br />are used as source of sand and gravel. <br />DISTRIBUTION AND EXTENT: Eastern Colorado and New Mexico. The series is of moderate <br />extent and individual areas are long and narrow, usually bordering major drainageways. <br />MLRA OFFICE RESPONSH3LE: Salina, Kansas <br />SERIES ESTABLISHED: Upper Rio Puerco Reconnaissance Soil Survey, New Mexico, 1940. <br />REMARKS: Cascajo soils have been correlated in Prowers County, Otero County, Bent County, <br />Crowley County, and Pueblo County Area of Colorado, and in all areas are sandy-skeletal. <br />National Cooperative Soil Survey <br />U.S.A. <br />http://ortho.ftw.nres.usda.gov/cgi -bin/osd/osdname. cgi?-P <br />4/29/2004 <br />
