Alicia, Dean, Harvey, LaFonda, and Moriarty soils lack argillic horizons. Pastura soils have petrocalcic horizons at depths less than 20 inches. Witt soils are deeper than 36 inches to the calcic horizon and contain less than 15 percent fine sand or coarser in the control section. Permeability is moderate. Runoff is negligible on slopes less than 1 percent, very low on 1 to 3 percent slopes, low on 3 to 5 percent slopes and medium on 5 to 20 percent slopes.
Principal use is for livestock grazing, but also used for irrigated cropland and nonirrigated wheat.
The principal native vegetation is blue grama, hairy grama, galleta, sideoats grama, buffalo grass, and yucca. Irrigated crops are alfalfa, potatoes, and sugar beets. Central New Mexico, east-central Arizona and southwest Utah. The series is of large extent. Curry County, New Mexico, 1956.
