Grandfield series: are on stream terraces.
DRAINAGE AND PERMEABILITY: Well drained. Moderate permeability. Runoff is very low on 1 to 3 percent slopes and is low on 3 to 5 percent slopes.
USE AND VEGETATION: Mainly used as rangeland, however; some areas are cultivated to small grains, cotton and forage sorghums. The native vegetation is mainly mid and tall grasses with scattering of oaks. Mesquite, oaks, lotebush, and cactus have invaded most rangeland areas. Post oak and blackjack oak have formed dense canopies in some of the sandy areas.
DISTRIBUTION AND EXTENT: Central Great Plains, North Central Parries; LRR H; MLRA 80B; and possibly Central Rolling Red Parries, MLRA 80A. The series is of moderate extent.
