Annona, Derly, Etoile, and Freestone soils have argillic horizons. Annona and Etoile soils are above on slightly higher positions. Derly and Freestone soils are on similar or slightly lower terrace positions. The competing Eastham and Garner series have slopes less than 3 percent and are on lower positions. It is well drained, with very slow permeability, and high runoff.
Infiltration is rapid when the soil is dry and cracked, but very slow when it is wet.
Most areas have been cultivated in the past but now are used for pasture. Bermudagrass and kleingrass are adapted and are grown on this soil. Some areas are cultivated to grain sorghum or small grain. Native grasses include bluestems, Indiangrass, buffalograss, tridens, and threeawn. There are a few scattered mesquite in some areas.
