Bernard soils have argillic horizons. Francitas soils are on similar to slightly lower positions and occur mainly at elevations less than 50 feet above sea level. Pledger soils are on lower floodplains positions. Moderately well drained. Permeability is very slow.
Water enters the soil rapidly when cracked, but very slow when wet and cracks are closed.
Runoff is low on 0 to 1 percent slopes, medium on 1 to 3 percent slopes, high on 3 to 5 percent slopes, and very high on 5 to 8 percent slopes. Mainly in cultivation and native pasture. Crops are corn, cotton, rice, and grain sorghum. Native grasses include little bluestem, indiangrass, eastern gamagrass, switchgrass, big bluestem, and brownseed paspalum. Most areas have scattered live oak, water oak, elm, hackberry, and huisache trees.
