The Beauregard series consists of very deep, moderately well drained, slowly permeable soils that formed in loamy alluvial sediments of Pleistocene age. These soils are on broad, nearly level and gently sloping Coastal Plains. They are saturated for short periods during winter and early spring.
Water runs off the surface at a medium to slow rate.
Slope is dominantly 1 to 3 percent but ranges from 0 to 5 percent. Beauregard silt loam on a concave 2 percent sideslope in pasture. Solum thickness ranges from 50 to 90 inches. Depth to horizons that contain more than 5 to 30 percent plinthite ranges from 15 to 40 inches. Mottles with 1 or 2 chroma are at depths of 12 to 30 inches below the soil surface.
