Runoff is low on slopes less than 1 percent, medium on 1 to 3 percent slopes, and high on 3 to 5 percent slopes. Internal drainage is very slow. Extensively cultivated in the past, but now mostly in unimproved pasture. Some areas are farmed to cotton, grain sorghum, peanuts, and corn. Native vegetation is bunch grasses such as bluestems, Indiangrass, and Purple top.
Common trees consist of post oak, blackjack oak, elm, and hackberry.
Mainly in east central Texas. The soil is extensive. Classification change from Udertic Paleustalfs to Oxyaquic Vertic Paleustalfs based on recognition that these soils have short periods of iron reduction and oxidation evidenced by small zones of iron concentration and diffuse zones of iron depletion within 40 inches of the surface. In addition, associated soils have demonstrated the same micromorphological responses to short periods of oxidation and, to a lesser extent, reduction. Ochric epipedon - 0 to 14 inches.
