Harris soils are very poorly drained Haplaquolls, and lower in the landscape on marshes. Viterbo soils have a argillic horizon and are on the same to slightly higher positions in the landscape. Beaumont soils are poorly drained and very slowly permeable. Runoff is low. Rice is usually grown on a 1 in 4 year rotation.
Improved pastures are mostly bahiagrass.
Native grasses are mainly little bluestem, indiangrass, eastern gamagrass, switchgrass, Flordia paspalum, big bluestem, brownseed paspalum, knotroot bristlegrass, sedges and rushes. In some areas pine and hardwood trees have encroached. The Beaumont series has been mapped extensively from Beaumont to Victoria. However, the soils mapped in the Beaumont series west of the Trinity River will be included in the Bacliff or other series. The series is of moderate extent.
