Dothan and Orangeburg soils are very extensive in the eastern part of the Lower Coastal Plains. They have loamy subsoils and sandy loam or loamy sand surface layers. Smithdale and Troup soils are very extensive in the western part. These soils have loamy subsoils and loamy sand or sand surface layers. Most slopes are less than 10 percent.
Major crops are corn, peanuts, soybeans and horticultural crops.
Timber products and hogs are very important. Elevations range from sea level to 500 feet. The soils are not extensive but important where they are found along streams and river terraces. They are derived from alluvium deposited by the streams. Cahaba, Myatt, and Urbo series represent major soils of this area.
