Covering over 3 million acres and extending from Mexico through Louisiana. Just at sea level or a couple of feet above, it also contains areas of salt-water marsh and drainage is slow. The water table is either at or just below the surface. Used mostly for cattle grazing, or wetland wildlife refuges, residents have developed wonderfully bountiful gardens by amending soils.

Good healthy plants can fend off disease and destructive insects. The absence of these microorganisms and larger organisms such as earthworms, result in compacted, lifeless soil. Lifeless soil, of course, cannot sustain life.
