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.
pH is an abbreviation for “power of hydrogen” where “p” is short for the German word for power (potenz), and H is the element symbol for hydrogen. Why a Danish scientist used a German word is Greek to me, but he was a scientist, and I’m not, so I’ll just go with the flow. The H is capitalized because it is standard to capitalize element symbols. So now you understand about as much as I do.
