Two of the most important chemical processes which occur in the salt marsh environment are the cyclic regenerations of nitrogen and phosphorus. The present work is a study of the occurrence and distribution of the important inorganic nitrogen and phosphorus forms at various locations in a Georgia salt marsh. A particular problem involving the fixation of ammonium by clay minerals was examined. Sediments and interstitial waters from the cores were analyzed for the important inorganic nitrogen and phosphorus species. Both exchangeable and nonexchangeable ('fixed') ammonium were found in the marsh sediments. The three important inorganic phosphorus species A1-PO4, Fe-PO4, and Ca-PO4 were found in the marsh sediments in varying abudances. The major source of both inorganic nitrogen and phosphorus in the sediments is the marsh grass Spartina alterniflora.
