Soil Chemistry and Phosphorus Retention Capacity of North Carolina Coastal Plain Swamps Receiving Sewage Effluent

摘要

Several hundred freshwater swamps in North Carolina currently receive municipal wastewater inputs. In the study researchers examined three Coastal Plain wetlands to (1) characterize their soil chemical properties, (2) determine short-term and long-term effects of effluent additions on soil chemistry, (3) estimate the phosphorus sorption capacities of these swamp soils and determine the relationship between P sorption capacity and soil chemistry, and (4) develop a predictive index to evaluate the P sorption potentials of other N.C. Coastal Plain swamps.
