| Popis: | The historical increase in phosphorus fertilizer application on commercial cranberry bogs from ∼1960 to 2008 is associated with the decline in water quality of White Island Pond, Plymouth/Wareham, Massachusetts. A total maximum daily load (TMDL) and a memorandum of agreement (MOA) with cooperating groups required specific cranberry bog management practices to restore the lake. We used a cooperative approach among the University of Massachusetts, the growers, and the town with the assistance of a series of US Environmental Protection Agency 319 Program grants focusing on reduced fertilizer rates, discharge diversions, and an aluminum treatment of the lake to address the excess phosphorus inputs. In the East Basin of the pond, where total phosphorus (TP) summer concentrations previously averaged 82 μg/L, the concentrations dropped 41% over 4 years to 48 μg/L after fertilizer reductions and diversions of bog discharge floodwaters occurred at the cranberry bogs. After this source of phosphorus was con... |
