Interpretive Summary:

Technical Abstract: Phosphorus transport from land-applied manure could potentially threaten water quality. Flue gas desulfurization (FGD) gypsum use as soil amendment could potentially minimize P loss. Thus, field studies were conducted to evaluate if FGD gypsum could reduce surface water runoff as well as the extractability of P from soil. The studies were conducted in bermudagrass pastures on fine sandy loam soils of the Southeastern USA. Results were discussed on the impact that FGD gypsum application has on P retention in soil and the losses with surface water runoff.
