Elevated soil phosphorus (P) concentrations on agricultural land from the application of P in fertilizers and animal manures have increased the potential for excessive P losses in runoff to nutrient-sensitive waters. This study was conducted to determine P losses in runoff from agricultural land in the Piedmont region (North Carolina) of the southeastern USA with varying soil (Typic Rhododult) P levels resulting from past applications of broiler litter and inorganic P fertilizers.
