The effects of cattle manure application and duration on runoff quality with respect to N, P, and fecal coliform (FC) from fescue dominated pastures were measured at the University of Kentucky Maine Chance Agriculture Experiment Station. The impacts of runoff depth and timing of sample collection on these parameters were also assessed. Three simulated grazing treatments (ungrazed-no manure, continuous-3.7 AU/ha of manure once a week, rotational grazing- 14.8 AU/ha of manure every 4 weeks). Simulated runoff events occurred 4, 8 and 12 weeks after initial manure application. Runoff water was collected tested for N, P, and FC concentrations.
