| Abstract: | Nitrogen runoff from pastures fertilized with animal manure, such as poultry litter, can result in accelerated eutrophication. The objective of this study was to evaluate the long‐term effects of grazing management and buffer strips on N runoff from pastures fertilized with poultry litter. A 12‐yr study was conducted on 15 small watersheds in Booneville, AR, using five management practices: continuous grazing, haying, rotational grazing, rotational grazing with an unfertilized buffer strip, and rotational grazing with a fenced unfertilized riparian buffer. Poultry litter was applied annually at a rate of 5.6 Mg ha−1. Concentrations and loads of total N, NO3–N, NH4–N, organic N, and total organic C in runoff varied intra‐ and interannually and coincided with precipitation trends. Overall, the greatest component of total N in runoff was organic N. Rotational grazing resulted in the highest concentrations and loads of all forms of N in runoff compared with other treatments, including the continuously grazed paddocks, which were grazed almost twice as much. Total organic C concentrations and loads in runoff were also higher from rotationally grazed watersheds than other treatments. Rotational grazing is considered a best management practice that typically reduces soil erosion; hence, the mechanism by which it caused higher N and C runoff is unclear. Nitrogen runoff losses from rotationally grazed pastures were reduced by 44% with unfertilized buffer strips, by 54% with fenced unfertilized riparian buffers, and by 52% by converting pastures to hayfields. Core Ideas: The largest portion of N in runoff was in the organic form.Rotational grazing resulted in higher N runoff than continuous grazing.Rotational grazing resulted in the highest total organic C loads in runoff.Buffer strips and converting pastures to hayfields reduced N runoff.Rotational grazing with a fenced riparian buffer reduced N in runoff.
