The objective of this study was to evaluate the mechanisms and effectiveness of vegetated buffer zones or borderland areas in reducing pollutional impact on rainfall runoff from sites used for land application of livestock and poultry manure. The effect of grass buffer-zone length on the reduction of pollutant concentration and mass in runoff from land application areas was studied over a nine-month period for several different buffer-area length/application-area length ratios. Also, one-dimensional mathematical models were developed to investigate the effects of dilution and infiltration. The model and experimental results suggest that infiltration is the major factor affecting buffer-zone length.
