The AgBMPDB includes performance data and metadata that document the many variables that affect BMP performance, such as geographic area, field conditions (e.g., soils, slopes), in-field practices (e.g., tillage, nutrient management) and edge-of-field practices (e.g., buffers, constructed wetlands). The initial release of the AgBMPDB focuses on row crops, particularly corn and soybeans. The initial data summary indicates that no-till and riparian buffers can provide significant reductions in phosphorus and sediment loads. Nutrient management and controlled drainage can provide significant reductions in nitrate loads. Cover crops do not show significant pollutant reductions, but there is wide variability among the studies indicating the effects are confounded by other variables. As the database grows, more advanced meta-analyses of the data contained in the database may be conducted and eventually support science-based decisions.
