Evaluating Best Management Practices (BMPs) for Nutrient Load Reductions in Tile-Drained Watersheds of the Great Lakes Basin

An optimal BMP scenario involves a multilayer approach that addresses nutrient losses at multiple points: field or source, edge-of-field, and watershed outlet. A multilayered BMP approach can ensure comprehensive nutrient management across different hydrological pathways and maximize the potential for reductions in nutrient loading in tile-drained agricultural landscapes under climate change.
