LEAP-Legacies of Agricultural Pollutants: Integrated Assessment of Biophysical and Socioeconomic Controls on Water Quality in Agroecosystems

Widespread nitrogen (N) and phosphorus (P) fertilizer use threatens water quality and aquatic ecosystems. Agricultural best management practices (BMPs) have been implemented in an attempt to improve water quality, but time lags between BMP implementation and measurable water quality benefits are frequently observed. One reason is the slow release of N and P from legacy nutrient stores that accumulated in the landscape over decades of fertilizer application. At present, we continue to lack: (a) a comprehensive characterization of the nature, size and reactivity of agricultural N and P legacies, (b) integrated modelling tools to predict the timing and magnitude of water quality improvements achievable through BMPs, and (c) policy instruments that acknowledge time lags and balance trade-offs between short and long-term costs, benefits and risks.
