A short history of the phosphorus index and Andrew Sharpley's contributions from inception through development and implementation

Journal of Environmental Quality, EarlyView.
Abstract In the 1980s, growing recognition of agricultural phosphorus (P) sources to surface water eutrophication led to scrutiny of animal feeding operations. In 1990, the USDA‐Natural Resources Conservation Service (NRCS) invited prominent scientists to find a solution. It was at an initial meeting that Dr. Andrew Sharpley suggested that P assessment

Balancing agriculture and environment: Andrew Sharpley's nutrient, soil, and water management legacy

Journal of Environmental Quality, EarlyView.
Abstract Managing agricultural phosphorus (P) to balance food security and water quality priorities is a massive challenge fraught with uncertainty and competing interests. Throughout his career, Andrew Sharpley addressed this challenge by building our understanding of the fundamental principles and processes that control P behavior in agricultural ...

A review of the development and implementation of the critical source area concept: A reflection of Andrew Sharpley's role in improving water quality

Journal of Environmental Quality, EarlyView.
Abstract Critical source areas (CSAs) are small areas of a field, farm, or catchment that account for most contaminant loss by having both a high contaminant availability and transport potential. Most work on CSAs has focused on phosphorus (P), largely through the work in the 1990s initiated by Dr.
