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

open access: yesJournal 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.
