ASSESSING POLICIES TO IMPROVE WATER QUALITY IN AGRICULTURAL LANDSCAPES

Abstract

Agricultural activities depend on applications of nitrogen, phosphorous and potassium to soils. However, these nutrients may leach into groundwater or run off into surface water, with a detrimental effect on water quality in the watershed. Location-specific knowledge about the costs of beneficial management practices (BMPs) and how farmers make nutrient management decisions are needed to develop and implement effective water quality policies, programs and incentives. This information is important for federal and provincial governments, conservation authorities, environmental non-governmental organizations, farmers and others concerned with nutrient loading to surface waters.
