40 Edge of Field Nutrient Losses: Measurements and Management: I

Oral Session
A05 Environmental Quality
Edge-of-field nutrient losses occur when commercial fertilizers or manures are land applied. Are setbacks an effective mitigation strategy? Can GPS/GIS be used as a tool for determining setback distances? Which plant species are effective? These topics will be discussed.
