SOIL HEALTH PRACTICES ARE ACTIVELY PROMOTED AS A MEANS OF INCREASING CROP PRODUCTIVITY WHILE IMPROVING WATER QUALITY. YET THE IMPACT OF THESE PRACTICES ON AGRICULTURAL NUTRIENT LOSSES REMAINS UNCLEAR, PARTICULARLY FOR PHOSPHORUS IN FINE-TEXTURED SOILS. STAKEHOLDERS ARE CALLING FOR RESEARCH ON THE PHOSPHORUS LOADING IMPACTS OF SOIL HEALTH PRACTICES IN THE GREAT LAKES REGION. THE GOAL OF THIS PROJECT IS TO DETERMINE THE EXTENT TO WHICH SOIL HEALTH PRACTICES IMPACT SOIL HEALTH AND, IN TURN, AFFECT NUTRIENT LOSSES AT THE FIELD AND WATERSHED SCALES WITHIN THE WESTERN LAKE ERIE BASIN. OUR OBJECTIVES ARE TO: (1) QUANTIFY SOIL HEALTH PRACTICE IMPACTS ON SOIL HEALTH PROPERTIES, (2) QUANTIFY SOIL HEALTH IMPACTS ON NUTRIENT LOSS, AND (3) PROJECT WATER QUALITY IMPACTS OF SOIL HEALTH PRACTICES TO THE WATERSHED SCALE. WE WILL EVALUATE THE WATER QUALITY BENEFITS OF SOIL HEALTH PRACTICES AT MULTIPLE SCALES THROUGH FIELD STUDIES AND WATERSHED MODELING.
