Contribution of legacy phosphorus to watershed outcomes, phase 2 - SWAT modeling

This $110,000 cooperative agreement from the United States Department of Agriculture Agricultural Research Service will fund Phase 2 of the project "Contribution of Legacy Phosphorus to Watershed Outcomes, SWAT Modeling" at The Ohio State University from December 2021 through November 2025.

Under the agreement, The Ohio State University will utilize the Soil and Water Assessment Tool (SWAT) to model how legacy phosphorus in agricultural soils contributes to water quality outcomes within watersheds. This work supports the Agricultural Research Service's Agricultural Research Basic and Applied Research program (CFDA 10.001), which provides scientific and technical knowledge to support agricultural production. By further developing watershed-scale phosphorus modeling capabilities, this cooperative agreement aims to advance understanding of nutrient management needs and inform strategies to improve water quality.
