The over-arching objective of this project is to evaluate sources and environmental controls of phosphorus (P) mobilization from the landscape, focusing on soluble P, and to use this information in computer models to inform strategies for basin-wide P reduction. Reductions could be realized by implementation of BMPs and conservation practices targeting either direct dissolved P or particulate P effluent from agricultural fields, or indirect P loads due to remobilization of stored P through changes in discharge, sediment supply or P form (dissolved vs. particulate).
Three specific objectives include:
There are three primary deliverables for this project. These include a high resolution water chemistry database with two years of sample collection capturing spatial and temporal variability within the Le Sueur Basin. The second includes a watershed scale SWAT model (Soil and Water Assessment Tool) of the Le Sueur River watershed which will include treatments for multiple P pools, including particulate and reactive P. The third deliverable would include technical reporting, as well as peer-reviewed publications and conference presentations.
