Brief Project Summary:

Three major phosphorus sources have contributed to the degradation of water quality in the Chesapeake Bay: land driven phosphorus, mobilized phosphorus from bay sediments and imported phosphorus from the ocean. Sufficient information about of different land driven phosphorus sources is not available. This research collects samples from natural sources (soils, sediments), legacy phosphorus (stores in soils and catchments), agricultural related sources (fertilizers and manures) and wastewater sources. Analyzing samples collected from lands, river waters and the bay that retain these sources generates an isotope database to interpret data obtained from the bay.

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
