Brief Project Summary:

This research project builds on existing research to identify major sources of phosphorus in the Chesapeake Bay. Three major sources have contributed to the degradation of its water quality: the land, bay sediments and the ocean. Not all phosphorus is bio-available, meaning that some is less concerning for water quality. This study tracks P sources, differentiating between available and unavailable “pools” of the nutrient on farms around the Chesapeake Bay. Using a process called isotopic fingerprinting, work attempts to identify sources and variations in P. Efforts aim to identify non-agricultural and legacy phosphorus export from East Creek, Crisfield, Maryland, and identify the isotopic signatures of different phosphorus sources present in the Chesapeake 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.
