Brief Project Summary:

We will investigate the pool of soluble nitrogen (N) deep in the soil which may represent an opportunity to simultaneously reduce N pollution and enhance profitability on 100,000s of cropland acres. Building on our previous research on nitrogen uptake by cover crops, we will develop practical early-planted winter cereal and brassica cover crop systems capable of capturing 50-200 lbs./acre of N in fall and releasing it for crop use in spring. We hypothesize that such practices will increase yields and reduce fertilizer requirements while reducing the nitrogen loading from farms in the Chesapeake Bay watershed. It is proposed that the on-farm trials will generate important information on how...

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.
