Brief Project Summary:

Nitrogen flows from the roots of soybeans to the tops mostly as nitrate (from the soil solution) and compounds known as ureides (the export product of nitrogen fixation from the nodules). The concentration of ureides in the plant is directly related to the number and vigor of the nodules. In our laboratory, we have developed a simple and direct method of analyzing soybean tissues for ureide content. It is our hope that this test might someday be offered by soil and plant testing labs, but more field calibration data are needed. The purpose of this proposal is to conduct inoculation studies in the field, and relate the response (yield, protein content) to the ureide levels in the plants...

Information And Results
Project Deliverables

If sites have low numbers of B. japonicum in the soil, and low soil nitrate levels, a response to inoculation is expected. The plants should have a deeper green color, better growth, and higher levels of ureides in the plants as a result of inoculation. The yield and protein content should be increased, and we will gain more field data on how to interpret a ureide test.

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.
