Brief Project Summary:

This soil fertility project includes correlation and calibration work for several plant-essential nutrients which are important to crops produced in Louisiana. The overall goal is to provide more robust fertilizer management guidelines for sustainable and profitable soybean production in Louisiana. Work intends to validate and update fertilization rates based on the Mehlich-3 sol test ratings for corn and soybean production, evaluate the influence of lime application on available soil macro- and micro-nutrients concentration on an acid upland soil continuously corn-soybean rotation, conduct on-farm evaluations of different approaches for N-recommendations, document and address nutritional problems associated with soils with pH issues, and document the benefits of silicon fertilization in wheat, corn and soybean production.

Key Benefactors:
farmers, agronomists, Extension agents

Information And Results
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.
