Brief Project Summary:

Research since 2004 has focused on developing databases to redefine soil-test based P and K recommendations for soybeans. Soil testing procedures were updated in 2006 and required that soil test recommendations be changed too. Changes were based on a combination of philosophy and preliminary research results. Meanwhile precision agriculture and its relationship to crop fertilization practices has become the focal point of crop nutrition management programs. This project is aimed at validating the accuracy of soil-testing based on fertilizer recommendations regarding soybean yield response to P and K fertilization. Research evaluates recommendations with new and unique data and refines recommendations based on the research responses used to build the database.

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.
