Brief Project Summary:

A past survey by the University of Kentucky showed that only 18% of the fields had enough compaction to warrant fall ripping. However, in most falls, farmers subsoil a much higher percentage of the fields. This study is designed to assess the effects of fall tillage on the subsequent crop yield. If the University estimates are correct, many farmers are wasting money on fall tillage, however, if farmers are correct and compaction is a greater problem than expected, there is a need to for a change in the management recommendation.

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.
