Brief Project Summary:

Recent agricultural trends focus on soil management practices for maintaining physical, chemical and biological components of soil fertility that together comprise soil health. Recommendations to improve soil health focus on practices with the greatest potential to increase organic matter and nutrient cycling by biological processes. This research intends to assess changes to soil properties after introducing a winter wheat cover crop to a long-term corn and soybean rotation under different tillage systems, compare crop yields from different tillage systems with and without a cover crop and devise recommendations for cover crop use in corn-soybean rotations under a soil health management plan as promoted by federal agencies.

Key Benefactors:
farmers, agronomists, extension agents

Information And Results
Final Project Results

This study examines the effects of introducing a winter wheat cover crop into a long-term soybean and corn crop rotation in North Carolina’s piedmont soil, considering a range of tillage approaches. Addition of cover crops can add challenges to crop and soil management, but many studies have shown that cover cropping improves soil conservation. The study will help inform North Carolina growers about short-term effects of introducing cover crops on crop yield and soil properties

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.
