Advantages to a reduction in tillage can include improved aggregation and water infiltration, reduced soil loss and increased organic content and biological population and diversity in the soil, and aggressive tillage can potentially increase root diseases that are favored by warmer soils. Conversely, tillage can decrease incidence and severity of root diseases that tend to be less common in drier and warmer soils. However, concern about yield reductions or increased disease potential due to cool and wet soil conditions may limit adoption of high-residue systems for corn-soybean rotations on the poorly-drained soils that dominate much of Eastern North Dakota and Western Minnesota. The...
1. Improved knowledge on the effect of tillage on soil health, including SCN population dynamics.2. Recommendations for producers with regard to tillage and soil health.
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.
