Brief Project Summary:

Past research has tried to identify soybean safe planting conditions into terminated or living rye and water availability is key. This project looks to identify a soil moisture threshold that indicates when to terminate the rye so soybean yields are protected. Researchers will gather information about soil moisture in each treatment consisting of seven rye termination dates and five soil moisture check plots. Soybean emergence, maturity, and yield data will be collected. Soil moisture readings will be compared to soybean growth and yield data to determine when moisture levels become risky to soybeans.

Key Benefactors:
farmers, agronomists, extension specialists

Information And Results
Project Deliverables

This project has several levels of deliverables. During the course of the experiment, there will be several project updates. The most common exposure this project will receive occurs at on-site field tours (if possible next year). This project has generally been featured at several (~3x per year) events including trainings for consultants, Extension agents, and other researchers, as well as being featured at our field days and row crop tours. The ultimate products of this project include research reports and likely a scientific publication, but more importantly it will result in a decision support tool, likely linked with NDAWN (described below). This project has already helped immensely to shift the focus of soybean producers and advisors toward soil health conversations, regardless of their intentions for specifically using rye as a relay crop.

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.
