Abstract

Cover crops are valued by a growing number of Midwest corn and soybean growers for their ability to improve soil quality, combat soil compaction, minimize soil erosion, maximize soil nutrient capture, and protect water quality. This project allowed Iowa Learning Farms to collect significant additional data on Iowa cover crop production.

Key Question

What is the long-term impact of cereal rye usage on cash crop yields?

Findings

After seven years of continuous cereal rye cover crop usage, this project clearly shows that the impact of cover crop production on yield is neutral. Since this is on-farm research being conducted by farmer partners, it makes the finding even more important and eliminates one of the major concerns about cereal rye cover crop usage.
