Understanding rye cover crop effects on corn

November 7, 2016

The effect of cover crop on crop yields, soil health, and nitrate-nitrogen (N) leaching is complex and variable from year to year. From an environmental point of view, the higher the rye biomass production at termination day, the higher the likelihood of increasing soil organic carbon and decreasing N leaching. However, common asked questions are whether the magnitude of rye biomass is proportionally related to yield benefits or losses and how much water and N does rye use?

FACTS is an ongoing project developed to forecast and evaluate real-time soil-crop dynamics in specific ISU fields. Predictions and measurements will be frequently updated as new information becomes available during the growing season.
