In 2025, Wisconsin farmers Jim Stute and Tom Novak launched an on-farm research project to study the effects of spring nitrogen application on rye cover crops. The initiative examines if these applications can boost rye biomass and improve performance for following corn crops.
Why it matters
The study aims to determine if strategic nitrogen use can mitigate small yield decreases in no-till corn that often follow the use of rye cover crops. By increasing rye biomass, farmers hope to enhance natural weed suppression, erosion protection, and soil structure.
The study examines how spring nitrogen applications correlate with rye height and color under varying soil types. Findings aim to quantify whether these treatments influence the fertilizer needs of subsequent corn plantings.
The players
Jim Stute
He is a farmer involved in leading the on-farm research project testing nitrogen applications on rye.
Tom Novak
He is a farmer collaborating on the study to evaluate how cover crop management impacts corn yield.
The details
Farmers applied nitrogen to rye cover crops during early spring to observe growth patterns, noting that treated plants consistently appeared taller and darker. The research project, funded by the 2025 Nitrogen Optimization Pilot Program, is conducted under real-world farming conditions.
Timeline
The Nitrogen Optimization Pilot Program provided funding for the project throughout 2025.
Farmers apply nitrogen treatments to their rye cover crops in early spring.
Culture Shift
This project follows a pattern set by the 2025 Nitrogen Optimization Pilot Program to modernize regional nutrient management through on-farm experimentation. It highlights a growing movement among growers to integrate science-based nitrogen strategies into sustainable no-till systems.
Wisconsin growers may gain new insights into balancing rye cover crop biomass with corn production requirements. The results could eventually influence standard fertilizing routines for local no-till farmers seeking to maintain high yields while protecting soil health.
The takeaway
Farmers should monitor regional findings to see if nitrogen-treated rye improves their soil structure without hindering subsequent crop growth. Implementing data-driven cover crop management can be an effective way to optimize field inputs.
