On-Farm

Trial Network

An Opportunity for Illinois Farmers to Discover Agronomic Solutions

The On-Farm Trial Network through the Illinois Soybean Association (ISA) is a program for Illinois farmers and organizations interested in participating in field-scale crop trials. The On-Farm Trial Network functions as the bridge between Illinois farms and the research generated by universities and industry experts. On-farm trials are an integral step in translating how small-plot or greenhouse research can apply to cropping environments. They allow for testing across a wider range of weather, soils and locations across Illinois.

2025-2026 Field Trials Open for Enrollment

The Illinois Soybean Association is now recruiting farmers to participate in on-farm research evaluating cover crop biomass and weed suppression. The trial will measure how cereal rye and winter barley impact biomass growth and weed control ahead of the following soybean crop.

Cover Crop Biomass Trial Details: 

  • Number of Locations: 4 on-farm sites

  • Geographic Scope: Statewide

  • Ideal Fields: No-till or reduced/minimal tillage

Click here for the full protocol. Participating farmers will contribute to research that supports stronger weed management and soil health practices across Illinois.

Enrollment is now open. Questions? Contact Deanna Burkhart, Producer and Field Services Administrator, at deanna.burkhart@ilsoy.org or 309-307-9366.

Types of Trials

Our agronomy team works with farmers and others within the industry to deploy and manage trials belonging to one of three categories:

Legacy
Trials

Long-term strip trials to evaluate the impact of cover crops and tillage on soil health. Currently looking to expand to more sites around the state.

Action
Trials

Flexible, replicated trials addressing relevant agronomic issues to provide actionable guidance on topics ranging from pest management to planting rates. They report findings and actionable guidance as soon as possible.

Demonstration
Trials

Less intensive trials, providing qualitative insights that provide an opportunity to highlight new products or practices.
