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.
Participate in 2025 Trials
Illinois Soybean Association (ISA) is seeking farmer cooperators for the 2025 growing season to participate in on-farm trials. ISA is coordinating research to evaluate the yield impact of soybean sulfur fertilization across different environments in Illinois. Additionally, ISA is partnering with Dr. Nick Seiter on a study examining the return on investment from insecticide seed treatments or foliar insecticide applications. Cooperators will compare their preferred insect control methods with untreated control plots.
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.
