The Corn Belt Windbreak Project is a new initiative aimed at reviving windbreaks—rows of trees and shrubs that shield farms from extreme weather—across Illinois.
This blog post summarizes how researchers and farmers are collaborating to evaluate windbreaks planted through the Conservation Reserve Program (CRP), assess their economic viability, and quantify environmental benefits now and in the years ahead.
Reviving windbreaks in the Illinois Corn Belt
Windbreaks help protect soil from erosion, shelter crops from drying winds, and support wildlife.
In bare-soil seasons—such as spring and winter—their impact can be dramatic.
The project will study existing windbreaks, including stands dating back to the 1980s that were planted under the CRP, to learn how they perform across modern farming systems.
With many Illinois growers removing windbreaks to squeeze out a few extra rows of cash crops, understanding true profitability is critical.
Dallas Glazik, an Illinois farmer and conservation specialist with Pheasants Forever and Quail Forever, notes that cutting windbreaks may boost short-term crop counts but can lower long-term profitability and resilience.
He emphasizes windbreaks’ value for protecting soil and crops during rough seasons.
Project scope and partners
The initiative is led by the Savanna Institute, which received a five-year, $1.7 million USDA grant to study windbreaks in Illinois and Iowa.
The team will partner with dozens of farmers across target regions and work with the University of Illinois to integrate findings.
Nate Lawrence, an ecosystem scientist with the Savanna Institute, says researchers will examine windbreak impacts on soil health, wildlife habitat, crop yields, and water quality, to build a practical knowledge base for growers.
Economic and environmental value of windbreaks
Experts note the direct and indirect benefits of windbreaks extend beyond crop protection.
Windbreaks can reduce soil erosion by up to 95% during fragile seasons, helping maintain productive topsoil and reduce sediment loss downstream.
They also boost wildlife habitat and provide physical protection for neighboring farmland, creating a more resilient agricultural landscape.
Research questions and expected outcomes
By combining field measurements with farm-level data, the study will identify where windbreaks offer the greatest return on investment and how best to deploy end-row plantings and adjacent crop strips.
The collaboration with the Savanna Institute and the University of Illinois aims to translate technical results into practical recommendations for Illinois and Iowa producers.
What this means for farmers today
For growers currently evaluating windbreaks, the project promises actionable guidance on when and where windbreaks add value, especially in relation to end-row cropping.
The research will provide data-driven strategies to maintain windbreaks without sacrificing productivity, supporting a transition toward more climate-resilient farms.
Key benefits at a glance
- Soil protection: Windbreaks reduce erosion during bare-soil periods. This helps maintain soil health.
- Wildlife habitat: Shelter and forage boost biodiversity. This supports wildlife on working landscapes.
- Farm protection: Windbreaks shield adjacent fields from wind damage. They also help prevent drift.
- Economic potential: Strategic placement can improve long-term profitability. Windbreaks also enhance resilience.
With funding secured and farmers engaged, the Corn Belt Windbreak Project aims to translate research into practical, on-farm practices. These efforts benefit Illinois, Iowa, and their communities for years to come.
