Study shows farmer led demonstration networks increase cover crop adoption
Cover crops play an important role in helping farmers improve soil health, protect water quality, reduce nutrient loss, and lower greenhouse gas emissions. However, only a small share of U.S. farmland currently uses cover crops, even with federal programs offering payments and incentives to encourage adoption.
A new study from the University of Illinois Urbana-Champaign shows that farmer demonstration networks may be an effective way to close this gap. Researchers found that a demonstration program in eastern Wisconsin led to a 50 percent increase in cover crop adoption over four years. This growth was supported by peer learning, local leadership, and stronger community awareness.
“Farmers may have an interest in trying new practices, but there’s a steep learning curve and high costs involved. Programs like this, where farmer leaders adopt practices that can be seen and communicated throughout a region, can really inspire their neighbors to take action,” said study co-author Marin Skidmore, assistant professor in the Department of Agricultural and Consumer Economics, part of the College of Agricultural, Consumer and Environmental Sciences at Illinois.
According to the study, farmers often want to try new practices, but they face challenges such as high costs, uncertainty, and a steep learning curve. Demonstration farms, where experienced producers test and showcase cover crops, help reduce these barriers. Farmers in nearby areas can see the results in real fields, ask questions, and attend field days. This practical, neighbor-to-neighbor support encourages confidence and encourages action.
