Farmer field school approach to increasing cover crop adoption in Iowa and Minnesota
This project will increase adoption of cover crops and support the transition toward more continuous living cover in the Iowa and Minnesota landscape. Cover crops are a useful management tool for enhancing the sustainability of annual cropping systems. A wealth of information exists about the benefits, challenges and production recommendations for using cover crops, and with a newly developed decision-making tool farmers now can more precisely choose a cover crop for their farm. But even with this knowledge lack of adoption is still prevalent. This project not only disseminates information to farmers and key participants through farmer field schools with hands on experience and practice with the crop, field days and workshops to tell neighbors about cover crops, but also incorporates farmers’ wealth of on-farm knowledge into a decision-making tool, which provides information for farmers in the entire NCR-SARE area. This work will be evaluated through feedback surveys, number of attendees, number of farmer inquiries about cover crops, increased number of acres and increased awareness and knowledge of cover crops by key audience participants. This campaign will give farmers the opportunity to be leaders in disseminating this information to others and relies on a proven method of learning through farmer-to-farmer networking.

Impacts and Contributions/Outcomes
Increased Momentum for Cover Crops
Again, planting cover crops has been documented to be an immediate, practical method to improve water quality and decrease Iowa and Minnesota’s effect on the size of the Gulf Hypoxic Zone. Practical Farmers of Iowa and Rural Advantage have been recognized as important resources and leaders for cover crops information. PFI has also provided information to farmers about funding available through the Environmental Quality Incentives Program (EQIP) provided by NRCS as well as state cost-share. In 2011, PFI worked with county commissioners to pass a resolution to provide cost share to farmers from the State Cost Share fund. In 2012, 117 farmers took advantage of these cost share funds. Seed houses that sell cover crop seed have said there was a shortage of winter small grains available because of the increased demand for cover crops in Iowa in 2012. In the fall of 2012 there was a waiting list at several seed houses for farmers to buy cover crop seed. We need to continue pulling the pieces together to meet this demand and encouraging greater use of the practice.
