Farmer field school approach to increasing cover crop adoption in Iowa and Minnesota
The project will increase adoption of cover crops and support the transition toward more continuous living cover. 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 we are developing a new decision-making tool for farmers when choosing a cover crop species. But even with this knowledge lack of adoption is prevalent. This project will not only disseminate 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 incorporate farmers’ wealth of on-farm knowledge into a decision-making tool which will provide 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.

• Linked Iowa groups and Iowa farmers interested in cover crops to the Midwest Cover Crops Council during Midwest Cover Crops Council meeting held March 2-4 in Ames, Iowa. Three members of Practical Farmers of Iowa (1,000-acre no-till conventional farm, a 600-acre organic grain and livestock operation, and a two-acre vegetable farm) presented on how they use cover crops in their operations.
• 27 cooperators have started and have been continuing research and demonstration on cover crops
1. 11 cooperators are testing cover crops’ effect on crop yield
2. Four cooperators are grazing cover crops
3. Two cooperators are testing new species of cover crops (tillage radish)
4. Five cooperators are aerial seeding cover crops
5. Two cooperators are overseeding cover crops, using our Hagie Highboy
6. Three cooperators are using cover crops in horticulture systems.
• Conducted cover crops surveys at three different field days hosted by Iowa State University Extension, Practical Farmers of Iowa, Iowa Soybean Association, Nature Conservancy and NRCS on July 29, August 19, and September 14, 2010. The total number of respondents was 129.
• Published five cover crop media stories and developed Cover Crop Business Directory which helps farmers to find seed houses in the Upper Midwest that sell cover crop seed, aerial applicators who can fly on the cover crop in the fall and custom sprayers who could kill the cover crop in the spring.

Impacts and Contributions/Outcomes
Increased Momentum for Cover Crops
In the past year, planting cover crops has emerged as one practical method of many solutions to improve water quality and potentially decrease the size of the Gulf Hypoxic Zone. PFI has been recognized as an important resource and leader in cover crops information. After release of the Mississippi River Basin Initiative (MRBI), which listed cover crops as one of the top 3 practices for improving water quality PFI has been contacted by Iowa NRCS state and county staff to provide information and presentations about cover crops. PFI has also provided information to farmers about funding available through the Environmental Quality Incentives Program (EQIP) provided by NRCS which offers a cost share at $45/A for non-over wintering and $60/A for over-wintering cover crops. In addition to federal policy, local groups like the Iowa Soybean Association, Iowa Department of Agriculture and Land Stewardship and several NRCS county offices have held meetings and initiated cover crop on-farm research projects. PFI has worked with these groups to know more about the ways in which cover crops can be mainstreamed.
