Final Report for LNC09-313
The Iowa and Minnesota Farmer Field School project focused on increasing cover crop adoption has now completed all grant deliverables. Our unique strategy, farmer field schools, allowed farmers and key participants to disseminate cover crop information with hands-on experience and practice via the demonstration acres, field days, and workshops to increase the adoption of cover crops in the Iowa and Minnesota landscape.
Research indicates multiple benefits from the use of cover crops with annual cropping systems. These benefits are diverse and help farmers transition to a more sustainable cropping system. The key benefits are:
? Cover crops sustain and improve the natural resource base system on which agriculture depends
? Cover crops significantly reduced nitrate leaching to subsurface drainage.
? Cover crops improve profitability by improving soil health, improve nutrient cycling, reduce soil erosion during critical times and enhance upland water storage.
? Cover crops provide harvest flexibility including soil cover, grazing, biomass, harvest and grain harvest. Cover crops provide important protection for groundwater recharge and source water protection.
This project was initiated because although a wealth of information for cover crops exists, farmers have not adopted cover crops as a management tool on a broad scale due to timing constraints in the fall following harvest, inadequate financial incentives for farmers, and lack of a strategic outreach plan to resource people and farmers. By the end of this project farmers reported significantly better understanding of cover crops plus converted that knowledge into added acres of cover crops in the IA and MN landscapes.
Long-term outcomes or systemic changes, which take longer to measure than the duration of this proposed project, would be improved water quality, reduced nitrogen use, and longer crop rotations from the addition of cover crops. Our project was initiated to increase adoption of cover crops which are a useful management tool for enhancing sustainability; reducing negative environmental impacts of annual cropping practices and support transition toward more sustainable perennial based cropping systems. To move toward this long-term outcome several short-term and intermediate outcomes have been accomplished.
Intermediate outcomes included increased practical experience with cover crops, increased and sustained usage of cover crops, and an improved CCDT resulting in increased usage. To measure these outcomes we have worked with several target audience participants to gather baseline information and post-project information. First, because the National Agriculture Statistical Survey or any other census body at the state or federal level does not collect data on cover crop acres in the state of Iowa and Minnesota we estimated acreage in 2009. To estimate acreage we worked with multiple organizations in both Iowa and Minnesota to acquire cover crop acreage. Between winter 2009 and spring 2010 farmers attending or within networks of these organizations were surveyed about their use of cover crops: at farmer meetings such as Pesticide Applicator Training workshops, the offices of Natural Resources Conservation Service [NRCS] and Farm Services Agency [FSA], local Soil and Water Conservation Districts [SWCD], workshops at commodity group meetings and extension. The same survey was given to farmers at the end of the project in fall 2012. Additionally, PFI members and farmers in the RA network received an end of project survey. Survey questions included: number of acres planted to cover crops during the project period; change in use either by adopting the practice, increasing acres planted or trying new species; and finally inquiry about resources used to increase cover crop knowledge to verify use of CCDT. Finally, at the end of the project we surveyed farmers who were in on-farm trials with PFI and RA. They were asked to identify if an increase in cover crop acres had spread to their neighbors within a 10-mile radius around their farm. Cooperators were asked to report how many new acres of cover crops existed each winter of the project in the 10 mile radius around their farm and how many farmers they networked with about using cover crops.
Short-term outcomes from this project was to increase awareness and knowledge of key information about cover crops to our target audience who consisted of but were not limited to: farmers, crop consultants and representatives of NRCS, Iowa and Minnesota Depts of Agriculture, FSA, SWCD, watershed associations, university extension and field agronomists and industry groups like Soybean Association, Corn Growers and water works staff. We provided farmer leaders opportunities to improve teaching and presentation skills. In addition, we increased interaction between resource people like extension or agency representatives and farmers where farmers were in charge of disseminating information to the resource community. These outcomes were measured by number of attendees at field days, type of attendee (i.e. farmer versus resource representative) and evaluation surveys sent via email or mailed to field day attendees and listening session participants.
Sample questions on the evaluation survey included:
• How effectively was the information presented?
• How useful was the information presented?
• What was your knowledge level prior to the meeting? After?
• Are you considering changing any farming practices as a result of the information received at this field day? OR Are you considering encouraging farmers to plant cover crops as a result of the information received?
• Overall, did the field day exceed, fall short, or meet you expectations?
Practical Farmers of Iowa (PFI) and Rural Advantage (RA) launched this project to increase the 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. However, a lack of converting understanding into action was prevalent at the start of this grant. This project not only disseminated information to farmers and key participants through farmer field schools with hands on experience and practice with cover crops, field days and workshops, but also incorporated farmers’ wealth of on-farm knowledge into the Midwest Cover Crop Council’s (MCCC) Cover Crop Decision-making Tool (CCDT). This tool provides information for farmers in the entire NCR-SARE area and is now available for Iowa and Minnesota. PFI and RA staff worked with cover crop working group teams in Iowa and Minnesota to incorporate our state specific information into the MCCC’s tool, which helps farmers choose a cover crop for their farm more precisely. As we are concluding our three-year project, we collected evaluations 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 has given farmers the opportunity to be leaders in disseminating this information to others and relies on a proven, unique method of learning through farmer-to-farmer networking.
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. 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. In 2011, we followed up with pilots that we listed in our Cover Crop Directory to find out how many acres of cover crops they planted in Iowa in the fall 2011. Seven aerial applicators said they planted approximately 19,000 acres.
We have conducted a cover crops survey in 2010 and in 2012. In 2010, we conducted surveys at three different field days hosted by Iowa State University Extension, Practical Farmers of Iowa, Iowa Soybean Association, The Nature Conservancy and NRCS on July 29, August 19, and September 14, 2010. The total number of respondents was 129. In 2012, we sent the surveys out to those who have attended our cover crops related events (field days, conference sessions, etc.) in the last three years. The total number of respondents was 185.
While the respondents of this anonymous survey were not exactly the same at two different times when we conducted the survey, target respondents are demographically similar, as they all attended the cover crops related events in Iowa and/or in Minnesota during the past three years.
The first question on the survey asked whether they have planted cover crops in the last five years (in 2010) or since 2009 (in 2012). While only 28.9% of the respondents answered yes in 2010, 53.2% of the respondents answered yes to this question in 2012.
The knowledge dissemination on cover crops seems to have occurred as well. In 2010, 33.7% of the respondents agreed or strongly agreed with the statement, “I don’t know enough about cover crops to use them.” In 2012, the number decreased to 10.2%. Similarly, while 26.1% of the respondents agreed or strongly agreed to the sentence, “the extra cost and possible yield reduction prevents my use of cover crops,” that number decreased to 13.2% in 2012.
While the knowledge about cover crops in general has improved, people still seem to be interested in learning more about specific resources for planting cover crops. Positive responses to the statements such as “I would like to learn more about aerial-seeding cover crops,” “I would like to know where to purchase cover crop seed,” I would like to know about local businesses that could plant or spring kill my cover crop” remained high in 2012 at 40% to 68%, which proves that the Cover Crops Business Directory that we created in 2010 remains to be a good information tool to hand out at our future cover crop related events.
PFI has published four research reports, titled “Winter Rye Cover Crop Effect on Cash Crop Yields” during this grant period, which discuss the economic impact of planting cover crops by comparing the yields of cash crops. In summary, farmers reported that when properly-managed, cover crops can be added to crop farms with little or no effect on yield of cash crops, whether it be corn, soybeans or corn silage. A full economic analysis was not part of the deliverables of this grant but were
At the end of this project, farmers who had conducted on-farm research projects were surveyed to estimate impact on their immediate neighbors. In Minnesota, three cooperators estimated they shared cover crop results with between 4 and 10 farmer neighbors. Five people estimated 11 to 20, two persons estimated 20, one person estimated 30, two people estimated 50, and finally one person estimated 200. Two people did not provide the estimated number, but they indicated they talked about cover crops with other producers all the time. In terms of the estimated cover crop acres within 10 miles, eight respondents said zero acres, five left the question unanswered, two said they didn't know, one estimated 15 acres, two estimated 100 acres, and one estimated 250 acres. One person said "usually about 100 acres, but in 2012 there were about 1,000 acres due to the drought/emergency EQIP sign-up” and one responded “about three other farms”, but did not specify the number of acres.
Two of the Iowa cooperators said they talked to between two and eight people. Two people said they discussed cover crops with about 50 people, and four people estimated 20-30. However, one of the four who estimated 20-30 people mentioned that he also spoke about cover crops at some state presentations where about 400 people were in attendance. Another respondent who also estimated 20-30 discussions about cover crops has been interviewed on the local radio frequently. His impact has reached thousands of farmers in his local area. In terms of the number of acres, our 11 respondents estimated the following cover crop acres within 10 miles from their farms respectively: 10, 20, 30, 100, 100, 160, 350, 1,000, 1,000-1,500, 3,000 and 3,500.

Areas needing additional study
Continued study of other cover crop species plus various planting methods is still needed in Minnesota and Iowa. Refining current cover crop recommendations to better suit the Iowa-Minnesota climate and cropping system is still needed. Great progress was made with this grant to improve the practical information available for farmers about cover crops but we still need to continue testing new cover cropping strategies. Specifically research focused on the management of cover crops in corn/soybean systems in MN, including timing of planting and species that work best. In recent years, we have been able to get corn in early, leading to a lot of corn acres harvested before the beans. This may open the door to more adoption of cover crops at these sites following a mid-September corn harvest. In addition, for MN, there needs to be better documentation and promotion of the soil health benefits of cover crops in corn/soy systems. We are seeing widespread adoption of cover crops in the states south of MN. Because of the shorter growing season, and frozen ground in the winter, we need more research on successful methods for this climate. Other topics, which need additional studies, include; residual herbicide affects, retrofitting high-clearance vehicles (economically) for seeding of cover crops, success rates of different cover crops and VNS versus named varieties.
