Advancing Cover Crop Adoptions Research Agenda

Will corn planted after cover crops consistently out-yield corn planted without cover crops? Research has shown some nice advantage in areas. More research should give farmers more confidence in cover cropping.

Sarah Carlson, Midwest Cover Crop Research Coordinator with  Practical Farmers of Iowa and Ryan Stockwell, Agriculture Program
Manager with the National Wildlife Federation have written an agenda that will help researching cover crops be more scientific over the next six to eight years.   The research agenda is published in the Journal of Agriculture, Food Systems, and Community Development

Abstract
Given certain ecologic and agronomic characteristics of conventional corn and soybean monocultures, cropping systems reliant solely on these two commodities inevitably lose soil and nutrients.  Leaky cropping systems not only hamper society with negative externalities, but also erode the very natural resources needed to produce food and sustain civilization. The United States Department of Agriculture (USDA), state agriculture department staff, farmer organizations, agribusiness leaders, and conservation and environmental organizations now see cover crops as a solution to reduce the negative externalities of conventional row-crop agriculture. Farmers are asking for increased agronomic and economic research to help them understand the benefits of and implement the use of cover crops. Researchers for the most part are not keeping up with farmers’ innovations on cover crops nor on providing the information sought by farmers. This article outlines the questions farmers are asking about cover crops and provides suggestions to agronomists, soil scientists, and researchers on research topics to best answer those questions. Additionally, social scientists must initiate a new round of research to understand the underlying concerns farmers have with cover crops and help to define the information (both content and source) that best informs and influences farmers. This article outlines specific issues and questions social scientists can research to contribute to the advancement of more sustainable farming practices and, in particular, cover crops.

Results of Farmer Cover Crop Survey Conducted by SARE and CTIC

Folks,
If you want to see how cover crops provide a very good ROI across a wide geographic region then this report is for you!  Thanks to Rob Meyers from SARE and the folks at CTIC for conducting and publishing this survey.  It helps me to see that the results on our home farm (and many of your farms too) were duplicated over a broad area.

Cover crops REALLY help with yield :)
Cover crops REALLY help with increasing yield 🙂            (BTW, we are NOT really standing up.)
Here is Rob’s e-mail.  Check out the link to see the whole report.
We are releasing today the results of a farmer survey on cover crops that was conducted by SARE and the Conservation Technology Information Center (CTIC) this past winter.  A majority of the surveys were completed by farmers attending Midwest conferences this past winter but we also had some respondents to the online version of the survey from across the U.S.  The survey analysis and report development was completed by CTIC under a contract from North Central Region SARE.  Questions on the survey were developed with the input of MCCC steering committee members.  The report is available online at:  http://www.northcentralsare.org/CoverCropsSurvey
Key findings included the following:
  • During the fall of 2012, corn planted after cover crops had a 9.6% increase in yield compared to side-by-side fields with no cover crops.  Likewise, soybean yields were improved 11.6% following cover crops.
  • In the hardest hit drought areas of the Corn Belt, yield differences were even larger, with an 11.0% yield increase for corn and a 14.3% increase for soybeans.
  • Surveyed farmers are rapidly increasing acreage of cover crops used, with an average of 303 acres of cover crops per farm planted in 2012 and farmers intending to plant an average of 421 acres of cover crops in 2013.  Total acreage of cover crops among farmers surveyed increased 350% from 2008 to 2012.
  • Farmers identified improved soil health as a key overall benefit from cover crops.  Reduction in soil compaction, improved nutrient management, and reduced soil erosion were other key benefits cited for cover crops.  As one of the surveyed farmers commented, “Cover crops are just part of a systems approach that builds a healthy soil, higher yields, and cleaner water.”
  • Farmers are willing to pay an average (median) amount of $25 per acre for cover crop seed and an additional $15 per acre for establishment costs (either for their own cost of planting or to hire a contractor to do the seeding of the cover crop).
Please help us distribute this information to your colleagues and farmers in your region.
