December 16, 2010. Online. ATTRA - National Sustainable Agriculture Information Service will host a free one-hour webinar. This webinar will address how multi-species cover crops can be used to improve soil health, increase biological diversity, and benefit the bottom line in no-till grain operations. Jay Fuhrer, District Conservationist with the National Resource Conservation Service (NRCS) in Bismarck, North Dakota, will present four on-farm case studies to illustrate how to successfully use cover crop “cocktails” to enhance crop production and livestock forage in a no-till grain operation.
