For years, Dr. Joel Gruver of Western Illinois University has been putting out extremely informative and well-done presentations on SlideShare. Dr. Gruver is the cover crop authority in Illinois. While not at a land-grant institution, he is the primary researcher invited to speak to cover crop meetings in this region. While we at Ask the Plant do not know him personally, we continue to find his work interesting and applicable to many growers outside of Illinois. Be sure to check out all of his diverse presentations under “Presentations” on the right side of the web page.
