SARE Cover Crops Powerpoint

  1. 2. * Cover crop work starting in 1985, Univ. of MD * PhD (1993) on vetch/rye mixtures before corn - nitrogen and water * SARE outreach coordinator since 1995 [email_address] Andy Clark Corn no-tilled into hairy vetch
  2. 3. Grain / row crop farmers? Vegetable growers? Organic? other? Use cover crops? About you? Crimson clover
  3. 4. Grants and outreach to advance sustainable innovations to the whole of American agriculture. What is SARE? Red clover frost-seeded into wheat
  4. 5. SARE Grant Types Since 1988, SARE has invested in 4,000+ projects nationwide <ul><li>Farmer/Rancher </li></ul><ul><li>Research & Education </li></ul><ul><li>Professional Development </li></ul><ul><li>Graduate Student </li></ul><ul><li>Youth and Youth Educator (NCR) </li></ul>Go to for your region’s contact information.

  18. 19. Top Regional Cover Crop Species
  19. 20. Performance and Roles
  20. 21. Potential Disadvantages
  21. 22. Talk to local experts – farmers, educators Lots of Ohio literature! Read cover crop chapters in Managing Cover Crops Profitably Midwest CC Council ( Selecting a Cover Crop
  22. 23. <ul><li>See OSU Fact Sheet SAG-5-08 </li></ul><ul><li>Scavenges lots of N (planted early) </li></ul><ul><li>Biofumigation: suppresses weeds, disease and nematodes - tentative </li></ul><ul><li>Alleviates compaction (plow layer) </li></ul><ul><li>Large amount of biomass </li></ul>Oilseed Radish Oilseed radish
  23. 24. <ul><li>Needs 60 days frost-free </li></ul><ul><li>Plant after small grain, vegetable, corn silage, sweet corn, early soybean </li></ul><ul><li>N scavenging may improve with small N application at planting </li></ul><ul><ul><li>Very dependent on conditions </li></ul></ul><ul><li>Winterkills </li></ul><ul><li>Great, mellow seedbed </li></ul>Oilseed Radish Winter-killed oilseed radish
  24. 25. <ul><ul><li>Where’s the Nitrogen? </li></ul></ul><ul><ul><li>Jury is still out on this. Hundreds of pounds of N before winterkill, but much of the residue is gone in spring. </li></ul></ul><ul><ul><li>Winter/spring is the leaching season. </li></ul></ul><ul><ul><li>Is the residue breaking down (freeze/thaw) and N moving through the soil – using root channels? </li></ul></ul>Oilseed Radish
  25. 26. Maryland (unpublished) research: radish breaks plow pan better than rye (winter) New York research: Sorghum-sudangrass great at alleviating compaction (summer) Cover Crops and Compaction Oilseed radish Cereal rye
  26. 27. Rich Bennett, Napoleon, OH No-till RoundupReady beans into rye. See p. 104 Eric and Anne Nordell Trout Run, PA Sweetclover, buckwheat, vetch/rye for weed control in vegetables. See. p. 38 Farmer Cover Crops Profiles
