    SARE Cover Crops Powerpoint SARE Cover Crops Powerpoint Presentation Transcript

    • * 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
    • Grain / row crop farmers? Vegetable growers? Organic? other? Use cover crops? About you? Crimson clover
    • Grants and outreach to advance sustainable innovations to the whole of American agriculture. What is SARE? Red clover frost-seeded into wheat

        • Up to $10,000 for individual producer
        • Up to $15,000 for producer organization
        • Due 12/3/2009
      Producer Grants
    • 20 Years of Impact 79 percent of producers said they improved soil quality through their SARE project 64 percent of producers said their SARE project helped them achieve higher sales 75 percent of educators surveyed led at least one program to share innovations Photo courtesy Karl Kupers
    • SARE Outreach a library of practical, how-to books (in print or download for free) media outreach a portfolio of in-depth reports on current topics conference sponsorships countless online resources, including project reports
    • SARE’s 3rd edition of
      • Farmer and research results & experiences
      • How-to information
      • Scientific background
      • Specific cover crops
      • Available online
      • How to use book (p. 7)
      • Benefits of cc (p. 9)
      • Selecting cc (p. 12)
      • Building soil fertility
      • Managing pests
      • Crop rotations
      • Conservation tillage
      • CHARTS (p. 62)
      • Cover crop chapters
      Managing Cover Crops Profitably Cereal Rye
      • Soil : erosion, organic matter, soil moisture
      • Nutrients : add or scavenge
      • Manage weeds & pests
      Benefits of Cover Crops Ryegrass overseeded into kale
      • More time / management
      • Spring / fall workload
      • Weed potential
      • Harbor pests
      • Soil moisture use
      • How to kill / timing of kill
      Cover Crop Drawbacks Rye & Vetch in Tomatoes
      • Winter vs. summer
      • Legume vs. non-legume
      • Annual, biennial, perennial
      • Intercropped
      • Cover crop mixtures
      Types of Cover Crops
    • Non-legume Cover Crops Grasses, brassicas, mustards, buckwheat
      • Reduce erosion
      • Large amounts of residue
      • Add organic matter
      • Suppress weeds
      • Scavenge nutrients (N)
      • May immobilize N
      • Do NOT add N
      • See soil fertility chapter
      Cereal Rye
      • Annuals : hairy vetch,
      • field peas, cowpeas
      • Perennials : red & white clover,
      • medics, alfalfa
      • Biennials : sweetclovers
      • Fix nitrogen (N)
      • Reduce erosion
      • Less residue, shorter time
      • Less organic matter
      Legume Cover Crops Ryegrass overseeded into kale
      • Define problem or use
        • Add N; manage nutrients; reduce erosion; mulch
      • Identify niche in rotation
        • Winter vs. summer
        • Full season; short window
      • Labor and equipment needs!
      Selecting a Cover Crop No-till soybeans into rye
      • How will I seed the cc?
      • What’s the weather then?
      • How much biomass?
      • Will it winterkill?
      • How will I kill it?
      • How will I plant into it?
      • Do I have the time to do this?
      • What’s my contingency plan?
      Answer the Hard Questions
    • Top Regional Cover Crop Species
    • Performance and Roles
    • Potential Disadvantages
    • 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
      • See OSU Fact Sheet SAG-5-08
      • Scavenges lots of N (planted early)
      • Biofumigation: suppresses weeds, disease and nematodes - tentative
      • Alleviates compaction (plow layer)
      • Large amount of biomass
      Oilseed Radish Oilseed radish
      • Needs 60 days frost-free
      • Plant after small grain, vegetable, corn silage, sweet corn, early soybean
      • N scavenging may improve with small N application at planting
        • Very dependent on conditions
      • Winterkills
      • Great, mellow seedbed
      Oilseed Radish Winter-killed oilseed radish
        • Where’s the Nitrogen?
        • Jury is still out on this. Hundreds of pounds of N before winterkill, but much of the residue is gone in spring.
        • Winter/spring is the leaching season.
        • Is the residue breaking down (freeze/thaw) and N moving through the soil – using root channels?
      Oilseed Radish
    • 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
    • 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
