  1. Utilizing Late Season Cover Crops In A No-Till Environment Dan Forgey Gettysburg, SD

  2. A Special Thanks To USDA-ARS (Dr. Shannon Osborne) Dakota Lakes ( Dr. Dwayne Beck) SDSU Extension (Ruth Beck - Terry Hall) NRCS (Jason Miller)

  3. Incorporating cover crops to increase soil quality

  4. Benefits of Organic Matter Nutrient Supply 1. Each percent of organic matter releases 20 to 30 pounds of nitrogen 4.5 to 6 pounds phosphorus 2 to 3 pounds sulfur Managing Cover Crops Profitably Third Edition

  5. 2. Water Holding Capacity Organic matter act like a sponge. It will hold up to 90% of its weight in water. 3. Soil Structure Aggregation Organic matter causes soil to form aggregates which helps with water infiltration. 4. Erosion Prevention Increasing soil organic matter from 1 to 3 percent can reduce Erosion by 20 to 30 percent because of water infiltration.

  6. Average Rainfall 18.5 inches rain

  7. Cover Crops Used 57 Acres 1.Lentils 2.Canola 3.Cowpea 4.Canola/Lentils 5.Canola/Cowpea 6.Canola/Cowpea/Lentils 6.Radish/Cowpea/Lentils 7.Turnip/Cowpea/Lentils 8. No cover crop X 3

  8. Methods Rotation Winter Wheat – Cover Crop - Corn 1. Fall Soil Samples (Aug and Oct) 2. Cover Crop Growth 3. Preplant Spring Soil Samples 4. Corn Biomass V6 and Soil Samples 5. Corn Biomass R1 and Soil Samples 6. Corn Grain Yield and Protien

  9. Planting Cover Crops What will the neighbors think ?

  10. We soil sampled four times

  11. This was the fun part watching them grow.

  12. Letting everyone know our seed cost.

  13. This is the future. Gettysburg FFA on a field day.

  14. Great turn out at our field day.

  15. This is what it is all about.

  16. This is as good as it gets.
