Transcript

  • 1. <ul><li>By </li></ul><ul><li>Craig Askim/Extension Agent </li></ul><ul><li>Mercer County </li></ul>
  • 2. What is a cover crop?
  • 3. Does it really matter?
  • 4. Why do we have agriculture? How long will we need it? What does it take to raise crops and livestock?
  • 5. The North Dakota experience was difficult, expensive and unprofitable.
  • 6. Background Information <ul><li>Mercer County – Beulah, ND </li></ul><ul><ul><li>Located about 80 miles northwest of Bismarck, ND </li></ul></ul><ul><ul><li>Population, 8000 </li></ul></ul><ul><ul><li>455 farms </li></ul></ul><ul><ul><li>Average size 1,200 acres </li></ul></ul><ul><ul><li>37,000 head of cattle </li></ul></ul><ul><ul><li>Main farm income in county </li></ul></ul>
  • 7. Mercer County
  • 8. Selecting the Best Cover Crop <ul><li>What is the goal? </li></ul><ul><ul><li>Break weed and insect cycles </li></ul></ul><ul><ul><li>Planting sod crops </li></ul></ul><ul><ul><li>Reduce amount of fertilizer </li></ul></ul><ul><ul><li>Add organic matter </li></ul></ul><ul><ul><li>Improve soil structure </li></ul></ul><ul><ul><li>Reduce erosion </li></ul></ul><ul><ul><li>Remove excess water </li></ul></ul>
  • 9. Factors to Consider <ul><li>Yield stability </li></ul><ul><li>Economic return </li></ul><ul><li>Equipment availability </li></ul><ul><li>Registered pesticides and herbicides </li></ul><ul><li>Impact on crop rotation </li></ul><ul><li>Crop adaptation </li></ul>
  • 10. More Factors to Consider <ul><li>Timing /Long term plan </li></ul><ul><li>Current/Next year’s crop </li></ul><ul><li>Current weed pressures </li></ul><ul><li>Moisture conditions </li></ul><ul><li>Past pesticide seed crop rotation restrictions </li></ul>
  • 11. Pesticides of Concern <ul><li>Crops </li></ul><ul><ul><li>Wide –Match </li></ul></ul><ul><ul><li>Dicamba </li></ul></ul><ul><ul><li>Curtail </li></ul></ul><ul><ul><li>Huskie </li></ul></ul><ul><ul><li>Spartan </li></ul></ul><ul><li>CRP Breakout </li></ul><ul><ul><li>Tordon , Milestone, Plateau, Curtail </li></ul></ul>
  • 12. Purpose <ul><li>Encourage the use of a variety of alternative forages for grazing and feed such as turnips, hairy vetch, triticale, winter rye, oats, and peas. </li></ul><ul><li>Promote prescribed grazing systems and diversity in no-till cropping systems. </li></ul>
  • 13. Soil Armor <ul><li>Cover crops protect soil from damaging winds, water, and high temperatures. </li></ul>
  • 14. Soil Temperatures <ul><li>Soil bacteria die at 140° F. </li></ul><ul><li>100% of moisture is lost due to evaporation and transpiration at 130° F. </li></ul><ul><li>At 100° F. – 15% of the moisture is utilized for growth and 85% is lost to evaporation and transpiration </li></ul><ul><li>At 70° F. nearly 100% of the moisture is used for growth </li></ul>
  • 15. Total Benefits <ul><li>Decrease inputs – long term </li></ul><ul><li>Decrease weed competition </li></ul><ul><li>Provides second crop – haying or grazing </li></ul><ul><li>Increases soil health </li></ul><ul><li>Increases organic matter </li></ul>
  • 16. Adding Alternative Feed and Forage to FarmingRanching Operations <ul><li>Improve the native rangeland health and vigor by earlier removal of livestock </li></ul><ul><li>Maintain a stable and desired plant community </li></ul><ul><li>Enhance nutrient cycling through crop diversity </li></ul><ul><li>Improve animal health and productivity </li></ul><ul><li>Reduce soil erosion </li></ul><ul><li>Improve soil condition for sustainability of the resource </li></ul><ul><li>Increase soil organic matter </li></ul><ul><li>Improve ground water quality and infiltration </li></ul><ul><li>Minimize contained feeding duration </li></ul>
  • 17. Resource Concerns Being Addressed Locally <ul><li>Pasture grazing rotation </li></ul><ul><li>Erosion </li></ul><ul><li>Crop & hayland health </li></ul><ul><li>Noxious weeds </li></ul><ul><li>Ag waste </li></ul><ul><li>Water quality </li></ul><ul><li>Education </li></ul><ul><li>Wildlife habitat </li></ul><ul><li>Soil quality health </li></ul><ul><li>Wetland health </li></ul>
