Transcript

  • 1. Nitrogen
    • Everything you need to know and a little more!!!
  • 2. Where does Nitrogen Come From?
  • 3. Nitrogen Sources
    • Atmospheric
    • Biological
    • Industrial
  • 4. Atmospheric
    • 78% of the Air We Breath is Nitrogen (N 2 )
  • 5. Biological (Bacteria) There are two types of “ Nitrogen Fixing Bacteria” Free Living Bacteria (“fixes” 30% of N 2 ) Symbiotic Relationship Bacteria (“fixes” 70% of N 2 )
  • 6. Symbiotic Relationship Bacteria live in the roots of legume plants and provide the plants with ammonia (NH 3 ) in exchange for the plant’s carbon and a protected home. Legume plants
    • Roots with nodules where bacteria live.
    • Atmospheric Nitrogen changes into ammonia.
    NH 3 N N
  • 7. Industrial
    • Common Nitrogen Types:
      • Anhydrous
      • Urea
      • Ammonium Sulfate
      • ESN
      • UAN
      • SuperU
  • 8. How do plants use Nitrogen?
    • Needs to be in the correct form for plants to update.
    • Plants can not use Atmospheric N
    • Needs to be Converted Before Plant can use it.
      • NH 4 or Ammonia
      • NO 3 or Nitrates
  • 9. Lets Look At the Nitrogen Cycle
  • 10. Industrial Nitrogen Applied
  • 11. How do they make Anhydrous?
  • 12. How it is used?
    • Anhydrous
      • Typically applied in the fall
      • Stable at 40 degrees soil temp.
      • Highest concentration of nitrogen
      • Used to make all other types of Nitrogen
      • Stored under high pressure
      • Is liquid when it is compressed or cooled
  • 13. How do they make UREA?
  • 14. How is it used?
    • Urea
      • Granular form 46-0-0 or 46% Nitrogen
      • Used in:
        • Starter Fertilizer
        • Sidedress Applications
      • Starts breaking down as soon as it makes contact with soil.
        • Can Volatile or Leach
      • Can add products like Agrotain
  • 15. What does Agrotain Do?
      • http://www.agrotain.com/agriculture/english/index.html?p_id=1d
  • 16. How do they make ESN?
    • Take Urea and put a Polymer Coating on it.
    • Reduces it from 46-0-0 to 44-0-0
  • 17. ESN
    • Coated Urea
    • Slow Release Fertilizer
  • 18. How is ESN used?
    • Typically it is applied pre-plant and incorporated.
    • Releases nitrogen for 30-60 days.
    • Eliminates the need to side-dress.
    • Does not release when it is dry and/or cold.
    • Helps to prevent Nitrogen losses from vitalization and/or leaching.
  • 19. SuperU (like having Agrotain already impregnated on the Urea)
  • 20. SuperU
    • SUPER U inhibits the conversion of urea to ammonium and ammonium to nitrate
    • Reduces losses:
      • Volatilization
      • Leaching
      • Denitrification
  • 21. How do they make UAN?
    • Forms: Liquid 28% or 32%
    • Can be blended in Starter or Side-dressed
    • Will burn the plant if applied post-emergent.
