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