7. Acidifying or Neutralizing Effects of Nitrogen Sources

8. Attributes of Nitrate Nitrogen Prevent acid soils and low pH Prevent acid soils and low pH Reduce chance of Nitrate loading of plants Reduce chance of Nitrate loading of plants  Reduces green cure  Reduces fat stems  Which can freeze and bleed onto leaf  Which can lead to high moisture reading at market

9. Rank Green Tobacco at Harvest

10. Fat Stem Cause Poor Curing
