Here are 10 great reasons to use Sulf-N ammonium sulfate:

  1. Honeywell is the world’s largest single-site producer of ammonium sulfate, and a global leader in agronomic research and promotion of this product
  2. University-proven across a broad geography of field and crop conditions
  3. Contains 21% nitrogen and 24% sulfur
  4. High analysis product; 900 pounds of plant nutrients per ton
  5. Nitrogen in the ammonium form means minimal susceptibility to losses from leaching, denitrification and volatilization
  6. Sulfur in the sulfate form means immediate nutrient availability for plant uptake
  7. Helps increase quality crop yields and overall farmer profitability
  8. Non-oxidizer means fewer restrictions on transportation and storage
  9. Less product shrink in storage due to higher critical relative humidity than ammonium nitrate and urea
  10. Can be blended with urea or ammonium nitrate and other fertilizer materials like DAP, MAP and MOP
