Ammonium Sulfate 21-0-0

Ammonium Sulfate, 21-0-0, is an inorganic water-soluble salt that contains:

  • 21% Nitrogen.
  • 24% Sulfur.
  • 21-0-0.

Ammonium Sulfate's high nitrogen content is what makes it the perfect supplement for nitrogen deficient soils and lawns, alike. Since lawn grass requires nitrogen, commercial lawn fertilizer products use ammonium sulfate to stimulate quick growth of grass turf and healthy lawn grass.

Ammonium sulfate fertilizers easily blend with other nitrogen fertilizers allowing for a more stable, dry-lawn fertilizer. But you'll want to exercise greater caution when using Ammonium Sulfate fertilizers as they can elevate soil acidity to extreme levels that could adversely affect grass or crops.
