$ 8.99

Ammonium Sulfate is a chemical compound crystalline in nature used primarily in the manufacture of artificial alkaline soil fertilizers for agriculture and in printed circuit boards' production. This compound is an inorganic water soluble salt that contains 21% Nitrogen and 24% Sulfur.


It is a water soluble fertilizer that has been extensively used for crop production owing to the fact that it provides efficient nitrogen and readily-available sulfur which aids in plant growth. Ammonium Sulfate fertilizer is widely used as a soil supplement, and it has become paramount in the maintenance of healthy soil and vibrant crop growth by adding general value to alkaline soils.


Ammonium Sulfate is an affordable Nitrogen fertilizer widely used as a lawn fertilizer. Since lawn grass requires nitrogen, commercial lawn fertilizer products use ammonium sulfate that contains nutrients that stimulate the quick growth of grass turf.


Ammonium sulfate fertilizers easily blend with other nitrogen fertilizers for a more stable dry lawn fertilizer. Also, it improves and eases gardening by promoting healthy growth of lawn grass. Ammonium Sulfate Fertilizers should be used with more caution since they can elevate soil acidity to extreme levels that could adversely affect grass or crops.
