21-0-0-24S Crystalline Ammonium Sulfate
(NH₄)₂SO₄ — ammonium sulfate
MKT ammonium sulfate is a crystalline fertiliser containing 21% ammonium nitrogen and about 24% sulfur. Its good solubility, even sugar-like crystals and acidifying reaction in soil make it suitable for direct use and compound-fertiliser production.

Buyer Questions
Questions buyers ask about MKT ammonium sulfate
How much nitrogen is shown in the available analysis?
The typical analysis is 21% ammonium nitrogen, about 24% sulfur and less than 0.5% moisture.
Which soils benefit most from ammonium sulfate?
It is particularly useful in calcareous and alkaline soils because it supplies nitrogen and sulfur while creating an acidifying reaction around the root zone.
Is the product crystalline or granular?
MKT’s main product is crystalline, or sugar-form, ammonium sulfate suitable for direct application, dissolution and blending with other fertilisers.
