Ammonium Sulfate
Nitrogen and sulfur together, with no volatilization loss.
Ammonium sulfate supplies 21% nitrogen and 24% sulfur in a single granular product, and unlike urea it does not volatilize when surface-applied — the nitrogen you spread is the nitrogen the crop gets. Its mild acidifying effect also makes it a good fit for the calcareous, high-pH soils common across South Texas and Northern Mexico.

Principal Industrial Uses
Where it's used, and why.
Row Crop Agriculture
Nitrogen and sulfur source for cotton, corn, sorghum, and small grains — particularly valuable on high-pH calcareous soils where its acidifying effect improves nutrient availability.
Fertilizer Blending
Standard component in bulk-blended and compound fertilizer formulations where sulfur must accompany nitrogen.
Industrial & Drilling
Shale-inhibition additive in water-based drilling fluids, and a nitrogen source across a range of industrial processes.
