Maxing Ammonium Sulfate for East Africa: Product Overview and Supply

Ammonium sulfate is the only common fertilizer that delivers both nitrogen and sulphur in a single product. With sulphur deficiency affecting over 60 % of East African cropland, ammonium sulfate addresses two nutrient gaps with one application. Maxing supplies high-quality ammonium sulfate from Qingdao for the East African market.

Why Ammonium Sulfate for East Africa

East African soils are increasingly sulphur-deficient as farmers shifted from single superphosphate (which contained sulphur) to DAP (which does not). Ammonium sulfate restores the sulphur balance while providing nitrogen — a two-in-one solution.

Compared to urea, ammonium sulfate has lower volatilization losses, making it safer to apply in hot, dry conditions. It is also the preferred nitrogen source for sulphur-loving crops like coffee, tea, and oilseeds.

FAQ

Q: Is Maxing ammonium sulfate granular or crystal?

A: We supply both forms. Granular (2-4 mm) is better for mechanical spreading and blending. Crystal (1-3 mm) is suitable for manual spreading and dissolves faster. Specify your preference when ordering.

Q: Can ammonium sulfate be blended with DAP?

A: Yes, ammonium sulfate and DAP are compatible for blending. The combination provides nitrogen, phosphorus, and sulphur. However, store blended product in dry conditions as the mix can absorb moisture.

Q: What is the shelf life of ammonium sulfate?

A: When stored in dry conditions on pallets in a covered warehouse, ammonium sulfate has an indefinite shelf life. In humid tropical conditions, use within 12-18 months to prevent caking.
