Main advantages
About this product
Ammonium sulfate is a straight nitrogen fertilizer manufactured to GOST 9097-82, delivering 21% nitrogen in readily available ammonium form together with 24% sulfur. The ammonium nitrogen resists leaching and acidifies the root zone, which suits alkaline soils, while the sulfur supports protein synthesis and oil formation. It is applied to the soil before or during sowing and is particularly valuable for cereals, oilseed rape, sugar beet and brassica crops that respond strongly to sulfur nutrition.
