AS (Ammonium Sulfate)

AS is a granular ammonium sulfate fertilizer supplying 21% ammonium nitrogen and 24% sulfate sulfur in a single straight product. The ammonium form resists leaching and feeds crops gradually, while the readily available sulfate sulfur supports protein synthesis, chlorophyll formation and nitrogen uptake. Suited to universal field use across cereals, oilseed rape, maize, sugar beet, potatoes and vegetables, it is broadcast or incorporated into soil before sowing, or applied as an early-season top dressing where crops show high nitrogen and sulfur demand.
