Ammonium Sulfate (AS) – Nitrogen & Sulfur Fertilizer | 21% Nitrogen, 24% Sulfur | Granular / Powder | Agricultural & Industrial Grade

DESCRIPTION:

Ammonium Sulfate (AS) is a widely-used nitrogen and sulfur fertilizer containing 21% nitrogen (N) and 24% sulfur (S)—two essential nutrients for crop performance. Its ammonium form of nitrogen promotes strong root development and reduces nutrient losses through leaching. The high sulfur content enhances protein synthesis, oil formation, and enzyme activity, making AS especially important for cereals, legumes, oilseeds, and vegetables.

Available in granular and powder formats, the product offers flexibility for direct soil application, fertigation, blending with NPK formulations, and industrial nutrient solutions. Granules provide excellent spreadability and low dust levels, while powder dissolves easily for liquid fertilizer production.

Ammonium Sulfate is valued for its chemical stability, low hygroscopicity, compatibility with most fertilizers, and consistent performance across various soil types. It is ideal for buyers seeking reliable, long-term sourcing from verified global producers.

This listing targets importers, wholesalers, agro-projects, plantations, blending plants, and industrial processors.
