Ammonium sulfate is a highly effective nitrogen fertilizer with high sulfur content. Used in growing the most common cereals, oilseeds, feed, and vegetable crops. It stimulates plant development, improves product quality, and reduces nitrate risks. Nitrogen is presented in the ammonium form, ideal for prolonged nutrition systems. It also accelerates crop residue decomposition and improves soil fertility.

Crystal Grade Ammonium Sulphate dissolves cleanly, making it perfect for liquid applications. It provides nitrogen in readily available ammonium form and sulfur in fast-acting sulfate form, proving cost-effective even in cool or wet conditions.

💡 Key Applications
