Ammonium sulphate (SOA AS) is an inorganic salt with multiple commercial applications. Its primary use is as a quick-release fertilizer for alkaline soils, offering fast-acting nitrogen and sulfur nutrients. This product is hygroscopic and may cake, making it ideal for direct application as seed fertilizer, base dressing, or topdressing. Particularly effective for sulfur-deficient soils and crops with low chlorine tolerance, including rice seedlings, tea plants, grasses, and vegetables.
