CAS 7783-20-2 (NH4) 2so4 Agricultural Fertilizer Bulk Granular Ammonium Sulfate

CAS 7783-20-2 (NH4) 2SO4 Agricultural Fertilizer Bulk Granular Ammonium Sulfate is a highly versatile bulk nitrogen-fertilizer raw material for agriculture. Featuring dual nitrogen-sulfur nutrients and well-formed granular appearance, it is suitable for large-volume bulk storage and transportation. Widely applied in diverse soils and crop cultivation, it releases nutrients steadily to boost crop growth, improve fruit quality and enhance crop stress resistance. It serves as an essential fertilizer for base fertilization, top-dressing and seed dressing in modern agriculture, well‑suited for large-scale agricultural-material trade and field production.

1. Key Product Features

CAS 7783-20-2 (NH4) 2SO4 Agricultural Fertilizer Bulk Granular Ammonium Sulfate has stable physicochemical properties with strictly controlled impurities. Its nitrogen content reaches 21.2%, complying with national standard GB/T 535-2020. With low moisture content and well-managed free acid index, the uniform dry granules resist caking, ideal for bulk delivery and mechanical spreading. It features good water-solubility; nutrients are released gradually in soil for continuous crop uptake. Classified as non-hazardous chemical, it allows convenient storage and transportation. It is available in 25kg and 50kg bags as well as bulk shipment. Free samples are supported. Batch-to-batch indicators remain stable to guarantee consistent fertilizing performance.

2. Scope of Application

CAS 7783-20-2 (NH4) 2SO4 Agricultural Fertilizer Bulk Granular Ammonium Sulfate fits most soil types and various crops. It can be used as base fertilizer, top-dressing and for seed dressing. It works for grain crops including wheat, corn and rice, as well as fruits, vegetables and cash crops. It supplies nitrogen and sulfur to foster robust plant growth, increase yield, improve fruit quality and strengthen crop disaster resistance. Besides direct field application, it can act as fundamental raw material for compound fertilizer manufacturing.

3. Usage and Storage Precautions

Apply proper dosage according to soil fertility and crop varieties to prevent fertilizer burn caused by excessive local concentration. Do not store or apply together with strong-alkaline fertilizers to avoid nitrogen volatilization loss. Store in dry, ventilated place, keep away from moisture and rain to prevent caking. Avoid over-high stacking to prevent package damage. Cover goods during transportation. Use up opened goods as soon as possible and seal residual materials. Though non-hazardous, avoid inhaling excessive dust during operation.
