Ammonium Sulphate (NH4)2SO4: The High-Performance Dual-Nutrient Solution
Ammonium Sulphate is a premium inorganic salt, widely recognized as one of the most effective and versatile fertilizers in modern agriculture. Containing 21% Ammoniacal Nitrogen and 24% Sulphate Sulfur, it provides a synergistic nutrient delivery system that ensures rapid plant uptake, improved soil health, and maximized crop yields.

2. Strategic Agricultural Advantages
Ammonium Sulphate is often preferred over urea in specific environments due to its unique chemical properties:
-
Immediate Sulfur Availability: Unlike elemental sulfur, the sulfur in our product is in Sulphate form which is immediately available for plant root absorption, crucial for protein synthesis and chlorophyll formation.
-
Low Volatilization: The ammoniacal nitrogen is less prone to “gassing off” (volatilization) compared to urea, ensuring more nitrogen remains in the soil even when surface-applied.
-
pH Management for Alkaline Soils: It acts as an acidifying agent, effectively lowering the pH of alkaline/calcareous soils. This “unlocks” fixed micronutrients like Zinc, Iron, and Phosphorus, making them accessible to the crop.
-
Ideal for Paddy & High-Value Crops: It is the “Gold Standard” for rice cultivation and sulfur-demanding crops such as oilseeds (canola), corn, tea, and vegetables.
3. Industrial Utility
Beyond agriculture, our high-purity Ammonium Sulphate is utilized as a critical chemical intermediate:
-
Water Treatment: Used as a coagulant to remove impurities in wastewater processing.
-
Flame Retardants: Acts as a chemical additive in fireproofing textiles and wood.
-
Tanning Industry: Used in the deliming process of high-quality leather manufacturing.
-
Biotechnology: Employed as a precipitating agent for protein purification.
4. Logistics & Quality Assurance
-
Anti-Caking Technology: Our granular product is treated with professional anti-caking agents to ensure it remains free-flowing during long-distance maritime transport and mechanical spreading.
-
Flexible Packaging: Available in 25kg, 50kg, and 1000kg (Jumbo) UV-stabilized PP/PE bags.
-
SGS/CCIC Inspection: We offer third-party quality verification on every shipment to guarantee the 21.0% Nitrogen threshold.
