Ammonium Sulfate Fertilizer – 21% Nitrogen & 24% Sulfur

Boost crop nutrition and optimize soil health with Ammonium Sulfate Fertilizer, delivering 21% ammoniacal nitrogen and 24% plant-available sulfate sulfur. As a physiologically acidic fertilizer, it is particularly effective for amending alkaline and calcareous soils while supplying vital nutrients that enhance protein synthesis, chlorophyll formation, and overall plant vigor.

Guaranteed Specifications

• Total Nitrogen (N): ≥21.0% (Ammoniacal Nitrogen)
• Sulfur (S): ≥24.0% (Sulfate Sulfur)
• Moisture: ≤0.5%
• Appearance: White or translucent crystalline powder / compact granules

Grades & Application Methods

• Crystalline Grade: Rapid-dissolving with high water solubility. Highly recommended for drip irrigation, fertigation systems, foliar spraying, and liquid fertilizer formulation.
• Granular Grade: Durable, low-dust granules engineered for uniform mechanical broadcast spreading, direct soil application, and bulk blending (BB fertilizer).

Agronomic Benefits & Target Crops

• Alkaline Soil Improvement: Helps lower rhizosphere pH in high-pH soils, improving the availability and uptake of phosphorus and micronutrients.
• High-Sulfur Nutrition: Ideal for sulfur-demanding crops including tea bushes, fruit trees, vegetables, oilseeds, and field cash crops.
• Fertilizer Manufacturing: Widely sourced by fertilizer blenders, water-soluble fertilizer manufacturers, and commercial orchard bases.

Storage & Handling Guidelines

Store in a cool, dry, and well-ventilated storage facility. Keep packaging tightly sealed to prevent moisture absorption and caking. Always consult local agronomic guidelines and test soil parameters before determining field application rates.
