Ammonium Sulfate Granules | High-Nitrogen High-Sulfur Compound Fertilizer | Granular Ammonium Sulfate Manufacturer Direct Sales
What Are Ammonium Sulfate Granules?
Ammonium Sulfate Granules, chemically known as ammonium sulfate, are a high-efficiency compound fertilizer primarily providing nitrogen and sulfur. Utilizing advanced granulation technology, the product transforms ammonium sulfate raw materials into uniform 2–4mm granules, offering benefits such as rapid dissolution, easy absorption, resistance to caking, and suitability for mechanized application.
Sulfur, the fourth major nutrient for crop growth, works synergistically with nitrogen to significantly enhance nitrogen use efficiency, promote protein synthesis, and strengthen crop resilience. EMCC Ammonium Sulfate Granules are specifically designed for modern agriculture, suitable for basal application, topdressing, and integrated water and fertilizer systems.
Why Choose Ammonium Sulfate Granules?
High Nitrogen and Sulfur Content
● Total Nitrogen (N) ≥20.5%
● Sulfur (S) ≥24.0%
Dual-nutrient synergy, particularly effective for sulfur-loving crops such as rapeseed, soybeans, onions, and tobacco.
Uniform Granules, Ideal for Mechanical Sowing
● Particle size 2–4mm, spherical structure
● High granule strength, resistant to breakage and dust
● Compatible with large seeders and spreaders, saving labor and time
Fully Water-Soluble, High Utilization Rate
● Rapid dissolution, no residue
● Suitable for drip irrigation, sprinkler irrigation, and fertigation
● Nutrient use efficiency improved by over 30% compared to conventional fertilizers
Improves Soil, Enhances Stress Resistance
● Sulfur helps regulate soil pH, improving saline-alkali land
● Enhances crop resistance to drought, cold, and disease
● Long-term use contributes to improved soil structure

Frequently Asked Questions (FAQ)
Answer: Ammonium sulfate granules not only provide nitrogen but also contain over 24% sulfur, whereas urea only provides nitrogen without sulfur. For sulfur-deficient soils or sulfur-loving crops, ammonium sulfate granules offer superior results, with less nitrogen volatilization and longer-lasting efficacy.
Answer: Yes. EMCC Ammonium Sulfate Granules are fully water-soluble and residue-free, making them highly suitable for fertigation systems such as drip and sprinkler irrigation. A preliminary solubility test is recommended before use.
Answer: The conversion of ammonium sulfate in soil releases hydrogen ions. Long-term or excessive use may lead to soil acidification. It is advisable to rotate with organic fertilizers or alkaline fertilizers, or adjust application rates based on soil pH.
Answer: Yes. We offer standard 25kg and 50kg woven bags, as well as bulk bags and custom logo packaging. Please contact our sales representative for details.
