Description
Ammonium Sulfate Fertilizer
Produced by: Urmia Petrochemical Company
Ammonium Sulfate is a high-efficiency, inorganic fertilizer widely recognized for its dual nutrient value: nitrogen (N) and sulfur (S). With its crystalline white granules and high solubility, it is an essential product for modern agriculture and several industrial applications.
Product Overview
Ammonium sulfate [(NH₄)₂SO₄] is primarily used as a nitrogen fertilizer for alkaline soils. When applied to the soil, it releases ammonium ions that contribute to lowering pH levels, improving nutrient uptake efficiency, and enhancing plant growth. The sulfate form of sulfur is immediately available to crops, promoting the development of enzymes, vitamins, and chlorophyll.
Typical Specifications
Nitrogen (N): ≥ 20.5%
Sulfur (as SO₄): ≥ 23%
Moisture: ≤ 0.5%
Free Acid (H₂SO₄): ≤ 0.2%
Arsenic (As): ≤ 0.001%
Standards: ISO 5314, ISO 8190, ISO 10084, ISO 2993, ISO 17318
Applications
Agriculture: As a primary nitrogen and sulfur source for field crops, orchards, and greenhouses.
Chemical Industry: In the production of ammonium chloride, flame-retardant materials, and industrial adhesives.
Leather Industry: Used in tanning processes.
Soil Amendment: Especially effective for correcting pH imbalances in alkaline soils.
Packaging & Storage
The product is available in 50 kg palletized bags, ideal for bulk agricultural and industrial use. It should be stored in a cool, dry area, away from heat and direct sunlight. For detailed handling and safety instructions, please refer to the product’s Material Safety Data Sheet (MSDS).
Why Choose Ammonium Sulfate?
Dual Nutrient Action: Supplies both nitrogen and sulfur in immediately available forms.
Improves Alkaline Soils: Lowers pH and enhances nutrient absorption.
Safe & Stable: Unlike ammonium nitrate, it poses no explosion risk, making storage and transport safer.
Cost-Effective: Offers excellent value per unit of nitrogen and sulfur.
Compatible: Easily mixes with other fertilizers and fits into most crop nutrition programs.
Comparison with Other Fertilizers
Compared to urea, ammonium sulfate provides added sulfur and doesn’t cause volatilization as easily under certain conditions. While ammonium nitrate delivers quick-release nitrogen, it comes with regulatory challenges and storage risks. Ammonium sulfate, by contrast, is a stable, safer alternative with long-term soil health benefits.
