    🌾 Ammonium Sulphate (NH₄)₂SO₄ – Premium Nitrogen & Sulfur Fertilizer

    Chemical Name: Ammonium Sulphate
    CAS Number: 7783-20-2
    Molecular Formula: (NH₄)₂SO₄
    Nitrogen Content (N): 21%
    Sulfur Content (S): 24%
    Physical Form: White or off-white crystalline granules or powder
    Packaging: 25kg/50kg woven PP bags or jumbo bags
    HS Code: 31022100


    📦 Product Overview:

    Ammonium Sulphate is a widely used nitrogen-based fertilizer that also supplies sulfur, an essential nutrient that enhances crop yield and quality. This dual-nutrient formulation makes it especially suitable for sulfur-deficient soils and for crops requiring high sulfur content like canola, alfalfa, rice, potatoes, and other vegetables.


    ✅ Key Benefits:

    • ✔️ Provides a fast-acting source of nitrogen and sulfur

    • ✔️ Improves protein synthesis and chlorophyll formation

    • ✔️ Enhances plant resistance and boosts crop yield

    • ✔️ Lowers soil pH – ideal for alkaline soils

    • ✔️ Highly soluble and easy to apply via broadcast or fertigation


    🌱 Applications:

    • Used as a direct-application fertilizer

    • Can be mixed with other fertilizers or micronutrients

    • Suitable for a wide range of crops: cereals, legumes, fruits, vegetables, and turf


    🔒 Storage & Handling:

    • Store in a dry, ventilated area away from moisture

    • Avoid contact with strong oxidizers and moisture to prevent caking

    • Non-hazardous, but protective gear is recommended when handling


    🌍 Widely Used In:

    Agriculture, industrial applications (e.g., flame retardants, water treatment), and feed-grade supplements in specific formulations.

    🧪 Ammonium Sulphate Fertilizer – High-Quality Nitrogen & Sulfur Source for Agricultural & Industrial Use

    Product Name: Ammonium Sulphate
    CAS No.: 7783-20-2
    Chemical Formula: (NH₄)₂SO₄
    Appearance: White or slightly off-white crystalline granules or powder
    Grade: Agricultural / Industrial
    Packaging: 25kg, 50kg PP woven bags with PE liner or jumbo bags
    Purity: ≥99.5%
    Solubility: Completely soluble in water


    📌 Product Description:

    Ammonium Sulphate is an inorganic salt widely used as a fertilizer and soil conditioner. It provides two vital nutrients—nitrogen (21%) and sulfur (24%)—in a form readily absorbed by plants. This makes it ideal for crops grown in sulfur-deficient areas and for improving crop quality and yield. Beyond agriculture, it also sees use in various industrial applications, such as water treatment, textile dyeing, and flame retardants.


    🌾 Agricultural Applications:

    • Enhances nitrogen uptake: Promotes lush green growth and boosts chlorophyll production.

    • Sulfur source: Vital for amino acid and enzyme production in crops.

    • Acidifying effect: Helps balance alkaline soils, improving nutrient availability.

    • Application methods: Suitable for direct soil application, broadcasting, or incorporation into blends.

    🌍 Suitable for Crops Like:

    Rice, wheat, cotton, sugarcane, corn, oilseeds, vegetables, fruits, and pasture grasses.


    ⚙️ Industrial Applications:

    • Used in fireproofing materials, textile dyeing, water purification, and pharmaceuticals.

    • Acts as a flocculant in water treatment.

    • Used as a food additive in specific regulated industries.


    🛡️ Storage & Safety:

    • Store in a cool, dry place, away from moisture and direct sunlight.

    • Keep the bag tightly sealed after opening.

    • Not classified as hazardous but use gloves and eye protection during handling.
