    Application of Single Super Phosphate

    Purity 16% P2O5: Single Super Phosphate with 16% P2O5 purity is used in cereal crop cultivation, where it enhances early root development and increases phosphorus bioavailability.

    Particle size 90% passing 1 mm sieve: Single Super Phosphate with 90% passing 1 mm sieve is used in precision agriculture, where uniform granule size ensures even nutrient distribution in soil.

    Water solubility ≥ 85%: Single Super Phosphate with ≥ 85% water solubility is used in drip irrigation systems, where rapid dissolution facilitates efficient nutrient uptake by plants.

    Moisture content ≤ 5%: Single Super Phosphate with ≤ 5% moisture content is used in bulk storage facilities, where minimal caking improves handling and application efficiency.

    Free acidity max 4%: Single Super Phosphate with maximum 4% free acidity is used in fruit orchards, where reduced soil acidification maintains long-term soil health.

    Stability temperature up to 40°C: Single Super Phosphate with stability up to 40°C is used in tropical field conditions, where the fertilizer retains its granular integrity and reactivity.

    Cadmium content ≤ 30 ppm: Single Super Phosphate with ≤ 30 ppm cadmium content is used in vegetable farming, where reduced heavy metal levels ensure food safety and regulatory compliance.

    Packing & Storage
    Packing Single Super Phosphate is typically packaged in durable 50 kg woven polypropylene bags, clearly labeled with product name, quantity, and safety information.
    Container Loading (20′ FCL) 20′ FCL can load about 25 MT of Single Super Phosphate, packed in 50 kg bags, arranged securely for safe transport.
    Shipping Single Super Phosphate (SSP) should be shipped in moisture-proof, well-sealed bags or bulk containers. It must be kept dry and protected from direct sunlight and rain. SSP is non-flammable but should be handled with care to prevent dust formation. Proper labeling, secure stacking, and compliance with local transport regulations are essential.
    Storage Single Super Phosphate (SSP) should be stored in a cool, dry, and well-ventilated area, away from moisture and direct sunlight to prevent caking and deterioration. Storage areas must be free from combustible materials and sources of ignition. SSP should be kept in tightly sealed, labeled bags or containers, placed on pallets to avoid contact with the floor.
    Shelf Life Single Super Phosphate has an indefinite shelf life if stored in a dry, moisture-free environment, preventing caking and loss of effectiveness.
