    • Available Phosphorus (P₂O₅): 30-40%

    • Form: Granular or Powdered

    • Color: Dark gray to brownish

    • Solubility: Low solubility (slow-release)

    • Moisture Content: ≤2%

    • Particle Size: 100% passing through 10 mesh sieve

    • Packaging: 25kg, 50kg PP/PE bags or bulk supply (custom packaging available)


    Product Benefits:

    • 🌱 Rich in Phosphorus: Provides plants with a steady and continuous supply of phosphorus, essential for root development, flowering, and fruiting.

    • 🌍 Eco-Friendly: 100% natural, suitable for organic farming and sustainable practices.

    • 🌾 Improves Soil Quality: Enhances soil fertility by boosting microbial activity and improving pH balance.

    • 🌻 Increases Crop Yield: Essential for crops like cereals, legumes, vegetables, and fruit trees.

    • 💧 Slow-Release: Provides long-term benefits with minimal risk of phosphorus leaching or runoff.


    Applications:

    Rock Phosphate is best suited for:

    • Crops: Corn, wheat, rice, sugarcane, soybeans, and more

    • Fruits & Vegetables: Apples, tomatoes, potatoes, carrots

    • Organic Farming: Certified for organic use, it meets organic farming guidelines.

    • Soil Amendment: Improves the availability of phosphorus in acidic soils and enhances root growth.


    Recommended Usage:

    Rock Phosphate – Premium Natural Fertilizer for Sustainable Agriculture and Optimal Crop Growth

    Overview:
    Rock Phosphate is a natural, highly effective source of phosphorus, one of the three primary nutrients essential for plant growth. Extracted from phosphate rock, this mineral is a staple in sustainable and organic farming. It plays a vital role in strengthening plant root systems, enhancing flowering and fruiting, and improving overall crop yields. Our premium Rock Phosphate is perfect for improving soil health while minimizing the environmental impact associated with synthetic fertilizers.


    Product Specifications:

    • CAS Number: 7758-87-4

    • Chemical Formula: Ca₃(PO₄)₂

    • Available Phosphorus (P₂O₅): 30-40%

    • Form: Granular or Powder

    • Color: Dark gray to brownish

    • Moisture Content: ≤2%

    • pH Value: Neutral to slightly alkaline

    • Particle Size: 100% passing through a 10-mesh sieve

    • Packaging: Available in 25kg and 50kg bags or bulk orders (custom packaging available)


    Key Benefits of Rock Phosphate:

    • 🌿 Rich in Essential Phosphorus: Phosphorus is a critical element that aids in energy transfer, root growth, flowering, and fruiting in plants. Rock Phosphate provides plants with a steady, slow-release source of phosphorus, ensuring healthy growth throughout the growing season.

    • 🌏 Environmentally Friendly: Unlike synthetic fertilizers, which can leach into the environment and cause pollution, Rock Phosphate is naturally occurring, making it ideal for sustainable farming practices.

    • 🌻 Improves Soil Health: Over time, Rock Phosphate increases soil fertility by enhancing its ability to hold onto essential nutrients. It also encourages beneficial soil microorganisms that improve overall soil health and structure.

    • 🏞 Slow-Release for Long-Term Results: This product provides slow-release phosphorus, meaning nutrients are delivered gradually, reducing the risk of nutrient leaching and promoting long-lasting soil fertility.

    • 🍅 Increases Crop Yield: Suitable for a wide range of crops, Rock Phosphate supports vigorous plant growth and higher yields of vegetables, fruits, and grains.


    Product Uses:

    • For Crops: Ideal for cereals (wheat, corn), grains, legumes (soybeans, peanuts), and vegetables (potatoes, tomatoes).

    • Fruit and Tree Crops: Perfect for fruit-bearing plants like apples, oranges, grapes, and tree crops like avocado, almonds, and citrus.

    • Organic Farms: Certified for organic farming, this natural phosphorus source adheres to organic guidelines and can be used in various certified organic systems.

    • Soil Amendment: Helps raise phosphorus levels in soils that are deficient in this crucial nutrient. It’s especially beneficial for acidic soils, where phosphorus availability is typically lower.


    How to Use Rock Phosphate:

    • Pre-planting Soil Application: For best results, incorporate Rock Phosphate into the soil before planting crops. This allows it to interact with the soil for better phosphorus availability during the growing season.

    • Top Dressing for Established Crops: For plants already growing, Rock Phosphate can be broadcasted around the base of the plant as a top dressing. It is best applied during early growth stages or before the flowering phase.

    • Recommended Application Rate: Application rates may vary depending on crop type, soil condition, and the phosphorus level in the soil. A general recommendation is 100-300 kg per hectare, but it's ideal to conduct a soil test for precise dosage.


    Storage & Handling:

    • Store Rock Phosphate in a cool, dry place away from moisture to maintain product effectiveness.

    • Ensure proper sealing of packaging after use to preserve the product's quality.
