Advantages:
1. High-concentration nutrients: 18% nitrogen + 46% phosphorus, total nutrients 64%. Nitrogen and phosphorus are synergistic, providing dual nutrients with one application.
2. Instantly soluble and easily absorbed: With water-soluble phosphorus content of ≥90%, it dissolves quickly and takes effect rapidly, making it suitable for base fertilizer, topdressing, and drip irrigation.
3. Weakly alkaline soil amendment: pH 7.5–8.2, neutralizing acidic soil, reducing phosphorus fixation, ensuring stable and long-lasting fertilizer effect (60–90 days).
4. Wide adaptability and easy mixing: The particles are uniform and do not pulverize, making them suitable for mixing with urea and potassium fertilizer. They are the core raw material for BB fertilizer.
5. High cost-effectiveness: Globally applicable phosphate fertilizer, with low transportation/application costs and significant yield increase.
Suitable crops
✅ Grain: wheat, corn, rice, sorghum (base fertilizer/seed fertilizer, to promote root growth and seedling strengthening).
✅ Cash crops: cotton, soybeans, rapeseed, potatoes, and sugar cane (promoting flowering, fruit expansion, and quality improvement).
✅ Fruits and vegetables: Tomatoes, peppers, watermelons, fruit trees (budding/fruit-expanding stage, sweetening and coloring).
✅ Soil: Optimal for neutral/acidic soil
Usage and recommended dosage:
Both manual and mechanical fertilization are convenient. It can be used as base fertilizer, seed fertilizer, and topdressing during the seedling stage. It can be mixed freely with various types of fertilizers.
For field crops, the dosage per hectare is 225–375 kilograms; while for fruits, vegetables, and fruit trees, it is 375–525 kilograms.
The specific dosage can be flexibly adjusted according to soil fertility and land conditions. When used together with urea and potassium fertilizer, it can achieve better yield and quality improvement.
Packing: 25kg, 50kg, 1000kg
