1. Product Specifications

  • Total Nutrients: 46% (N-P2O5-K2O = 13-5-28)

  • Nitrogen Composition: 5% nitrate nitrogen + 8% ammonium nitrogen (fast-acting + sustained release).

  • Potassium Source: Potassium sulfate (chloride-free formula, ideal for chlorine-sensitive crops).

  • Production Process: High-tower granulation.

  • Granule Properties: Uniform, round, highly water-soluble, dust-free.

  • Suitable Crops: Fruits, vegetables, cash crops (e.g., tobacco, grapes), and field crops (e.g., corn, wheat).

  • Packaging: 25kg/bag, 40kg/bag (customizable).

 

2. Key Advantages of Nitrate-Sulfur-Based Fertilizer

  1. Fast & Sustained Nutrition: 5% nitrate nitrogen delivers instant absorption, while 8% ammonium nitrogen ensures prolonged nutrient supply.

  2. Sulfur Enrichment: Enhances protein synthesis, improves fruit sweetness, color, and shelf life.

  3. Chloride-Free Safety: Potassium sulfate avoids chloride damage, perfect for chlorine-sensitive crops like strawberries, grapes, and tobacco.

  4. High Potassium Boost: 28% K2O strengthens disease resistance, reduces lodging, and promotes fruit expansion and coloration.

 

3. Benefits of High-Tower Granulation

  • Uniform Nutrients: High-temperature melting ensures consistent nutrient distribution in every granule.

  • Rapid Dissolution: Porous structure allows quick disintegration, ideal for drip irrigation or foliar application.

  • Anti-Caking & Durability: Smooth, dense surface minimizes moisture absorption and storage issues.

 

4. Recommended Usage & Dosage

Crop TypeDosageApplication Timing
Vegetables (tomato, cucumber)30-40kg/mu*Base + topdressing during fruit expansion
Fruit trees (citrus, grape)1.5-2kg/treeBudding stage and fruit expansion stage
Cash crops (tobacco, tea)25-35kg/muSplit into 2-3 doses post-transplant
Field crops (corn, wheat)20-30kg/muPre-sowing base application

*1 mu ≈ 0.1647 acre. Adjust dosage based on soil fertility and yield goals.
