Appearance | White grey original color |
| Nitrogen content(N) | 13% | |
| Nitrate Nitrogen content(NO3-) | 5.2% | |
| Phosphorus Content (P2O5) | 5% | |
| Kalium Content (K2O) | 28% | |
| Total content (N+P+K) | 46% | |
| Moisture Content | ≤2.0% | |

| Particle size range | 1-4mm>=90% |
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).
Fast & Sustained Nutrition: 5% nitrate nitrogen delivers instant absorption, while 8% ammonium nitrogen ensures prolonged nutrient supply.
Sulfur Enrichment: Enhances protein synthesis, improves fruit sweetness, color, and shelf life.
Chloride-Free Safety: Potassium sulfate avoids chloride damage, perfect for chlorine-sensitive crops like strawberries, grapes, and tobacco.
High Potassium Boost: 28% K2O strengthens disease resistance, reduces lodging, and promotes fruit expansion and coloration.
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.
| Crop Type | Dosage | Application Timing |
|---|---|---|
| Vegetables (tomato, cucumber) | 30-40kg/mu* | Base + topdressing during fruit expansion |
| Fruit trees (citrus, grape) | 1.5-2kg/tree | Budding stage and fruit expansion stage |
| Cash crops (tobacco, tea) | 25-35kg/mu | Split into 2-3 doses post-transplant |
| Field crops (corn, wheat) | 20-30kg/mu | Pre-sowing base application |
*1 mu ≈ 0.1647 acre. Adjust dosage based on soil fertility and yield goals.
Science-Backed Formula: Tailored NPK + sulfur ratios maximize crop uptake and ROI.
Eco-Friendly: Chloride-free, heavy-metal-free, and soil-friendly for sustainable farming.
Expert Support: Free crop-specific fertilization plans and agronomic guidance.
We can not only provide the following conventional packaging, but also customize other types of packaging according to your needs.
