Agricultural Compound Fertilizer
1. Product Overview
Agricultural Compound Fertilizer (Compound Fertilizer) is a fertilizer made of nitrogen (N), phosphorus (P), potassium (K) and other nutrients in a scientific ratio, with balanced nutrients, long-lasting fertilizer effect, easy to apply, etc. It is suitable for field crops, cash crops, fruits, vegetables and horticultural plants, and can significantly improve the yield and quality of crops.
2. Product Type
| Type | Feature | Common Ratio (N-P₂O₅-K₂O) | Applicable Crops |
|-------------------|--------------------------|--------------------------|---------------------------|
| High Nitrogen Type | Promote Stem and Leaf Growth | 25-10-10, 30-5-5 | Wheat, Corn, Leafy Vegetables |
| Balanced | Nutrient balanced and versatile | 15-15-15, 17-17-17 | Rice, Cotton, Fruit trees |
| High-Phosphorus | Promotes root development, enhances resistance | 10-20-10, 12-24-12 | Melon, fruit, tuber crops (potatoes) |
| High Potassium | Enhances fruit quality and sugar content | 10-10-30, 15-5-25 | Grapes, Citrus, Tobacco |
| Slow-release | Controlled release of nutrients to reduce loss | 18-9-12 (coated) | Cash crops, horticultural plants |
3. Core Advantages
✔ Scientific rationing: customized according to the fertilizer needs of crops, avoiding the shortcomings of single fertilization
✔ Efficient absorption: add chelated trace elements (such as zinc, boron, iron), improve the utilization rate
✔ Improve the soil: containing organic matter or humic acid, alleviate soil crusting
✔ Environmental protection and low consumption: slow-release technology reduces nutrient loss and reduces environmental pollution
