1, Product Specifications:
- NPK Ratio: 22-9-9
- Nitrogen Source: High Nitrate Nitrogen (≥8%)
- Formulation: Granular
- Main Nutrients:
- Nitrogen (N): 22%
- Phosphorus (P2O5): 9%
- Potassium (K2O): 9%
- Secondary Nutrients: Sulfur (S)
- Granule Size: Standard (2-4 mm)
Our NPK 22-9-9 fertilizer is produced using the high tower granulation process, ensuring uniform granule size, easy handling, and excellent solubility. This process guarantees:
- Highly Efficient Nutrient Release: The controlled granulation ensures slow, steady release of nutrients to the plant, reducing nutrient loss and improving uptake efficiency.
- Enhanced Durability: Granules are strong and resistant to crushing, preventing dust formation and losses during transportation and application.
- Optimal Storage and Application: The uniform size and shape of the granules make it easier for both automated and manual spreaders to apply the fertilizer accurately.
3, High Nitrate Nitrogen - A Key Benefit for Plants
This fertilizer contains a high nitrate nitrogen content (≥8%), which provides plants with nitrogen in a highly soluble and plant-available form. The key benefits of high nitrate nitrogen include:
- Rapid Uptake and Response: Nitrate nitrogen is absorbed quickly by plants, promoting fast growth, green leaf development, and overall plant vigor.
- Improved Nitrogen Utilization: Plants efficiently use nitrate nitrogen, reducing the risk of nitrogen loss through volatilization or leaching.
- Reduced Ammonium Toxicity: Nitrate nitrogen is less likely to cause toxicity compared to ammonium-based fertilizers, making it suitable for a wide range of crops.
4, Sulphate of Potash (SOP) - Potassium Source for Plant Health
Our NPK 22-9-9 formulation includes Sulfate of Potash (SOP) as the potassium source, offering several distinct advantages:
- Enhanced Crop Quality: SOP delivers potassium without adding excess chloride, improving the quality of fruits, vegetables, and other crops sensitive to chloride.
- Improved Stress Tolerance: Potassium derived from SOP enhances the plant's ability to withstand environmental stresses such as drought, heat, and disease.
- Efficient Potassium Uptake: The sulfate form of potassium ensures easy absorption by plants, supporting strong root development and overall plant growth.
5, Recommended Crops & Application Guidelines
NPK 22-9-9 is suitable for a wide range of crops, providing balanced nutrition that supports both vegetative growth and fruit production. Below are the recommended crops and usage instructions:



. Vegetables (Tomatoes, Lettuce, Cucumbers, etc.)
- Application Rate: 300-400 kg/ha
- Usage: Apply in early spring before planting, or as a side dressing during the growing season. For tomatoes, a split application of 50% before planting and 50% during the flowering stage is recommended.
. Fruits (Citrus, Apples, Pears, etc.)
- Application Rate: 250-350 kg/ha
- Usage: Apply in early spring before new growth begins, or as a top dressing during the growing season. For fruit trees, apply in a band around the root zone and water thoroughly.
. Field Crops (Corn, Wheat, Rice, etc.)
- Application Rate: 200-300 kg/ha
- Usage: Apply as a base fertilizer before planting or during early growth stages. For corn, apply in two splits-one before planting and the second at the V6 stage for optimal growth.
. Flowers & Ornamental Plants
- Application Rate: 150-250 kg/ha
- Usage: Apply as a general-purpose fertilizer in early spring to support growth and flowering. Reapply once during the blooming period for enhanced performance.
General Application Tips:
- Irrigation: For best results, ensure the fertilizer is incorporated into the soil either through irrigation or mechanical mixing.
- Soil Testing: Conduct regular soil tests to ensure nutrient levels are balanced for optimal crop performance.
