Compound Fertilizer NPK15-5-23

This product is a high-potassium triple-nutrient compound fertilizer with a total nutrient content of ≥ 43%. It is produced using a roller granulation process, and its potassium content is significantly higher than that of similar products. It is suitable for the fruit expansion period, color change period, and stress resistance requirements of crops. The particles are uniform and suitable for long-distance transportation and storage under different climatic conditions worldwide. It is applicable to the critical potassium-demanding periods of fruits, vegetables, and economic crops, and can significantly enhance fruit hardness, sugar accumulation, and resistance to lodging.

1. Optimal Nutrient Ratio for High-Demand Crops​

The NPK 15-5-23 formula features a high potassium content (23%), which is crucial for enhancing crop resistance to diseases, pests, and environmental stress (such as drought and lodging). The balanced nitrogen (15%) and phosphorus (5%) levels promote robust vegetative growth, root development, and flowering/fruiting, making it ideal for cash crops like cotton, sugarcane, and certain vegetables that thrive with moderate chlorine levels.​

2. Efficient Nutrient Release & Absorption​

3.Cost-Effective & High-Yield Performance​

4. Suitable for Specific Soil & Crop Needs​

5. Easy Application & Versatility​

Root and Stem Crops (Potato)： During the tuber enlargement stage, tuber shape becomes uniform, starch accumulation increases

1. For sandy soil, apply fertilizers in 2-3 sessions (with an interval of 10 days), combined with water-retaining agents to reduce potassium loss. For saline-alkali soil, mix with gypsum to lower the inhibition of soil pH value on potassium absorption.

2. Do not mix with alkaline fertilizers such as lime and wood ash directly (with an interval of more than 3 days) to prevent nitrogen volatilization.

3. Storage temperature should be ≤ 38℃, relative humidity should be ≤ 70%, and the stacking of ton bags should not exceed 8 layers. Avoid rain and moisture exposure (moistened bags need to be crushed and sieved before reuse).
