For 3-year-old durian trees, a balanced fertilizer with a good mix of nitrogen (N), phosphorus (P), and potassium (K) is essential for healthy growth and fruit development. A common recommendation is a fertilizer with an NPK ratio of *15-15-15* or **16-16-16**, which provides equal amounts of these primary nutrients. Key Considerations: 1. **Nitrogen (N)**: Promotes leafy growth and overall tree vigor. 2. **Phosphorus (P)**: Supports root development and flowering. 3. **Potassium (K)**: Enhances fruit quality and disease resistance. Additional Tips: **Organic Fertilizers**: Incorporate organic matter like compost, manure, or biofertilizers to improve soil structure and nutrient availability. **Micronutrients**: Ensure the fertilizer includes micronutrients like magnesium, calcium, sulfur, zinc, and boron, which are crucial for durian trees. **Application Frequency**: Apply fertilizer every 2–3 months during the growing season. Avoid over-fertilizing, as it can harm the tree. **Soil pH**: Durian trees prefer slightly acidic soil (pH 5.5–6.5). Test the soil and adjust if necessary using lime (to raise pH) or sulfur (to lower pH). Example Fertilizer Application: Use *500–800 grams* of balanced NPK fertilizer per tree per application, depending on the tree's size and health. Split the application into 2–3 smaller doses throughout the year. Always monitor the tree's growth and adjust fertilization based on its needs. If possible, consult a local agricultural expert for region-specific recommendations.
