1. What It Is:
NPK fertilizer is a blended or compound fertilizer that contains three essential macronutrients for plant growth:
- N – Nitrogen: Promotes leafy growth and chlorophyll production
- P – Phosphorus: Supports root development and flowering
- K – Potassium: Enhances overall plant health, resistance, and fruiting
2. Common NPK Ratios:
- 10-10-10 – Balanced for general use
- 20-20-20 – High strength, all-purpose
- 15-15-15 – Moderate, well-rounded
- Specific blends: 12-24-12 (for root growth), 6-12-12 (for fruiting crops), etc.
3. Types:
- Compound (Complex): All nutrients in one granule
- Blended (Bulk Blend): Separate nutrient granules mixed together
- Water-Soluble NPK: For drip irrigation or foliar application
4. Applications:
- Used for all crops, including grains, vegetables, fruits, and lawns
- Applied before planting, during growth stages, or through fertigation
5. Advantages:
- Delivers balanced nutrition in one application
- Enhances crop yield and quality
- Customizable blends for specific crops and soils
6. Storage & Packaging:
- Stored in cool, dry areas to prevent clumping
