NPK 18‑4‑6 Long-Term Controlled-Release Fertilizer
120–140 Days Steady Nutrition for Early Growth, Crop Uniformity, and High Yield
NPK 18‑4‑6 Long-Term Controlled-Release Fertilizer
Phosphorus Pentoxide (P₂O₅) 4% – supports root establishment, flowering, and nutrient uptake.
Potassium Oxide (K₂O) 6% – enhances stress tolerance, disease resistance, and overall plant vigor.
Long-Term Controlled Release – polymer-coated granules supply nutrients steadily for 120–140 days, improving uptake and reducing losses.
NPK 18‑4‑6 Fertilizer Detailed Specifications
Terafon® NPK 18‑4‑6 Long-Term Controlled-Release Fertilizer is engineered for high-performance crops requiring early growth stimulation with moderate potassium support. Its nitrogen-rich formulation supports strong vegetative development, while the controlled-release polymer coating ensures predictable nutrient availability throughout key growth stages.
The fertilizer enhances nutrient use efficiency (NUE), reduces environmental impact, and supports sustainable agriculture practices in intensive cropping systems.

Key Features & Agronomic Benefits
1. Early Growth and Nitrogen-Rich Nutrition
- The 18–4–6 NPK ratio provides strong early vegetative growth while supplying essential phosphorus and potassium for root development and crop stress resilience.
2. Predictable Long-Term Nutrient Release
- Polymer-coated granules release nutrients gradually in alignment with crop demand, supporting consistent growth from seedling to harvest.
3.Enhanced Nutrient Use Efficiency
- Reduces nitrogen volatilization and potassium leaching, improving fertilizer efficiency and minimizing environmental impact.
4. Reduced Application Frequency
- Extended-release nutrition supports the crop cycle with fewer applications, saving labor and operational costs.
Application & Usage Guidelines
Application Methods
- Pre-Plant Broadcasting: Apply evenly before planting and incorporate into soil
- Band or Row Placement: Near root zone for efficient uptake
Soil Incorporation: Suitable for orchards, raised beds, nurseries, and containers
Best Practices
- Adjust application rates based on soil tests and crop nutrient requirements
- Apply before irrigation or rainfall to activate controlled nutrient release
- Avoid mixing with incompatible agrochemicals
Additional fertilization during the controlled-release period is generally unnecessary
Recommended Crops
- Leafy vegetables, solanaceae, cucurbits
- Ornamentals and nursery plants
- Perennial plantations and landscaping crops
- High-value horticultural crops requiring uniform early growth
Turfgrass and professional landscaping projects
Packaging & Storage
- Packaging Options: 25 kg & 50 kg woven PP bags; 500–1,000 kg jumbo bags.
- Storage Conditions: Cool, dry, ventilated warehouse; protect from moisture and direct sunlight.
Shelf Life: Anti-caking treated for long-term storage and handling stability.
