NPK 15‑5‑20 – 30-Day Controlled-Release Fertilizer
30-Day Nutrient Release for Short-Cycle Crops, Vegetables, and Greenhouse Plants
NPK 15‑5‑20 – 30-Day Controlled-Release Fertilizer
Nitrogen (N) 15% – supports vigorous vegetative growth and chlorophyll synthesis.
Phosphorus Pentoxide (P₂O₅) 5% – promotes efficient root development and early establishment.
Potassium Oxide (K₂O) 20% – enhances stress tolerance, improves fruit quality, and boosts water‑use efficiency.
30‑Day Controlled Release: Advanced polymer coating provides consistent nutrient supply for ~30 days, reduces losses, and minimizes reapplication frequency.
NPK 15-5-20 Short-Term CR Fertilizer Detailed Specifications
Terafon® NPK 15‑5‑20 Short-Term CR Fertilizer is a high-performance, polymer-coated controlled-release fertilizer engineered for 30-day nutrient release, designed to meet the precise needs of short-cycle and high-value horticultural crops, leafy vegetables, greenhouse vegetables, fruiting crops, and ornamentals.
Its advanced polymer coating technology ensures steady and predictable release of nitrogen (N), phosphorus (P₂O₅), and potassium (K₂O), reducing nutrient losses caused by leaching, volatilization, and runoff. This controlled-release mechanism improves nutrient use efficiency, promotes strong root and vegetative growth, and supports consistent, high-quality yields.
This fertilizer enables one-time application for the entire 30-day crop cycle, saving labor and operational costs while ensuring crops receive continuous, balanced nutrition.

Key Features & Agronomic Benefits
1. 30-Day Controlled Nutrient Release
- Provides a steady supply of N, P, and K throughout the critical early growth period, minimizing
2. High Nutrient Use Efficiency
- Polymer coating reduces nitrogen and potassium losses, improving uptake efficiency, lowering environmental impact, and promoting strong roots and vigorous vegetative development.
3. Labor & Cost Savings
- Single application sustains crops for 30 days, reducing repeated fertilization, labor input, and operational costs while maintaining consistent crop performance.
4. Targeted High-Potassium Support
- 15‑5‑20 formulation delivers elevated potassium, enhancing fruit development, stress tolerance, water-use efficiency, and overall crop quality.
5. Broad Crop Suitability
Ideal for horticultural crops, leafy greens, greenhouse vegetables, ornamentals, fruiting crops, and nursery seedlings, ensuring reliable performance across diverse cropping systems.
Application & Usage Guidelines
Application Methods
- Soil Broadcast: Spread granules evenly before sowing or transplanting.
- Band Placement: Place fertilizer bands along crop rows for localized nutrition.
Mechanized or Manual Spread: Suitable for small- and large-scale applications.
Best Practices
- Conduct soil or tissue analysis to determine nutrient requirements.
- Apply granules evenly or in bands depending on crop type.
- Irrigate after application to activate the polymer coating.
- Adjust application rates based on crop stage and soil fertility.
Note: Controlled-release design eliminates the need for reapplication within the 30-day growth cycle.
Recommended Crops
- Leafy vegetables and quick-maturing crops
- High-value horticultural crops
- Greenhouse vegetables and ornamentals
- Fruiting crops: tomatoes, peppers, cucurbits
Nursery seedlings and transplants
Packaging & Storage
