NPK 19-6-13 90-Day Controlled-Release Fertilizer
High-Nitrogen, Long-Lasting Nutrition for Vigorous Growth and Sustainable Yields

NPK 19-6-13 90-Day Controlled-Release Fertilizer
- Nitrogen (N) 19% – supports vigorous vegetative growth and canopy development.
- Phosphorus Pentoxide (P₂O₅) 6% – promotes early root growth and efficient nutrient uptake.
- Potassium Oxide (K₂O) 13% – enhances stress tolerance, water balance, and crop quality. 90-Day Controlled Release – polymer-coated granules provide steady nutrient release for ~90 days, reducing losses and re-application needs.
NPK 19-6-13 90Day CR Fertilizer Detailed Specifications
Terafon® NPK 19-6-13 90-Day Controlled-Release Fertilizer is a high-performance, nitrogen-forward NPK formulation engineered for crops with strong vegetative growth requirements and extended production cycles. The optimized N-K balance supports continuous growth momentum while maintaining plant resilience and yield stability.
Unlike conventional fertilizers, the controlled-release coating technology delivers nutrients gradually in response to soil moisture and temperature, ensuring predictable nutrient availability, improved fertilizer efficiency, and reduced environmental impact.

Key Features & Agronomic Benefits
1. High-Nitrogen Energy for Rapid Crop Development
- With 19% nitrogen, this formulation supports fast canopy formation, strong leaf development, and high photosynthetic efficiency—ideal for crops requiring continuous vegetative growth.
2. Controlled & Predictable Nutrient Supply
- The polymer coating ensures nutrients are released gradually rather than in bursts, preventing early nutrient excess and late-season deficiencies commonly associated with conventional fertilizers.
3. Improved Nutrient Use Efficiency
- Controlled diffusion significantly reduces nitrogen leaching and volatilization losses, resulting in higher nutrient uptake efficiency and more sustainable fertilizer programs.
4. Optimized for Intensive Production Systems
- Designed for commercial agriculture, greenhouse cultivation, and high-input cropping systems where consistent nutrient availability and labor efficiency are critical.
Application & Usage Guidelines
Application Methods
- Pre-Plant Broadcasting: Establishes a stable nutrient base before planting or transplanting
- Band or Row Application: Places nutrients closer to the root zone for improved efficiency
- Soil Incorporation: Suitable for raised beds, greenhouse substrates, and container systems
Best Practices
- Adjust application rates based on soil analysis and target yield
- Apply prior to irrigation or rainfall to activate the controlled-release coating
Avoid direct mixing with incompatible agrochemicals
Note: In most cases, no additional nitrogen fertilization is required during the 90-day release period.
Recommended Crops
- High-yield vegetables and leafy crops
- Fruit crops and orchards
- Field crops and cereals
- Forage and biomass production
Nursery plants and ornamental crops
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.
