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.

  • 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.
