Frequently Asked Questions
Controlled‑Release NPK Fertilizer is a precision-coated compound fertilizer that gradually releases nitrogen (N), phosphorus (P₂O₅), and potassium (K₂O) over a specified period. This ensures consistent nutrient availability, reduces leaching, and improves fertilizer efficiency for all crop types.
The ideal release period depends on the crop type, growth cycle, soil conditions, and climate. Short-term CR (30 days) suits fast-growing crops, medium-term (60–90 days) for seasonal crops, and long-term (120+ days) for perennials or long-cycle crops. Soil tests can guide precise selection.
Controlled‑Release NPK minimizes nutrient loss, reduces labor and application frequency, improves nutrient uptake efficiency, promotes steady root and vegetative growth, and supports sustainable soil health. It enhances crop yield and quality compared to conventional fertilizers.
Terafon offers custom CR NPK formulations based on crop requirements and soil analysis. Our technical team can provide tailored solutions for nutrient balance, release duration, and specific micro-nutrient inclusion.
