NPK Complex 12:11:18 is a granular compound fertilizer designed to provide balanced primary nutrients throughout the crop growth cycle. With a higher potassium content, it is particularly suited for crops requiring strong fruiting, better quality produce, and improved stress tolerance.

It ensures steady nutrient availability in the root zone, supporting uniform vegetative growth, efficient energy transfer, and improved reproductive development. This formulation is widely used across field crops, horticultural crops, and plantation crops for consistent yield and quality improvement.

Mode of Action

• Nitrogen promotes vegetative growth and chlorophyll synthesis
• Phosphorus supports root development, energy transfer (ATP), and early crop establishment
• Potassium regulates water balance, enzyme activation, and improves fruit quality and stress tolerance
• Works by supplying readily available nutrients to the root zone for continuous uptake

---

Mode of Entry

Root uptake through soil application (mobile nutrient absorption via mass flow and diffusion)

---
