  • Spread evenly on soil surface or in bands before sowing or transplanting.

  • Adjust rates according to soil fertility, crop type, and growth stage.

  • No reapplication needed within 30 days due to controlled-release technology.

Usage Guidelines

  • Conduct soil or tissue analysis to determine nutrient requirements.

  • Apply granules evenly using mechanical spreaders or manually for small-scale cultivation.

  • Incorporate into soil or irrigate after application to activate polymer-coated granules.

  • Adjust application rates based on crop type, growth stage, and soil fertility.

  • For fertigation or foliar-ready formulations, follow dilution and application instructions specific to crop and stage.

Packaging & Storage
