## Description

## Stabilised Boron Granules

Humic acid complexed boron for sustained release of this highly leachable nutrient. Boron as B2O3 is fused with humates and presented as a 2–4 mm granule for easier application and even distribution with granular fertiliser blends.

### Key Features and Specifications

- Formulation: humic acid complexed boron granules

- Typical analysis (w/w, dry basis): Boron 3.2% (approx. 3.23%); Humic Acids 57% (approx. 57.2%)

- Granule size: 2–4 mm

- Mode of action: sustained release in the root zone to support pollination, flowering, fruit set and fill

- Operational note: 2–4 mm granule for easy mixing with granular fertiliser

### Application and Usage Instructions
