Boron lignosulfonate (GAC-BLS) combines lignosulfonate with boron for foliar and soil micronutrient fertilizer formulations. This guide reviews the supplier-reported technical data and the checks needed before formulation or field use.
Supplier-Reported Technical Data
| Parameter | TDS value | Interpretation note |
| Appearance | Black powder | Confirm physical form on receipt. |
| Lignosulfonate, dry basis | 50% min | Confirm analytical method and reporting basis. |
| Boron as B2O3, dry basis | 1-3% min | B2O3-equivalent reference; confirm elemental-boron conversion before nutrient calculations. |
| Moisture | Around 15% | The source TDS lists this value with a "min" notation, which is unusual for a moisture spec; treat as a typical reference figure and confirm the actual limit and basis with the supplier. |
These are typical production values for reference, not binding specifications. Obtain an agreed current specification and an actual batch COA before acceptance.
Applications
This grade is intended for foliar and soil micronutrient fertilizer formulations, and may be evaluated together with calcium lignosulfonate in programs requiring combined calcium and boron delivery. The TDS references a soil-use starting point of 20-40 kg/ha and a blended-use reference of approximately 10% of the fertilizer mixture; both figures require confirmation against crop, soil analysis and local agronomic guidance before use, and should not be treated as a validated dosage recommendation. Suitability for correcting boron deficiency or supporting nutrient transfer to leaves and fruit should be confirmed through formulation and field trials for the intended crop and conditions.
Packaging and Storage
25 kg woven bags with polyethylene liner; customized packing is available on request. Store sealed in a cool, dry, well-ventilated area. Shelf life is 24 months in the original unopened packaging.
