Extracted potassium humate
WSG Core
Water-soluble microgranule
Flagship soluble humate
The export-led core of the portfolio for fertigation, drip irrigation, foliar and seed programs.
Request product informationPRODUCT OVERVIEW
Designed as part of a complete soil system.
WSG Core converts extracted potassium humate into a low-dust, rapidly dispersible microgranule. It is designed as the common technical base for professional crop programs and later nutrient, micronutrient and biological WSG extensions.
FORMULATION CONTENT
- Extracted potassium humate
- Water-soluble humic and fulvic fractions
- Potassium from alkaline extraction

Apply in split doses through compatible irrigation systems
Use in foliar or seed programs only after crop-specific validation
PRODUCT SELECTION GUIDE
Water-soluble potassium humate microgranules
WSG Core is the soluble dry route for professional users who need low-dust handling, controlled pre-dissolution and flexible delivery through fertigation, drip, selected foliar or seed programs. Product selection must begin with water quality, required filtration and the intended application hardware.
Choose this route when
- A dry, concentrated and water-soluble humate form is required.
- Low dust and rapid dispersion matter in professional handling.
- One base product must serve more than one validated delivery route.
Verify before purchase or use
- Water hardness, bicarbonate load and solution pH
- Dissolution time, insoluble residue and final filtration
- Jar-test compatibility with fertilisers and crop-protection inputs
FREQUENTLY ASKED QUESTIONS
Technical questions about WSG Core
Is WSG Core the same as raw leonardite powder?
No. WSG Core is an extracted potassium-humate microgranule designed for dispersion in water; raw leonardite retains its natural mineral matrix and is not an equivalent soluble product.
Can WSG Core be injected directly into drip irrigation?
It should first be dissolved in clean water and evaluated against water quality, residue, filtration and emitter requirements. Final use follows the registered label and batch documentation.
Which documents should accompany a commercial batch?
The destination-market label, technical data sheet, safety data sheet and batch-specific quality documentation should define the released specification and handling conditions.
