Product overview
Mineral fulvic acid is the smallest, most soluble humic fraction, extracted from leonardite and lignite. It dissolves at any pH and carries nutrients into plants, which makes it a common carrier in foliar and fertigation products.

What it does
- Soluble at all pH values
- Chelates micronutrients for foliar and fertigation use
- High exchange capacity relative to humic acid
- Compatible with most NPK and trace-element solutions
How it is used
Use as a carrier in foliar sprays and fertigation, or as the fulvic base of liquid fertilizers. Grades differ in fulvic content and pH; the neutral grade suits acidic formulations.
Packing and documents
25 kg woven or kraft bags with an inner liner; jumbo bags and private-label packing on request. TDS and SDS for every grade, a representative COA before you order and a COA with every lot. Request documents or a sample.

FAQ
Mineral or bio fulvic acid?
Mineral fulvic acid comes from leonardite and is high in fulvic acid; bio fulvic acid is fermented from plant material and also contains sugars and amino acids.
Why does fulvic acid dissolve at low pH?
Its molecules are small and carry many acidic groups, so they stay in solution even in acidic conditions.
