Potassium Fulvate
Potassium fulvate is the potassium salt of fulvic acid, a low‑molecular water-soluble humic fraction from mineral humus. Rich in carboxyl and phenolic hydroxyl groups, it has chelating and ion-exchange properties, good water solubility and anti-flocculation features. It serves as raw material for liquid and water-soluble fertilizers.

Description
Potassium Fulvate features high solubility. It is a naturally organic material containing a range of nutrients required by crops. Its active functional groups in the molecular structure can chelate immobilized secondary and trace elements in soil, such as calcium, magnesium, iron and zinc, converting these nutrients into forms with higher availability.
This product is naturally organic, water-soluble, high in activity, and compatible with other materials. It has anti-flocculation properties. It serves as an ideal raw material or base for formulating various liquid and water-soluble fertilizers, and can be used in drip irrigation and foliar spray formulations. It is a green option for sustainable agriculture.
Specification
Application
- In agriculture, Potassium fulvate improves soil, also be used as a fertilizer.
- In fertilizers, used for producing compound fertilizers and water-soluble fertilizers.
- In industry, it is used as a processing agent, ion exchange agent, etc.
Function
- Rich in diverse small‑molecule active functional groups, it acts as a natural biological stimulant.
- Humic substances own unique macromolecular structures with highly active functional groups.
- They are carbon-rich organic compounds formed by natural organic degradation processes.
- These natural organic components have inherent chelating and adsorption physicochemical properties.
- They present stable pH-buffering characteristics under natural soil conditions.
- As typical natural organic fractions, humic materials constitute part of the basic organic composition of soil.
