potassium humate (K-humate) is one of the major components
of humic substances. Potassium humate is obtained by alkaline
extraction of lignite or brown coal or leonardite and is used
commercially as a soil conditioner. Chemically, it is a super-molecular heterogeneous
aromatic hydroxy carboxylic acid composed by various functional
groups, taking on effects of sorption, complexation, chelation,
flocculation, which dissolves loads of
hydrophobic matters.
