Leonardite Humic Acid

Specifications

Humic Acid Content (dry basis): 40%min, 50%min, 65%min, 70%min

Humic Acid

 

Property:

It is a principal component of humic substances which are the major organic constituents of soil, (humus), peat, coal, many upland streams, dystrophic lakes and ocean water, produced by biodegradation of dead organic matter. It is not a single acid, rather, it is a complex mixture of many different acids containing carboxyl and phenolate groups so that the mixture behaves functionally as a dibasic acid or, occasionally, as a tribasic acid. Humic acids can form complexes with ions that are commonly found in the environment.
