Humic Acid Complex

The humic acid complex (also called clay-humus complex) in soil science refers to aggregate formation of organic fragments (e.g. humic substances) and inorganic particles (e.g. clay minerals). It is accomplished either by hydrogen bonding or the incorporation of metallic cations. Clay minerals and humic substances are both soil colloids. Humic substances can combine individual soil particles into a crumb structure and thus stabilize the soil structure. Such aggregate structures develop in humic top soils when clay colloids connect with humic substances by means of calcium bonding.


Humintech is a biotech company based in Grevenbroich, Germany. We are primarily focused on the research, development and industrial production of humic matter and humic acids for the agricultural sector.  Our products find further use in the feed, pharmaceutical and construction industry, in veterinary medicine and for ecological purposes such as water purification and soil decontamination.
