Fulvic Acids

The fulvic acids form a group of organic acids with inhomogeneous composition. Like the humic acids and humins, they are produced during decomposition of plant material (humification), but in comparison to humic acids, they have a significantly lower molar mass and more acidic characteristic. Fulvic acids are much better soluble in an acidic environment than humic acids – a property that can be used to separate both groups of substances. Fulvic acids give water a brownish-yellowish color and increase its COD value (chemical oxygen demand).


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.
