    In regards to sources of humic acid Dr Robert E Pettit states that “The quality and value of any mined humate or humic acid product depends on many different factors A good humic material can be destroyed by improper mining or processing, thus not all commercially marketed humic substances are equal in quality It is very difficult for individuals purchasing a HA to tell the differenceThe commercial employment of brown coal containing humic acid eg as coloring material under the designation “Cologne brown” from Cologne lignite mining area and “Kassler brown” goes back to 19th century in Germany In the course of the last century the use of humic acid has been established in the agricultural, medical and environmental sector Humintech is a German technologyWhat are Humic Acids?
