We’re dedicated to the development and manufacture of pure, safe, and effective humic substances. The veracity of reporting humic substance content is of extreme importance. The Humic Products Trade Association (HPTA) and International Humic Substances Society (IHSS) have developed a new testing method for the determination of the hydrophobic fulvic acid fraction of humic products. This method was first published in the Journal of AOAC International and his since been approved by the American Association of Plant Food Chemist Officials (AAPFCO) and the International Standards Organization (ISO) for international recognition and use.
As part of our commitment to product quality, we are pleased to use the IHSS/Lamar/AOAC method as the standard for identifying the hydrophobic fulvic acid fraction of humic substances.
