Humic acid is a naturally occurring material found in soils, lignite and composting vegetable matter. Rich Humic lab results show 22% humic acid through the alkaline extraction method and 3% humic acid through the acid insoluble method. Because some states recognize only the acid insoluble method, we list Rich Humic at 3% humic acid.
