Humic acid is a kind of animal and plant remains, mainly plant remains, a type of organic matter produced and accumulated by microbial decomposition and transformation, and a series of geochemical processes. The most promising resources for humic acid development are low-calorie coals such as peat, lignite and weathered coal. Among them, the humic acid content is 10-80%.
Humic acid is a macromolecular organic substance widely found in nature. It is widely used in agriculture, forestry, animal husbandry, petroleum, chemical, building materials, medical and health, environmental protection and other fields. In particular, it now advocates the construction of ecological agriculture, pollution-free agricultural production, green food, pollution-free environmental protection, etc., and makes "humic acid" highly respected. It turns out that human life and survival are inseparable from humic acid.
