In recent years, the research and application of mineral-source humic acid has promoted the development and development of agriculture, gardening, animal husbandry, breeding, medicine and health, industry, environmental protection and other fields. So do you know what mineral-source humic acid is? And The formation process? The following content will explain it in detail for you.
What is mineral humic acid?
Mineral source humic acid is an organic substance accumulated and formed from animal and plant remains, mainly plant remains, through the transformation and decomposition of microorganisms and a series of natural physical and chemical processes on the earth. The main component of organic matter is carbon. Usually, most of the organic matter components that we can come into contact with are carbon chains, and the mineral humic acid carbon is a benzene ring.
The chemical elements contained in mineral humic acid mainly include the following:
Carbon (C) content between 40% and 70% Oxygen (O) content between 25% and 45%
Hydrogen (H) content between 2% and 6% Nitrogen (N) content between 1 and 3%
Sulfur (S) content between 0-2%
Obviously, the carbon content is very high, which is why many manufacturers sell mineral humic acid as a carbon fertilizer.
The formation process of mineral humic acid
① The prototype of mineral source humic acid is the remains of animals and plants, mainly plant remains, under the earth’s crust. After transformation and decomposition by microorganisms, peat was first formed with extremely high moisture content. It contains humic acid, but it is difficult to extract and the cost is high. So although peat is a good raw material for humic acid extraction, it is not usually chosen.
② As time goes by, lignite is formed. When lignite is exposed to the air, weathered lignite is formed through physical or chemical weathering, which is also surface coal. Both lignite and weathered lignite belong to native humic acid.
③Lignite evolves over a long period of time to form bituminous coal or anthracite. Weathered coal is formed after weathering of bituminous coal and anthracite coal, which belongs to regenerated humic acid.
We can divide humic acid into black humic acid (above 5000D), brown humic acid (1000D-5000D), and fulvic acid (below 1000D) based on its chemical molecular weight. They are the three major components of mineral humic acid. The greater the molecular mass, the weaker the kinetic activity of the molecule. By dissolving mineral humic acid in water, its characteristics can be seen: it looks crystal clear after instant dissolution; after being left for a period of time, it will definitely stratify due to its large molecular weight.
