Mineral-derived humic acid is a natural organic substance primarily sourced from soil, rivers, lakes, and other natural environments. It is a high-molecular-weight compound formed through the decomposition and transformation of plant and animal residues under microbial action. Rich in nutrients and biologically active, mineral-derived humic acid can be classified into various categories based on its origin, structure, function, and applications.
1. Classification by Origin
Mineral-derived humic acid mainly originates from the following sources: (1) Soil Humic Acid: Formed from the decomposition of plant and animal residues in soil under microbial action, including peat soil humic acid, lignite humic acid, and weathered coal humic acid. (2) River Humic Acid: Derived from the decomposition of residues in rivers, such as river peat soil humic acid and river lignite humic acid. (3) Lake Humic Acid: Produced from residues in lakes, including lake peat soil humic acid and lake lignite humic acid. (4) Marine Humic Acid: Formed from marine residues, such as marine peat soil humic acid and marine lignite humic acid.
2. Classification by Structure
The structure of mineral-derived humic acid is complex, comprising the following components: (1) Aromatic Compounds: Including benzene, toluene, xylene, etc., which are the main components with antioxidant, antibacterial, and antiviral activities. (2) Aliphatic Compounds: Such as fatty acids and glycerides, providing functions like lubrication, moisture retention, and anti-aging. (3) Carbohydrates: Including sugars, starch, and cellulose, serving as primary energy sources that promote plant growth and improve soil fertility. (4) Proteins: Comprising amino acids, peptides, and enzymes, which regulate plant growth and enhance disease resistance.
3. Classification by Function
