Fulvic Acid vs. Humic Acid

In this blog, we’ll explore the differences between fulvic acid and humic acid, including their chemical compositions, benefits, and how they are used in agriculture and health products.

Humic acid and fulvic acid are two common organic substances widely found in soil and water. The main differences between them lie in their structure, properties, and roles in different environments.

1. Structural Differences:

• Humic Acid: Composed mainly of polycyclic aromatic hydrocarbon compounds produced by microbial activity in soil, humic acid has a complex structure, including aromatic, aliphatic, and heterocyclic components. Its molecular weight is relatively large, typically ranging from tens of thousands to hundreds of thousands of Daltons. Humic acid exhibits strong adsorption capabilities, able to bind various cations and anions, including heavy metal ions. Additionally, it can regulate soil pH, promote plant growth, and enhance soil fertility.
• Fulvic Acid: Primarily derived from the decomposition of proteins in soil, fulvic acid features shorter carbon chains and higher aromaticity. Its molecular weight is smaller, usually around a few thousand Daltons. Fulvic acid has high solubility in aqueous solutions but is more dispersed in soil. It has minimal impact on soil pH but significantly influences the soil’s redox potential.

2. Environmental Roles:

• Humic Acid: Due to its larger molecular weight and complex structure, humic acid has strong adsorption capacity in soil, effectively stabilizing nutrients and preventing loss. It forms stable complexes with metal ions through chelation, reducing the bioavailability of heavy metals in soil. Humic acid also promotes plant growth and improves soil fertility.
• Fulvic Acid: With its lower molecular weight and higher aromaticity, fulvic acid exhibits better solubility and mobility in soil. It primarily affects the soil’s redox potential and has limited impact on soil pH.

3. Production Methods:

• Humic Acid: Produced through methods such as natural soil oxidation, high-temperature pyrolysis, or acid extraction. High-temperature pyrolysis is the most common approach, where soil samples are heated to enhance microbial activity, increasing humic acid yield.
• Fulvic Acid: Extracted via natural soil oxidation or acid leaching. Acid leaching is a frequent method, involving the use of acidic solutions to break down proteins in soil and release fulvic acid.

4. Applications:

• Humic Acid: Widely used in agriculture, forestry, and environmental protection. In agriculture, it boosts soil fertility and plant growth; in forestry, it serves as a fertilizer; and in environmental remediation, it treats wastewater by removing heavy metals and pollutants.
• Fulvic Acid: Due to its high solubility and mobility, fulvic acid is primarily employed in water treatment and environmental monitoring. It removes heavy metals and organic pollutants from water and detects organic content in soil and water bodies.

Though both are organic substances, humic acid and fulvic acid differ in structure and properties, leading to distinct production methods and applications. Humic acid excels in adsorption and pH regulation, while fulvic acid significantly impacts soil redox potential.
