An increasing number of people are using humic acid-based products to boost crop yields and efficiency. But do you know the relationship between Mineral Source Humic Acid and Mineral Source Fulvic Acid? And what exactly sets them apart? Let’s take a closer look.

Mineral Source Humic Acid is a natural organic macromolecular compound extracted from mineral sources such as lignite, weathered coal, or peat. It is formed from the remains of plants and animals through tens of millions of years of microbial decomposition and geochemical processes.
Mineral Source Fulvic Acid is a natural, biologically active organic substance extracted from mineral sources like weathered coal, lignite, or peat. It represents the component of humic acid with the lowest molecular weight and the highest water solubility.
The relationship between Mineral Source Humic Acid acid and Mineral Source Fulvic Acid:
Mineral Source Humic Acid is an organic mixture extracted from minerals such as lignite or weathered coal; fulvic acid is a specific component within this mixture, characterized by a smaller molecular weight and superior water solubility.

Differences between Mineral Source Humic Acid and Mineral Source Fulvic Acid:
1. Molecular weight: Mineral Source Humic Acid has a high molecular weight (10³–10⁶), while fulvic acid has a low molecular weight (10²–10³).
2. Water solubility: Fulvic acid is completely water-soluble and resistant to acids and bases, making it suitable for foliar spraying or drip irrigation. In contrast, potassium humate has poor resistance to hard water and is prone to flocculation or precipitation; it is primarily used for soil drenching (fertigation).
3. Speed of action: Fulvic acid is highly active; when applied to the root zone, it can break down within 2–3 days, with visible effects appearing in about a week. Humic acid, while slower to take effect, provides more long-lasting benefits for soil improvement.
How to choose between Mineral Source Humic Acid acid and Mineral Source Fulvic Acid:
1. For root promotion, enhanced stress resistance, and rapid results: Choose potassium fulvate (mineral-derived). It is ideal for the rooting stage or for helping crops withstand drought and cold.
2. For improving soil structure and enhancing water and nutrient retention: Choose potassium humate (mineral-derived). It is well-suited for the long-term conditioning of saline-alkali soils or compacted soil.
