Technology Focus | Redefining Nutrient Efficiency with Small-Molecule Humic Acid Technology
05 - Dec - 2025 By: BLUESIS
In today's pursuit of green and efficient agricultural development, the value of humic acid products is widely recognized. However, not all humic acids possess equal efficacy. Since their launch, the core humic acid products from Bluesis have consistently reshaped industry standards for high-efficiency humic acid, thanks to their breakthrough advantages in molecular weight, functional groups, and activity indicators.
Breaking Through Bottlenecks: Why Small Molecules Matter
Traditional humic acids have large molecular weights, typically ranging from hundreds of thousands to millions of Daltons (Da), making them difficult for plants to absorb directly and resulting in low utilization rates. The core technological breakthrough of Bluesis lies in its unique physico-chemical activation process, which precisely controls the humic acid molecular weight in the product below 5000 Da. These small molecular fragments (primarily fulvic acid) offer two key advantages:
1.Faster Absorption: Their smaller size allows rapid entry through crop root systems and cell membranes, enabling direct participation in physiological metabolism.
2.Higher Bioactivity: They provide more surface reaction sites.

| Note: Over 90% of the humic acid molecules obtained from optimization using the two different agents have a molecular weight below 5000 Da. | Note: By replacing traditional turbidimetry with precision separation technology and designing meticulously based on function and user requirements, precise separation of carboxyl and phenolic hydroxyl groups in humic acid can be achieved, thereby yielding more targeted graded products. |
Five Functional Groups: The Synergistic "Power Core"
The humic acid product is rich in five key active functional groups, including carboxyl and phenolic hydroxyl groups. These functional groups act like the product's "intelligent arms," enabling it to:
1.Efficiently Chelate: Firmly bind medium and trace elements in the soil, forming easily absorbable complexes and effectively preventing nutrient fixation.
2.Improve Soil: Interact with soil particles to promote aggregate formation and alleviate compaction.

Gold Standard E4/E6=7.32: Scientifically Verified High Activity
The E4/E6 ratio is an internationally recognized key indicator for assessing humic acid quality and molecular size. A higher ratio indicates a greater proportion of small-molecule fulvic acid and stronger biological activity. Authoritative testing confirms that Bluesis's humic acid product achieves an E4/E6 ratio as high as 7.32. This figure far exceeds that of ordinary humic acids, providing scientific validation for its inherently high activity.
Combining Immediate & Long-Lasting Effects: Achieving 1+1>2 Field Performance
Based on its unique molecular structure, the product successfully addresses the common pain points of traditional products being either "slow-acting" or "short-lasting."
1.Immediate Effect: The small-molecule characteristics ensure rapid stimulation of root development and alleviation of stress, resulting in a noticeable "quick revival" effect in crops.
2.Long-Lasting Effect: The activated humic acid continues to function as a soil conditioner, regulating the micro-ecology, and improving water and nutrient retention for more sustained results.
Through the precise regulation of its molecular structure, Bluesis has redefined the standard for high-efficiency humic acid. It is not merely a product, but a technological embodiment of the company's Plant Health + Nutrition philosophy, aimed at providing growers with truly efficient and sustainable cultivation solutions.
