Description

Fulvic Acid is a naturally occurring, low-molecular-weight organic compound extracted from weathered lignite and humic-rich deposits. It belongs to the humic substance family and is distinguished from humic acid by its much smaller molecular size, higher oxygen content, and superior water solubility at all pH levels. This 95% water-soluble powder form provides a highly concentrated, easy-to-use source of active fulvic acid for agricultural, industrial, and environmental applications.

The unique chemical structure of fulvic acid — rich in carboxylic, phenolic, and hydroxyl functional groups — gives it outstanding cation exchange capacity and natural chelating ability. When applied to soil, it complexes with essential nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, iron, zinc, and copper, keeping them available to plant roots and reducing nutrient loss through leaching and fixation. As a result, fertilizer efficiency is improved, and plants can access a steady, balanced supply of nutrition throughout the growing cycle.

In the soil, fulvic acid acts as a powerful soil conditioner. It improves soil structure by promoting the formation of stable aggregates, which enhances aeration, water infiltration, and root penetration. It also buffers soil pH, supports beneficial microbial activity, and increases the soil's water-holding capacity, making it especially valuable in sandy, saline, alkaline, and degraded soils. Regular application helps rebuild soil organic matter and long-term fertility.

For plants, fulvic acid stimulates seed germination, promotes vigorous root development, and enhances the uptake of water and nutrients. It also improves plant resistance to environmental stress such as drought, high temperature, and transplant shock. Because it is fully water soluble and compatible with most fertilizers, it can be applied through drip irrigation, foliar spraying, fertigation systems, or as a seed treatment, and it works well in combination with NPK fertilizers, micronutrients, and biostimulants.

Beyond agriculture, this product is widely used in livestock feed as a digestive and immunity-supporting additive, in industrial formulations such as drilling fluids and water treatment agents, and as a raw material for organic and biological products.

Quality assurance: our fulvic acid is produced under strict process control, with consistent content, uniform particle size, and stable solubility. It is free of heavy-metal contamination within regulatory limits and contains no synthetic additives. Each batch is tested before shipment and accompanied by a Certificate of Analysis. Packaged in moisture-proof, food-grade materials, the product has a long shelf life when stored in a cool, dry, and well-ventilated area away from direct sunlight and moisture. Please keep the packaging sealed after use and avoid contact with eyes; in case of contact, rinse thoroughly with clean water.

With its proven performance in improving soil health, nutrient efficiency, and crop quality, Fulvic Acid 95% is a reliable choice for distributors, formulators, and growers seeking a high-quality, cost-effective organic input.

ECHEMI Editorial Reference

Fulvic acids refer to collectively of a set of organic acids, natural compounds, and components of the humus [which is a fraction of soil organic matter].
[1]
They share similar structure with humic acids, with differences being the carbon and oxygen contents, acidity, and degree of polymerization, molecular weight, and color.
[2]
Fulvic acid remains in solution after removal of humic acid from humin by acidification
[3, 4]
. Humic and fulvic acids are mainly produced
