Pure Organic Humic Acid Granules 40-70% Humic Acid Water-Insoluble 2-5mm Particle Size for Soil Improvement
We employ a mechanical processing technique to produce pure humic acid granules from high-quality weathered coal sourced from our exclusive mining area. This process includes crushing, rotary disc agglomeration, and controlled heat treatment. No chemical modification occurs during the entire process, ensuring the complete preservation of the active functional groups. This results in unactivated granules with slow-release properties, suitable for a variety of agricultural applications.
These granules generate minimal dust, are impermeable, easy to handle, and provide long-lasting soil improvement. Due to their high density, they require mechanical incorporation into the soil after application.
