Pure Organic Humic Acid Granules 40-70% Humic Acid Water-Insoluble 2-5mm Particle Size for Soil Improvement

Our pure organic humic acid granules are manufactured through mechanical processing of premium weathered coal using advanced disc granulation technology. This process ensures complete preservation of active functional groups while delivering extended-release properties for versatile agricultural applications.

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.

Xinjiang's Fukang region supplies our Type I/II raw materials via company-controlled deposits, while Type III/IV incorporate Shanxi Province weathered coal.

Apply 75-150 kg/ha during initial flowering or fruit development, ideally combined with potassium-rich fertilizers via banding or fertigation.
