Humic Acid Granule Natural Organic Fertilizer Additive Improving Soil Health and Promoting Sustainable Farming Methods
Our company uses high-quality weathered charcoal mined from our own mines and employs mechanical processing technology to produce high-purity humic acid granules. This process includes crushing, rotary disc agglomeration, and controlled heat treatment. No chemical modification is performed throughout the entire production process, ensuring the complete preservation of active functional groups. Ultimately, we obtain slow-release, non-reactive humic acid granules suitable for various agricultural applications.
These granules produce very little dust, are impermeable to water, are easy to handle, and have a long-lasting soil-improving effect. Due to their high density, they must be mechanically mixed into the soil after application.
