Detailed Product Description
Pure Organic Humic Acid Granules Produced - Used to Improve Water-Insoluble Soils
We employ advanced disc granulation technology to mechanically process carefully selected weathered coal, producing high-purity organic humic acid granules. This production method ensures the full retention of active functional groups while achieving slow-release properties, making it suitable for a variety of agricultural applications.
Manufacturing & Sourcing

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.

Supply Chain Transparency
Xinjiang's Fukang region supplies our Type I/II raw materials via company-controlled deposits, while Type III/IV incorporate Shanxi Province weathered coal.
Usage Protocols
Primary Soil Amendment (Pre-cultivation)
  • Grain cultivation: 300-600 kg/ha; till after spreading or integrate with compound fertilizers
  • Tree crops: 750-1,500 kg/ha; trench along canopy perimeter or use pit placement with soil covering
  • Vegetable systems: 450-900 kg/ha; furrow or localized application alongside organic amendments
Growth-Stage Supplementation
Apply 75-150 kg/ha during initial flowering or fruit development, ideally combined with potassium-rich fertilizers via banding or fertigation.
