Detailed Product Description


Pure organic humic acid granules-disc granulation process


1.Manufacturing & Sourcing

We mechanically process premium weathered coal from our exclusive mining concessions into pure humic acid granules through crushing, rotary disc agglomeration, and controlled thermal treatment. Zero chemical modification ensures complete preservation of active functional groups, delivering unactivated particles with extended-release properties for versatile agricultural deployment.
Featuring low-dust granular physics, these water-resistant particles facilitate easy handling and prolonged soil enhancement. Due to their density, mechanical soil incorporation is necessary post-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.
2.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.
3.Critical Precautions
  • Not a standalone fertilizer; mandatory combination with NPK sources
  • Application ceiling: 2,250 kg/ha to avoid anaerobic soil conditions
  • Enhanced performance when paired with beneficial microbial formulations
