Description
Natural Humic Acid Powder 100% Organic Reduces Soil Acidification Rice Paddy Farming
Huayuan natural humic acid powder is derived from high-grade weathered coal through a purely physical process of crushing, milling and sieving, with no chemical activation or synthetic additives. The resulting 100% organic powder preserves the full spectrum of native active groups, making it a dependable tool for reversing soil acidification in intensively cropped rice paddies across the Philippines and other Southeast Asian markets where continuous NPK application has steadily lowered soil pH.
Key Features
  • 100% Natural Source: physically processed weathered coal retains natural active groups without any chemical modification or synthetic binder.
  • Reduces Soil Acidification: buffers pH decline and restores a healthier root environment in paddies exposed to years of acid-forming fertilisers.
  • Rice Paddy Optimised: broadcast evenly before transplanting or direct seeding, the powder integrates with puddled soil and works through the whole season.
  • Microbial Stimulation: provides a carbon food source that boosts beneficial microbial populations, accelerating straw breakdown and nutrient cycling.
  • Improved Nutrient Retention: raises cation exchange capacity so ammonium and potassium stay in the root zone instead of leaching with flood water.

Applications
Broadcast 300-600 kg per hectare before land preparation and incorporate into the puddled layer. For vegetable rotations after rice, apply 450-900 kg per hectare in furrows or bands. Combine with microbial inoculants to speed up residue decomposition and improve fertiliser efficiency.
Do not exceed 2250 kg per hectare per season to avoid temporary oxygen depletion in saturated paddy soils.
Packaging & Quality Assurance
Supplied in 25 kg laminated kraft bags with inner PE liner, 1 ton jumbo bags, or customer-designated packaging. Every production batch is ISO 9001 certified and shipped with a certificate of analysis. We maintain a supply capacity of 50 tons per day and accept flexible L/C or T/T payment terms for B2B importers, distributors and plantation buyers across Southeast Asia and the Middle East.
