Water-Soluble Humic Acid Powder 70% Fertigation Grade Palm Oil Plantation Soil Amendment
Huayuan water-soluble humic acid powder is produced from premium weathered coal mined in Ningxia, China, and processed into a fine 60-80 mesh powder that dissolves completely in irrigation water without residue. This fertigation-grade formulation delivers humic substances directly to the root zone through drip, sprinkler and pivot systems, making it the preferred choice for large palm oil plantations across Indonesia and Southeast Asia that rely on efficient water and nutrient management.
Key Features
- Complete Water Solubility: The fine powder dissolves fully in water without clogging emitters, allowing precise dosing through automated fertigation equipment.
- Fertigation Grade Purity: Uniform 60-80 mesh particles keep drip lines and sprinkler nozzles clean while delivering humic substances straight to the root zone.
- Palm Oil Plantation Optimised: Improves nutrient uptake in mature oil palm, supporting higher fresh fruit bunch yields and healthier frond development.
- Powerful Chelating Action: Binds micronutrients such as zinc, iron and manganese, preventing them from being locked up in tropical clay soils.
- Fast Acting Response: Soluble humic acid becomes available to soil microbes within days of application, accelerating soil improvement and root response.

Applications
Apply through fertigation at 15-30 kg per hectare per application, mixed with compound NPK solutions during the main fertiliser schedule. For palm oil nurseries, use 5-10 kg per hectare in the irrigation water every two weeks. The powder can also be dissolved in a stock tank and injected through venturi or pump systems, and is compatible with most water-soluble fertilisers used in plantation agriculture.
