Water-Soluble Potassium Humate Powder 95% Fertigation Grade Palm Oil Plantation Nutrient
Huayuan water-soluble potassium humate powder is a black-brown, fine-mesh fertiliser raw material with 95-100% water solubility, produced from premium weathered coal and activated potassium hydroxide. It delivers both humic acid and soluble potassium in a single application, making it the ideal choice for fertigation programmes on palm oil plantations across Indonesia and Southeast Asia, where efficient nutrient delivery directly affects fresh fruit bunch yield.
Key Features
- Complete Water Solubility: 95-100% of the powder dissolves in water without residue, allowing precise dosing through drip and sprinkler fertigation systems.
- Dual Nutrient Supply: supplies humic acid and soluble potassium together, feeding soil biology while meeting the crop's potassium demand.
- Fertigation Grade: uniform 60-80 mesh particles keep emitters and nozzles clean, reducing maintenance and downtime in plantation irrigation networks.
- Chelating Power: binds zinc, iron, manganese and other micronutrients, preventing them from being locked up in tropical clay soils.
- Palm Oil Optimised: supports healthier fronds, better root development and steadier bunch production in both mature and young oil palms.

Applications
Apply 15-30 kg per hectare through fertigation every 2-3 weeks during the main growing season, dissolved in the irrigation water together with compound NPK solutions. For oil palm nurseries, use 5-10 kg per hectare in the water every two weeks. The powder is compatible with most water-soluble fertilisers and can be injected through venturi, pump or gravity-drip systems without clogging.
