Fertilizer-Efficiency Humic Acid Powder Boosts Nutrient Uptake Coffee Rice Farming
Huayuan fertilizer-efficiency humic acid powder is a water-soluble concentrate designed to maximise the return on every kilogram of NPK fertiliser applied. Its chelating structure holds nitrogen, phosphorus and potassium in plant-available forms, cutting nutrient losses and raising fertiliser utilisation rates. This makes it an economical soil management tool for coffee and rice growers in Vietnam and across Southeast Asia who face rising input costs and tightening margins.
Key Features
- Fertiliser Efficiency Booster: chelates nitrogen, phosphorus and potassium to prevent lock-up and leaching, raising the utilisation rate of applied fertiliser.
- Water Soluble Application: mixes easily into fertigation tanks, foliar sprays and manual watering, offering flexibility across different farm sizes.
- Coffee Farming Optimised: supports deeper rooting and more uniform cherry development in both young coffee seedlings and mature trees.
- CEC Enhancement: increases the soil's ability to hold calcium, magnesium and potassium, improving fertility and crop quality over successive seasons.
- Stress Resistance: helps coffee and rice plants tolerate dry spells and heat stress by improving root vigour and water-use efficiency.

Applications
Apply 10-20 kg per hectare through fertigation every 2-3 weeks during the active growing season, or broadcast 300-600 kg per hectare as a base dressing before planting. For coffee, place the powder around the drip line and water in thoroughly. For rice, apply before final puddling so the material is incorporated into the root zone.
