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.
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.
