Huayuan fertilizer-efficiency potassium humate powder is a water-soluble concentrate that chelates nitrogen, phosphorus and potassium, keeping them in plant-available forms instead of letting them leach away or become locked in the soil. For coffee and rice farmers in Vietnam and Southeast Asia facing rising input costs, this powder raises the return on every kilogram of NPK applied while improving soil fertility.
Key Features
NPK Chelation: Forms stable complexes with nitrogen, phosphorus and potassium, reducing leaching and fixation losses in tropical soils.
Water Soluble Application: Mixes easily into fertigation tanks, knapsack sprayers and manual watering, suiting farms of every size.
Coffee Farming Optimised: Supports deeper rooting and more uniform cherry development in both young seedlings and mature coffee trees.
CEC Enhancement: Increases the soil's capacity to hold calcium, magnesium and potassium, improving fertility season after season.
Cost Efficiency: Higher fertiliser utilisation means the same yield with less chemical input, directly improving farm profitability.

Applications
Apply 10-20 kg per hectare through fertigation every 2-3 weeks during active growth, or broadcast 20-40 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.
