❓ Frequently Asked Questions
What is humic acid?
Humic acid is a complex mixture created through the microbial decomposition of animal and plant remains. It is a vital component of soil humus that improves soil structure and nutrient absorption.
What are the basic functions of humic acids?
It improves soil structure, adjusts pH values (neutralizing both acidic and alkaline soils), stimulates plant growth, and reduces nitrate leaking into groundwater.
How does humic acid interact with NPK fertilizers?
Humic acid has the ability to fix nitrogen, decompose phosphate, and fix potassium, which promotes the absorption of NPK by crops and provides a synergistic effect.
What is potassium humate?
Potassium humate is an important humic acid salt created by treating leonardite or lignite with an alkaline substance like KOH. It is highly effective for plant health.
How does humic acid improve soil structure?
For sandy soil, it helps retain water and nutrients. For heavy/compact soil, it works with fungi to create a crumb structure for better oxygen and nutrient intake by the roots.
What forms of humic acid are available?
We provide three main types through different drying processes: Flake type (rolling drying), Powder type (spray tower), and Crystal form (solar drying).
