Product Description
Insoluble Organic Granule
Humic Acid Granular

Insoluble Humic Acid Round Granule Prill. Humic acid is formed by microbial degradation of dead biological substances, primarily leonardite. It consists of humic acid (HA), fulvic acid (FA), and humin (HM). Our products feature humic acid levels of 15%/50%/60% and NPK 14-0-1.

This product serves as a basal fertilizer and topdressing, enhancing the soil's carbon source and increasing microbial populations. It is suitable for field crops, organic farming, horticultural plants, landscapes, and lawns.

Frequently Asked Questions
What is humic acid?
Humic acid is a complex mixture created through microbial decomposition and geochemistry of plant remains. It is an organic matter that improves soil structure and nutrient absorption.
How does humic acid act on the soil?
It acts as an organic colloid that promotes the formation of soil aggregates, improves aeration and water permeability, and helps reduce the pH of saline-alkaline soils.
What are the basic functions of humic acids?
Key functions include adjusting soil pH, stimulating plant growth, increasing yield and quality, and neutralizing both acidic and alkaline soil conditions.
How does it interact with NPK fertilizers?
Humic acid has the ability to fix nitrogen, decompose phosphate, and fix potassium, which promotes better absorption of NPK by crops and provides a synergistic effect.
What is potassium humate?
Potassium humate is an important humic acid salt created when leonardite or lignite is treated with an alkaline substance like KOH.
What is the manufacturing process for high purity humate?
The process involves selecting raw leonardite, natural oxidation, chemical reaction with alkaline under high pressure, sedimentation to remove impurities, and finally centrifugal filtering and drying.
