Product Description

Humic Acid Granule
NPK Organic Fertilizer

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

  • Suitable for field crops and organic farming.
  • Ideal for horticultural plants, landscape, and gardens.
  • Improves crop yield and root development.
  • Acts as a slow and controlled release fertilizer.
  • Improves carbon source in soil and microbial populations.

Frequently Asked Questions

What is humic acid?
Humic acid is a complex mixture of organic matter created through the microbial decomposition and geochemistry of plant remains over millions of years. It is a key component of soil humus.
How does humic acid improve soil structure?
For sandy soil, it helps retain water and nutrients. For heavy/compact soil, it works with soil fungi to create a crumb structure for better oxygen and nutrient intake.
What are the basic functions of humic acids?
It adjusts soil pH, stimulates plant growth, increases yield and quality, reduces nitrate leaching into groundwater, and improves the effectiveness of pesticides.
What is the synergistic effect on NPK fertilizers?
Humic acid has the ability to fix nitrogen, decompose phosphate, and fix potassium, which promotes the overall absorption of NPK by crops.
How is potassium humate manufactured?
It is produced by selecting high-quality leonardite, crushing it into fine powder, reacting it with alkaline (KOH) under high pressure and temperature, and then filtering and drying the resulting liquid.
Is this product suitable for organic farming?
Yes, our humic acid granules are derived from natural minerals and are ideal for organic agricultural inputs and sustainable farming practices.
