Humic Substances vs. Non-Humic Substances: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on February 1, 2024
Humic substances are complex organic compounds formed from plant and animal decay, crucial for soil health, while non-humic substances include simpler organic and inorganic matter not derived from humification.

Key Differences

Humic substances are composed of long-chain organic molecules resulting from the decay of organic matter. Non-humic substances encompass a broader range of organic and inorganic materials not derived from humification processes.
