No, humus is not bacteria. Humus is a complex, dark-colored organic substance formed in soil by the decomposition of plant and animal matter. This decomposition process is carried out by various soil organisms, including bacteria, fungi, and earthworms. Humus itself is the end product of their activity, not a living organism.
What is Humus?
Humus is the dark, amorphous organic matter found in soil. It's created through the breakdown of dead plants and animals. This decomposition process is a crucial part of the nutrient cycle in soil.

- Role of Microorganisms: Microorganisms such as bacteria and fungi are essential in the humification process, breaking down complex organic molecules into simpler ones. [Source: Lallemand Plant Care, Phoslab Environmental Laboratories]
- Humus as a Habitat: Humus provides a habitat and food source for beneficial soil organisms. [Source: Nutri-Tech Blog]
- Ammonia-Oxidizing Bacteria's Role: Even the formation of humus can be influenced by the activity of ammonia-oxidizing bacteria, altering the bacterial community's function and impacting nitrogen conversion in the soil. [Source: ScienceDirect]
The key takeaway is that while bacteria are involved in the creation of humus, humus itself is not a bacterium or a type of bacteria. It is the result of biological activity within the soil.
