There are several types of soil micro-organisms, including:
1. Bacteria: Bacteria are the most abundant type of micro-organisms in soil. They play a crucial role in nutrient cycling, decomposition of organic matter, and nitrogen fixation.
2. Fungi: Fungi are another important group of soil micro-organisms. They are involved in breaking down complex organic compounds, such as cellulose and lignin, and releasing nutrients for plants.
3. Protozoa: Protozoa are single-celled organisms that feed on bacteria, fungi, and other micro-organisms in the soil. They help regulate the populations of other soil organisms and contribute to nutrient cycling.
4. Algae: Algae are photosynthetic micro-organisms that can be found in soil, particularly in moist and sunny environments. They contribute to soil fertility by fixing carbon dioxide and producing organic matter.
5. Actinomycetes: Actinomycetes are a group of bacteria-like micro-organisms that have characteristics of both bacteria and fungi. They are important decomposers in soil and produce antibiotics that can suppress the growth of harmful pathogens.
6. Nematodes: Nematodes are microscopic worms that can be beneficial or harmful to soil health. Some nematodes feed on bacteria and fungi, while others are plant parasites that can damage crops.
7. Arthropods: Arthropods, such as mites, springtails, and beetles, are larger soil organisms that play a role in decomposition, nutrient cycling, and soil structure formation.
Overall, soil micro-organisms are essential for maintaining soil health and fertility, as they are involved in nutrient cycling, decomposition, and the suppression of harmful pathogens.

Bacteria:
- Aerobic bacteria: Require oxygen to survive. - Anaerobic bacteria: Thrive without oxygen. - Decomposers: Break down organic matter and release nutrients. - Nitrogen fixers: Convert atmospheric nitrogen into a usable form for plants. - Mycorrhizal bacteria: Form symbiotic relationships with plant roots, enhancing nutrient and water uptake.
Fungi:
- Mycorrhizal fungi: See "Mycorrhizal bacteria" above. - Saprophytic fungi: Decompose dead organic matter, releasing nutrients. - Parasitic fungi: Attack and feed on living plants or other organisms.
Protozoa:
- Amoebas: Single-celled organisms that move and feed by engulfing prey. - Ciliates: Single-celled organisms with hair-like structures for movement. - Flagellates: Single-celled organisms with whip-like structures for movement.
Nematodes:
- Bacterivores: Feed on bacteria. - Fungivores: Feed on fungi. - Predators: Feed on other nematodes or protozoa.
Viruses:
- Bacteriophages: Infect and kill bacteria. - Fungal viruses: Infect and kill fungi.
Other Micro-organisms:
- Algae: Photosynthetic organisms that provide food and oxygen. - Archea: Ancient single-celled organisms that can thrive in extreme environments. - Actinomycetes: Filamentous bacteria that decompose organic matter and produce antibiotics.
