5 Types of Soil Microorganisms

Have you ever stopped to think about the bustling community that exists right beneath your feet? Soil microorganisms play a crucial role in maintaining the health and fertility of our lawns, gardens, and ecosystems. With the lawn care from Nature’s Select Triangle, you can support these five types of soil microorganisms commonly found in North Carolina soils.

1. Bacteria

Bacteria are among the most abundant soil microorganisms. They play a vital role in breaking down organic matter and releasing nutrients that plants can absorb. Some bacteria also form symbiotic relationships with plants, helping them fix nitrogen from the air. In North Carolina soils, you are likely to find species, such as Rhizobium and Azotobacter, which contribute to the health and productivity of your lawn.

2. Fungi

Fungi are another important group of soil microorganisms that help decompose organic matter and improve soil structure. Mycorrhizal fungi form mutually beneficial relationships with plant roots, aiding nutrient uptake and water absorption. North Carolina soils are home to a diverse array of fungi, including species like Penicillium and Trichoderma, which can enhance plant growth and protect against diseases.

3. Protozoa

Protozoa are single-celled organisms that feed on bacteria, fungi, and other microorganisms in the soil. By preying on these microbes, protozoa help regulate their populations and maintain a healthy balance in the soil ecosystem. Some species of protozoa also release nutrients through their waste products, making them available for plant uptake.

4. Nematodes

Nematodes are tiny roundworms that can benefit or harm plants depending on their feeding habits. Predatory nematodes feed on other soil organisms, like bacteria and fungi, helping control pest populations. Plant-parasitic nematodes, on the other hand, can damage plant roots and reduce crop yields if left unchecked.

5. Actinomycetes

Actinomycetes are filamentous bacteria that resemble fungi in appearance but belong to the bacterial kingdom. These microorganisms produce enzymes that break down tough organic matter, like cellulose and chitin, contributing to nutrient cycling in the soil. Actinomycetes play a crucial role in decomposing plant residues and improving soil fertility in North Carolina soils.
