5 Types of Soil Microbes And What They Do For Plants
Beneficial soil microbes form symbiotic relationships with the plant. In fact, the plant will exert as much as 30% of its energy to the root zone to make food for microbes. In return those microbes not only protect the plant from stress, but also feed the plant by converting and holding nutrients in the soil.
What Are The Different Types Of Soil Microbes?
There are five different types of soil microbes: bacteria, actinomycetes, fungi, protozoa and nematodes. Each of these microbe types has a different job to boost soil and plant health.
Bacteria
Bacteria is the crucial workforce of soils. They are the final stage of breaking down nutrients and releasing them to the root zone for the plant. In fact, the Food and Agriculture Organization once said “Bacteria may well be the most valuable of life forms in the soil.”
Actinomycetes
Actinomycetes were once classified as fungi, and act similarly in the soil. However, some actinomycetes are predators and will harm the plant while others living in the soil can act as antibiotics for the plant.
Fungi
Like bacteria, fungi also lives in the rootzone and helps make nutrients available to plants. For example, Mycorrhizae is a fungi that facilitate water and nutrient uptake by the roots and plants to provide sugars, amino acids and other nutrients.
Protozoa
Protozoa are larger microbes that love to consume and be surrounded by bacteria. In fact, nutrients that are eaten by bacteria are released when protozoa in turn eat the bacteria.
Nematodes
Nematodes are microscopic worms that live around or inside the plant. Some nematodes are predators while others are beneficial, eating pathogenic nematodes and secreting nutrients to the plant.
