How can you show that microbes are present in the soil?

Answer:
Microbes in Soil
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.
The FDA or fluorescein diacetate test is used to indicate the activity of soil micro-organisms in field trials by detecting the presence of a broad range of enzymes released from living and dead microbes into soil.

Answer:
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.
