productive soil can contain anywhere from 100 million to 1 billion individual bacteria
40000000
I've just been doing some research on this question and I found... "a teaspoon of rich garden soil can hold up to a billion bacteria, several yards of fungal filaments, several thousand protozoa and scores of nematodes"
how plentiful are bacteria in water and soil
Soil bacteria are the natural soil microorganisms that break down soil components into plant food.
they decomposed the materials in the soil
change the soil
they decomposed the materials in the soil
whenever there biodegradable materials in the soil the bacteria feed on them and turn them into useful chemicals which are good for the soil
bacteria can benefit conaminated soil because organic matter is formed.
Assimilation
Bacteria and fungi are types of organisms that are found in soil.
there are 1 billion bacteria in 1 gram of soil.
Denitrofying bacteria help to metabolize nitrogen so that they can use the it. These bacteria take available nitrogen from the soil, as opposed to nitrifying bacteria that increase available nitrogen in the soil.
