Certain bacteria is nitrogen-fixing. That is, bacteria can take the Nitrogen in the air and converts it into a form that plants can take in as nutrients. Without this bacteria, soil erosion would occur due to the lack of nutrients. Legumes such as soybeans have a symbiotic relationship with this nitrogen-fixing bacteria.

Bacteria breaks things down so as to promote decay in the soil. Then the nutrients ( minerals ) are available for consumption / absorbtion. This allows growth in plants.

Bacteria is a natural decomposer in nature. So, it breaks down dead matter into nutrients for the soil to use.

trees drop their leaves and the leaves decompose with the help of bacteria and micro organisms ,the earth worms eat the rotten mulch and their excrements and that of micro organisms is what the black top soil in forrests is made up from
,other soils as well but the trees have since gone
