Fertile soil contains the nutrients in a readily available form that plants require for growth.
The roots of the plant act as miners moving through the soil and bringing needed minerals into the plant roots. However, the nitrogen in the atmosphere is not in a form that plants can utilize. These plants tend to have root nodules in which the nitrogen-fixing bacteria live. Not all bacteria utilize the above route of nitrogen fixation. Many that live free in the soil, utilize other chemical pathways.
