Plants need nitrogen in order to grow. Nitrogen is abundant in the earth's atmosphere, but plants cannot use it in that particular form (nitrogen gas). Certain bacteria which reside on some plant roots are able to change atmospheric nitrogen into a form that plants can use (ammonia).
<span>Natural nitrogen fixation; An important part of the natural nitrogen cycle were nitrogen gas (N2) in the atmosphere is converted into ammonia (NH3) in in the ground. Some bacteria (diazotrophs), both free living in the soil and in symbiosis with root nodules of some plants, use enzymes (nitrogenazes) to convert the nitrogen into a form that can be used by living organisms.Hope this helps :/
