To review:

The ability of several microbes to fix the free atmospheric nitrogen and the dependency of others on the availability of derivatives of nitrogen. Also, mention the environmental factors influencing each category.

Introduction:

Nitrogen is a vital limiting factor in plant growth and development. It is a major component that is present in chlorophyll and amino acids. Plants cannot use the free atmospheric nitrogen, but can use the reduced forms of nitrogen. There are various microbes in the environment that are associated with the reduction of nitrogen so that it can be utilized by the plants.
