Soil represents a medium or substrate in which numerous microorganisms live and bring about a great variety of processes which are responsible for continuation of the cycle of life in nature. The numerous living forms spend all or part of their life in soil ranging from sub microscopic forms to the lower animal forms. With the growing recognition of the numerous processes carried out by the microorganisms in the soil there gradually emerged a branch of microbiology, which came to known as Soil microbiology. It is a branch of soil science concerned with soil inhabiting microorganisms and their functions and activities.
