Soil organisms are very important to improve soil fertility and maintain a natural balance between soil nutrient cycles, enzyme activities and biological transformation of complex substances. Typically, one gram of soil contains more than 90 million bacteria, which helps plants in nutrient uptake by converting them into forms that are available to the plants. People tend to think negatively of microbes because they are unaware of how important they are, even though they frequently behave as disease-causing agents. Similarly, the role of soil macroorganisms in improving soil structure and nutrient movement is equally significant. The use of biochar as an exuberant carrier of soil organisms in the soil ecosystem has been widely studied. Therefore, in this chapter, we will emphasis the types and functions of macro and microorganisms in the soil, the impact of biochar on soil organisms, nutrient cycling and enzyme activities.
