Abstract Biochar is a by product of agricultural biomass which is obtained from the Pyrolysis process under limited oxygen. It is very well utilized as soil amendments to improve the soil properties for a long period of time as compared to the other organic manures and soil amendments. In spite of the fact that the role of biochar on soil concoction properties is notable there is rare data about the effects of biochar on soil physical properties. The objective of the review is to gather all the information about the changes in soil primary nutrients and availability of these nutrients by the plant and highlight the areas where future investigation is required for better understanding of biochar application. After review it can be concluded that the application of biochar increased the soil ammonia oxidizing archea, ammonia oxidizing bacteria, phosphorus solubilising bacteria and K- dissolving bacteria. The potential systems behind these upgrades in soil physical properties by biochar application are high porosity, adsorptive nature of biochar, arrangement of territory to microorganisms and increment in all out soil natural carbon substance. However enhancements in soil physical properties by biochar expansion into the soil changes depend on soil type where biochar was applied, kind of biochar applied (based on feed stock and pyrolysis conditions and the quantity of biochar applied.
