Crop residue management becomes the challenging issue to farmers for balancing between the economic and sustainable environment. Though burning is the easiest way of destroying the crop waste it not only causes drastic changes in green house gas but also large amount of nutrients are removed from soil by plants. Hence the technique which protects the environment along with enhancing soil quality is needed. Therefore pyrolysis of crop residue can become an alternate technique against past strategies. The heterogeneous characteristics of the biochar can be produced through the pyrolysis process and that would be employed as a soil amendment. The biochar application ameliorates the problems which persist in soil and enhance the crop production in environmentally sound way. And largely involved in the carbon sequestration thereby sustain the soil quality. However there is lack of information available on effects of long term application of biochar and durability of persistence in soil. Thus in those things made to review on brief account of biochar such as, biochar production, characteristics, impacts on soil properties, crop growth, reduction of green house gases and heavy metal remediation. Moreover, in this review discusses about what are all the challenges and future trust in the application of biochar. So, the deep understanding on biochar and its interaction with soil can bridge the gap prevailed in the scientific field and crop improvement.
