Roles of biomass-derived black carbon in soil and environment ecosystem: A review

As the global warming intensifying, Climate change has become an important environmental problem which has caused great concern around the world. Reducing the effects of greenhouse gases to the climate and ecosystem and stocking more carbon sequestration are the solved critical problems which government and scientist around world must face. As a potential mean of solving the emission of greenhouse gases, biochar (biomass-derived black carbon) has gradually become one of the most important research issues. All the paper researches around world show that biochar plays a powerful function and important role in soil amendment and environmental system. Biochar can be used as a soil amendment to improve soil structure, soil quality and increase crop production etc. The biochar approach provides a potential powerful solution: it allows us to sequestrate more carbon as well as reducing more pollutions of greenhouse gases from the environment and it will change the way of C cycles in the ecological system. As a soil ameliorant, it could increase the carbon stock sequestrations in soil all over the world. It provides the important solution to deal with the climate change problems. This paper reviews the latest important research, and offers the further research prospects. It aims to illustrate the important function of biochar in the soil and ecosystem, and offer the references for the further scientific biochar research which benefits for the further requiring study.
