| Abstract: | Nowdays, agricultural is closely linked to the global climate changes exploring the way to reduce agricultural greenhouse gas emissions, and sequester soil carbon has become a hot issue in the current agricultural and environmental research. This paper aims at exploring the possible ways to develop low-carbon agriculture, which is characterized by low energy, low emissions and low pollution, by using biomass pyrolysis technique. Firstly, the definition, characteristics of low-carbon agriculture is described, and the ways to realize it are also discussed. Secondly, the basic characteristics of biochar, and its value in terms of agriculture and environment are discussed. Mostly, the possible modes of biochar integrated system are emphatically discussed in the context of low-carbon agriculture. Finally, the challenges exited nowadays are pointed out. |
