Carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O) are three major greenhouse gases (GHGs) and all of them have increased sharply since 1750 due to human activities. Over a 100-year time period,the global warming potential (GWP) of CH 4 and N 2 O are 34 and 298 times greater than CO 2 , respectively [1]. Besides, N 2 O in the atmosphere is also playing an important role in damaging the stratospheric ozone layer [2]. Agricultural soil is an important source of anthropogenic GHG emissions due to a mass of nitrogen (N) fertilizer application [3]. Reducing agricultural soil GHG emissions has gained attention worldwide because of the GWP of GHGs and maintains the sustainbility of agricultural production [4]. Thus, there is an urgency to look for an effective method that can mitigate agricultural soil GHG emissions.
