"Methane (CH4) is 25 times more effective than carbon dioxide at trapping infrared radiation over a 100 year period and is the second most significant source of radiative forcing in Earth's atmosphere. The largest biological sink is through oxidation by aerobic soil microbes, termed methanotrophs, which can be impacted by land management such that both methanotroph diversity and CH4 consumption decrease by 70% when forests are converted to row-crop agriculture. In this study, the potential of a methanotrophic soil inoculum to enhance methane consumption was investigated in both microcosm and pilot-scale field experiments."--From abstract.
