Linking of microorganisms to CO_2, CH_4 and N_2O dynamics in Calamagrostis angustifolia rhizosphere soil
|
Abstract:
To understand the relationship between microbes and greenhouse gases, four soil cores dominated by Calamagrostis angustifolia were investigated to determine bacterial community as well as the production and consumption of methane (CH_4), carbon dioxide (CO_2) and nitrous oxide (N_2O) after 45 days incubation in an open area. Aerobic and anaerobic microorganisms were counted to evaluate the bacterial community, and the results suggested a significantly negative correlation between the aerobic and anaerobic. Meanwhile, there appeared to be obvious relationship between the bacterial community and CH_4, CO_2 and N_2O dynamics. The aerobic microbes were negatively related to CH_4 production, and positively related to CO_2 and N_2O production. The inverse relationship was observed between anaerobic microbe and the dynamics of these greenhouse gases.
