Methane emission from soil-plant systems

Methane (CH<inf>4</inf>) emission data showed large temporal and spatial variation ranging from 0 to 249.3 mg CH<inf>4</inf> m<sup>−2</sup> h<sup>−1</sup>. Results indicated that the highest CH<inf>4</inf> flux rate was obtained in growth seasons. The polyculture system and Zizania latifolia has the higher potential of global warming. Methane fluxes have a remarkable seasonal and temporal variability in vegetation systems resulting from variation in the environmental parameters regulating the microbial processes. Methane emission from soil-plant systems was correlated with microbial activities. Methanogens and Methanotrophs contributed to the CH<inf>4</inf> generation and consumption, respectively.
