“…Our estimates are consistent over the three seasons and comparable to previously published rates from rice fields from temperate countries. Reports from continuously irrigated systems include the following values of kg CH 4 ha −1 : 634 (Hadi et al, 2010); 250 (Cicerone et al, 1992); 112-404 (Schütz et al, 1989); 200-500 (Gutierrez et al, 2013) from Japan, California, Italy and South Korea, respectively. Two continuously irrigated systems (direct-seeded, delayed flood) similar to ours have reported values of 270 kg CH 4 ha −1 (Rogers et al, 2012) and 340-423 kg CH 4 ha −1 (Moterle et al, 2013) from rice fields in Arkansas, USA, and southern Brazil, respectively.…”

, 55 % lower compared to CF30, while no differences in nitrous oxide emissions were observed between treatments (p > 0.05). No yield differences between irrigation systems were observed in two of the rice seasons (p > 0.05) while AWDI promoted yield reduction in one of the seasons (p < 0.05). When rice yield and greenhouse gases (GHG) emissions were considered together, the AWDI irrigation system allowed for lower yield-scaled total global warming potential (GWP). Higher irrigation water productivity was achieved under AWDI in two of the three rice seasons. These findings suggest that AWDI could be an option for reducing GHG emissions and increasing irrigation water productivity. However, AWDI may compromise grain yield in certain years, reflecting the importance of the need for fine tuning of this irrigation strategy and an assessment of the overall tradeoff between relationships in order to promote its adoption by farmers.

“…5). Also, although CH 4 emissions were responsive to variety-specific traits, no uniform pattern emerged (Gutierrez et al, 2013;Satpathy et al,1998;. These results suggest that aboveground plant traits may not be the primary factor controlling CH 4 emission, despite their potential effect on CH 4 transport from soil.…”

“…Some researchers found that the CH 4 emission was positively and significantly correlated with plant biomass and grain yield (Lou et al, 2008), as well as with plant height, tiller number and leaf area index (Ding et al, 1999;Gogoi et al, 2005;Wang et al, 1997). However, other scientists found that plant properties (including tiller number, shoot length and weight, and root weight) were not associated or even negatively associated with the CH 4 emission (Gutierrez et al, 2013;Sigren et al, 1997;Watanabe et al, 1995). Therefore, no consensus has so far emerged about the relationships between rice plant characteristics and the CH 4 emission.…”

“…This suggests the possibility for genetic improvement of rice varieties to reduce CH 4 emission without compromising rice yields (Gogoi et al, 2008;Gutierrez et al, 2013;Jiang et al, 2013). Therefore, identification of morphological and physiological parameters of rice plants that are related to the CH 4 emission is significant for new variety selection for high yield with low CH 4 emission.…”

“…It should be noted that we examined anaerobic CH 4 oxidation in our study which was often ignored in CH 4 oxidation. The PLFAs method cannot differentiate the methanogenic biomass, but previous studies found that CH 4 efflux was positively correlated with methanogenic biomass (Radl et al 2007;Gutierrez et al 2013;Narvaez et al 2013;Urbanov a et al 2013) but negatively with methanotrophic biomass (Levine et al 2011;Nazaries et al 2013). In fact, the CH 4 efflux at the airÀwater interface is the balance between CH 4 production in the sediment and CH 4 oxidation in the process of transport from the sediment to the atmosphere.…”

Lake sediments accumulate large amounts of greenhouse gases (GHGs) through microbial decomposition of organic matter. To investigate the relationship between microbial biomass and GHG effluxes, we conducted a large-scale survey in Poyang Lake, the largest freshwater lake in China. We measured GHG effluxes using the floating chamber method at 42 sampling sites for three days and also measured microbial biomass using the phospholipid fatty acids (PLFAs) method. We found that the methane emission rate was positively and linearly related to total microbial biomass, anaerobic biomass, and anaerobic biomass excluding anaerobic methanotrophs. In addition, nitrous oxide efflux normalized to the amount of organic carbon in the sampling sediment (N 2 O/SOC) was significantly correlated with fungal biomass and the ratio of fungal biomass to total microbial biomass. But there were no significant relationships between the CO 2 and CH 4 normalized efflux in the sampling sediment and the biomasses of microbial groups. These results suggest that we could manage GHG emissions by considering the factors regulating microbial biomass in the lake sediments.
