“…Although water management has a large effect on N 2 O emission [e.g., Zheng et al , 2000], this pattern analysis can be expected to contain errors caused by the difficulty of determining the water regime, because details of water management (timing, number, and duration of drainage) were not described in many papers. In only seven papers among those reviewed were the seasonal changes in water depth for the entire cropping period reported [ Yagi et al , 1996; Cai et al , 1997, 1999; Suratno et al , 1998; Zheng et al , 2000; Ghosh et al , 2003; Nishimura et al , 2004]. In addition, details of fertilizer management (timing and application method for both basal and supplemental fertilizer application, N content of organic fertilizer) or the actual cropping period (date of transplanting and harvest) were not described in some papers.…”

[1] Rice cultivation is an important anthropogenic source of atmospheric nitrous oxide (N 2 O) and methane. We compiled and analyzed data on N 2 O emissions from rice fields (113 measurements from 17 sites) reported in peer-reviewed journals. Mean N 2 O emission ± standard deviation and mean fertilizer-induced emission factor during the rice-cropping season were, respectively, 341 ± 474 g N ha À1 season À1 and 0.22 ± 0.24% for fertilized fields continuously flooded, 993 ± 1075 g N ha À1 season À1 and 0.37 ± 0.35% for fertilized fields with midseason drainage, and 667 ± 885 g N ha À1 season À1and 0.31 ± 0.31% for all water regimes. The estimated whole-year background emission was 1820 g N ha À1 yr À1 . A large uncertainty remains, especially for background emission because of limited data availability. Although midseason drainage generally reduces CH 4 and increases N 2 O emissions, it may be an effective option for mitigating the net global warming potential of rice fields.

“…;Corradi et al 2005), whilst more CO 2 and CH 4 flux monitoring stations in tropical wetlands are needed. The few studies on GHG emissions from tropical peatlands have usually focused on non-CO 2 gases, such as methane and nitrous oxide, and in these, emission rates can be higher (Hadi et al 2000(Hadi et al , 2005 than rates from continuously irrigated rice grown on mineral soils (Husein et al 1995;Suratno et al 1998). These data are available for Indonesia, but comparable monitoring in South America, Africa and East Asia should be a high priority.…”

Humans utilise about 40% of the earth's net primary production (NPP) but the products of this NPP are often managed by different sectors, with timber and forest products managed by the forestry sector and food and fibre products from croplands and grasslands managed by the agricultural sector. Other significant anthropogenic impacts on Climatic Change (2008) the global carbon cycle include human utilization of fossil fuels and impacts on less intensively managed systems such as peatlands, wetlands and permafrost. A great deal of knowledge, expertise and data is available within each sector. We describe the contribution of sectoral carbon budgets to our understanding of the global carbon cycle. Whilst many sectors exhibit similarities for carbon budgeting, some key differences arise due to differences in goods and services provided, ecology, management practices used, landmanagement personnel responsible, policies affecting land management, data types and availability, and the drivers of change. We review the methods and data sources available for assessing sectoral carbon budgets, and describe some of key data limitations and uncertainties for each sector in different regions of the world. We identify the main gaps in our knowledge/data, show that coverage is better for the developed world for most sectors, and suggest how sectoral carbon budgets could be improved in the future. Research priorities include the development of shared protocols through site networks, a move to full carbon accounting within sectors, and the assessment of full greenhouse gas budgets.

“…Nitrification and denitrification compete with plant growth for NH 4 + -N and NO 3 − -N substrates (Suratno et al 1998). A new bio-fertilizer, arbuscular mycorrhizal fungi (AMF), has recently been used in rice cultivation (Solaiman and Hirata 1996;Zhang et al 2012;Ma et al 2013) because it can establish a symbiotic relationship with rice to promote nutrient uptake (Secilia and Bagyaraj 1994;Solaiman and Hirata 1995;Ortas 2012).…”

Arbuscular mycorrhizal fungi (AMF) can alter the dynamics of soluble nitrogen in paddy field soils by promoting nitrogen assimilation by rice. However, it is unknown whether this affects N 2 O emissions from rice paddies. This study was designed to assess the effects of AMF on N 2 O emissions by analyzing the relationships between AMF and the parameters affecting N 2 O emissions. Path analysis was used to quantitatively partition the direct and indirect effects of different parameters on N 2 O emissions. Results showed that N 2 O emissions were controlled by environmental pathways (transpiration, evaporation, and precipitation affecting soil water content) and biotic pathways (soluble nitrogen assimilation by the rice, which varies according to rice biomass). Under different water conditions, the contributions of the two pathways to N 2 O emissions varied strongly. During the flooding stage, the environmental pathways were dominant, but inoculation with AMF promoted the contribution of the biotic pathway to the reduction of N 2 O emissions. During the draining stage, the environmental pathways were dominant in the non-inoculated treatment, but inoculation made the biotic pathways dominant by increasing the biomass of rice. During the growing stage, N 2 O emissions from inoculated soil (17.9-492.9 μg N 2 O-N m −2 h −1 ) were significantly lower than those in noninoculated soil (22.1-553.1 μg N 2 O-N m −2 h −1 ; p<0.05). Consequently, inoculating with AMF has the potential for mitigating N 2 O emissions from rice paddies.
