“…However, emissions were smaller (20-40 kg ha −1 ) compared to that reported from many other countries such as Philippines (100-150 kg ha −1 ) (Corton et al, 2000) and Japan (150-200 kg ha −1 ) (Yagi et al, 1996). Lower CH 4 emission from Indian rice paddies compared to that of other countries could be due to 1) lower soil organic C status, 2) high percolation rate of sandy loam soils, which allows to leach substantial amount of DOC to lower soil profiles, 3) lower yield of rice with smaller rhizodeposition and 4) limited amount of organic residue recycling in soil.…”

Abstract. The Denitrification and Decomposition (DNDC) model was evaluated for its ability to simulate methane (CH 4 ), nitrous oxide (N 2 O) and carbon dioxide (CO 2 ) emissions from Indian rice fields with various management practices. The model was calibrated and validated for field experiments in New Delhi, India. The observed yield, N uptake and greenhouse gas (GHG) emissions were in good agreement with the values predicted by the model. The model was then applied for estimation of GHG emissions from rice fields in India using a newly compiled soil/climate/land use database. Continuous flooding of rice fields (42.25 million ha) resulted in annual net emissions of 1.07-1.10, 0.04-0.05 and 21.16-60.96 Tg of CH 4 -C, N 2 O-N and CO 2 -C, respectively, with a cumulated global warming potential (GWP) of 130.93-272.83 Tg CO 2 equivalent. Intermittent flooding of rice fields reduced annual net emissions to 0.12-0.13 Tg CH 4 -C and 16.66-48.80 Tg CO 2 -C while N 2 O emission increased to 0.05-0.06 Tg N 2 O-N. The GWP, however, reduced to 91.73-211.80 Tg CO 2 equivalent. The study suggested that the model could be applied for estimating the GHG emissions and the influences of agronomic management, soil and climatic parameters on the GHG emissions from rice fields in India.

Abstract. To assess contribution of multiple environmental factors to carbon exchanges between the atmosphere and forest soils, four old-growth forests referred to as boreal coniferous forest, temperate needle-broadleaved mixed forest, subtropical evergreen broadleaved forest and tropical monsoon rain forest were selected along eastern China. In each old-growth forest, soil CO 2 and CH 4 fluxes were measured from 2003 to 2005 applying the static opaque chamber and gas chromatography technique. Soil temperature and moisture at the 10 cm depth were simultaneously measured with the greenhouse gas measurements. Inorganic N (NH + 4 -N and NO − 3 -N) in the 0-10 cm was determined monthly. From north to south, annual mean CO 2 emission ranged from 18.09 ± 0.22 to 35.40 ± 2.24 Mg CO 2 ha −1 yr −1 and annual mean CH 4 uptake ranged from 0.04 ± 0.11 to 5.15 ± 0.96 kg CH 4 ha −1 yr −1 in the four old-growth forests. Soil CO 2 flux in the old-growth forests was mainly driven by soil temperature, followed by soil moisture and NO

“…In the 2002 fields, CH 4 fluxes tended to decrease with increasing urea application ( Corton et al, 2000;Sass et al, 1992;Wassmann et al, 2000;Yagi et al, 1996;Zheng et al, 2000]. Under continuous flooding, some recognizable CH 4 flushes was observed over the whole season, particularly when crop residues were incorporated ( Figure 1a).…”

[1] A 3-year field experiment was conducted to simultaneously measure methane (CH 4 ) and nitrous oxide (N 2 O) emissions from rice paddies under various agricultural managements including water regime, crop residue incorporation, and synthetic fertilizer application. In contrast with continuous flooding, midseason drainage incurred a drop in CH 4 fluxes while triggering substantial N 2 O emission. Moreover, N 2 O emissions after midseason drainage depended strongly on whether or not fields were waterlogged due to intermittent irrigation. Urea application tended to reduce CH 4 emissions but significantly increased N 2 O emissions. Under a water regime of flooding-midseason drainagereflooding-moist intermittent irrigation but without water logging (F-D-F-M), both wheat straw and rapeseed cake incorporation increased CH 4 emissions by 252%, and rapeseed cake increased N 2 O by 17% while wheat straw
