“…Many studies reported that the paddy rice fields have significantly lower N 2 O fluxes than uplands, especially in the flooding period [24,25]. The N 2 O emission from paddy rice during the flooding period was near zero or negative value [18,26]. Our results were consistent with those previous reports and N 2 O flux in flooding soils was near negligible (Figure 1).…”

To investigate N 2 O emissions from intensive manure managements, eight farmer's fields covering paddy rice and uplands cropping systems in a livestock watershed of central Japan has been selected. The manure was popular applied with PIAF (Ploughing Immediately after Fertilization), FKSSL (Fertilizer Keeping on the Surface Soil for a Longer Time) and only applied in winter fallow season for paddy rice under the application rate of 200-800 kg N ha -1 yr -1 . Field gas samples were conducted by static chamber method. The result showed that N 2 O flux varied from 0 to 1607 µg N m -2 h -1 in upland crop systems and from 0 to 924 µg N m -2 h -1 in paddy fields. And the annual emission ranged from 1.91-9.26 kg N ha -1 yr -1 accounting for 0.48 ± 0.41% of input N in uplands and 1.28-1.91 kg N ha -1 yr -1 accounting for 0.43 ± 0.27% of input N in paddy rice, respectively. In rice/fallow system, more N 2 O emitted and the emission factor was 0.59 ± 0.07% due to the manure applied in fallow winter season. The N 2 O emission from FKSSL was 0.85 ± 0.79% of input N, and 3.4 times higher than PIAF. Slurry application contributed N 2 O emission 0.71 ± 0.37% of input N with 2 times higher than that of dry compost manure plots.

“…In the case of the genera Methylocapsa and Methylacystis, which prefer CH 4 , pMMO and sMMO are present and not repressed in the presence of other C compounds (Dedysh and Dunfield 2011). Finally, we cannot exclude that the apparent low CH 4 uptake rate observed in the N1C1 treatment is partly caused by enhanced CH 4 production because the addition of suitable C substrates may increase methanogenesis under anaerobic conditions (Topp and Pattey 1997;Dalal et al 2007, Win et al 2010, Sasada et al 2011. In fact, the soil moisture conditions in our experiment (40-80 % WFPS) do not exclude the possibility that methanogenesis took place in anaerobic microsites of the not water-saturated soil (Kotiaho et al 2010).…”

The inhibiting effect of nitrate fertilisation on methane uptake of a temperate forest soil is influenced by labile carbon

Upland soils are the most important terrestrial sink for the greenhouse gas CH 4 . The oxidation of CH 4 is highly influenced by reactive N which is increasingly added to many ecosystems by atmospheric deposition and thereby also alters the labile C pool in the soils. The interacting effects of soil N availability and the labile C pool on CH 4 oxidation are not well understood. We conducted a laboratory experiment with soil columns consisting of homogenised topsoil material from a temperate broad-leaved forest to study the net CH 4 flux under the combined or isolated addition of NO 3 − and glucose as a labile C source. Addition of NO 3 − and glucose reduced the net CH 4 uptake of the soil by 86% and 83%, respectively. The combined addition of both agents led to a nearly complete inhibition of CH 4 uptake (reduction by 99.4%). Our study demonstrates a close link between the availability of C and N and the rate of CH 4 oxidation in temperate forest soils. Continued deposition of NO 3 − has the potential to reduce the sink strength of temperate forest soils for CH 4 .

“…Application of nitrogen-rich organic amendments may supply available carbon and hence enhances the risk of global warming (Win et al 2010;Qin et al 2010). Therefore, it was necessary to study the effect of combined application of cover crop and silicate fertilizer on rice yield and methane emission.…”

Different response of silicate fertilizer having electron acceptors on methane emission in rice paddy soil under green manuring

et al. 2011

Cultivation of green manure plants during the fallow season in rice paddy soil has been strongly recommended to improve soil properties. However, green manuring may impact greenhouse gas emission, methane (hereafter, CH 4 ) in particular, under the flooded rice cultivation and thus, application of chemical amendments being electron acceptors can be an effective mitigation strategy to reduce CH 4 emissions in irrigated rice (Oryza sativa L.) field amended with green manure. To investigate the effect of iron (Fe) slag silicate fertilizer (hereafter, silicate fertilizer), which was effective in reducing CH 4 emission and increasing rice productivity, in green manureamended paddy soil, the aboveground biomass of Chinese milk vetch (hereafter, vetch) was added at rates of 0, 10, 20, and 40 Mg (fresh weight) ha −1 before the application of silicate fertilizer, which was added at rates of 0 and 2.3 Mg ha −1 . Silicate fertilization reduced the seasonal CH 4 flux by ca. 14.5% and increased rice yield by ca. 15.7% in the control (no vetch application) treatment.However, CH 4 production was increased by silicate fertilization in vetch-treated soil particularly at the initial rice growing stage, which was probably due to the enhanced decomposition of added organic matters by the silicate liming effect. In conclusion, silicate fertilization is not effective in reducing CH 4 production in green manureamended rice paddy soils and its use should be properly controlled.
