“…Chu et al (2007) reported values of 0.427-0.524 g CO 2 -C m -2 d -1 CO 2 efflux from an Andisol upland field in Japan under different types of fertilizer management using a closed chamber method that was the same as that used in the present study. Similarly, Nakadai et al (2002) conducted a field experiment using a chamber method and reported that the average soil CO 2 efflux from an Andisol under the tillage treatment was in the range of 0.73-1.39 g CO 2 -C m -2 d -1 according to the season.…”

Accurate measurements of CO2 efflux from soils are essential to understand dynamic changes in soil carbon storage. Column incubation experiments are commonly used to study soil water and solute transport; however, the use of column incubation experiments to study soil CO2 efflux has seldom been reported. In this study, a 150-day greenhouse experiment with two treatments (no-tillage and tillage soils) was conducted to evaluate the applicability of soil column incubation experiments to study CO2 efflux. Both the chamber measurement and the gradient method were used, and results from the two methods were consistent: tillage increased soil cumulative CO2 efflux during the incubation period. Compared with fieldwork, incubation experiments can create or precisely control experimental conditions and thus have advantages for investigating the influence of climate factors or human activities on CO2 efflux. They are superior to bottle incubation because soil column experiments maintain a soil structure that is almost the same as that in the field, and thus can facilitate analyses on CO2 behaviour in the soil profile and more accurate evaluations of CO2 efflux. Although some improvements are still required for column incubation experiments, wider application of this method to study soil CO2 behaviour is expected.

“…This was the first report of new land use pattern by co-cropping herbal plant to mitigate N 2 O emitted from agricultural soil. Compared to some other agricultural practices such as N fertilizer management (KAISER et al, 1998;Ulrike et al, 2003;Chu et al, 2007;Fub et al, 2011;Aguilera et al, 2013;Fisk et al, 2015;Frederico et al, 2015), reduced tillage (Fub et al, 2011;Fisk et al, 2015;Frederico et al, 2015), drip irrigation and fertigation (Aguilera et al, 2013;Kennedy et al, 2013), organic amendments (Qiu et al, 2013;Aguilera et al, 2013;Fisk et al, 2015), crops straw incorporation (Ma et al, 2009;Yang et al, 2015), biochar (Xiang et al, 2015), nitrification inhibitor (Ranucci et al, 2011;Barneze et al, 2015), this newly developed approach could be more effective and economical as it was simple and easily to conduct in a low-cost manner for farmer. Of course, it needs to be further improved and optimized.…”

Greenhouse gas (GHG) emitted from agricultural field was received considerable attention worldwide, depending on differed land use and cropping system. An innovative strategy to mitigate agricultural N 2 O by intercropping traditional Chinese medicinal herb Isatis indigotica in winter wheat field was assessed. By exogenously applying root exudates of I. indigotica in a lab incubation study, we testify and quantify whether N 2 O emission was inhibited.Results demonstrated great reduction of N 2 O emission from winter field soil intercropping I. indigotica (NPKWR-N+P+K+wheat+I. indigotica) compared to CK (NPKW-N+P+K+wheat but no I. Indigotica) was found. N 2 O emission in treatment of NPKWR was decreased by 32% than that in CK during the whole winter wheat growth season, among which the best decreasing N 2 O emission was obtained in the stage of grain filling of winter wheat, N 2 O emitting from NPKWR was reduced by 60% than that in CK. The N 2 O emission intensity per kg of harvested wheat grain treated with I. indigotica was declined to 0.15 g N 2 O/kg grain from 0.24 g N 2 O/kg grain in CK.qPCR (quantitative fluorescent polymerase chain reaction) analysis indicated nitrifying microbial population in wheat soil was severely suppressed by I. indigotica. The number of qPCR gene copy in both soil intercropping I. indigotica and exogenously applying root exudates of I. indigotica was lower than in CK. Such trend of decreased microbial population number was in agreement with that of N 2 O emission from winter wheat field. This suggested that intercropping I. indigotica was a practical and simple technique to reduce N 2 O emission from winter wheat field which was an effective strategy for mitigating and adapting global change worldwide in agriculture.

“…Soils fertilized with N are sources with significant contribution to the total N 2 O emission (Harrison & Webb, 2001). Even methane and CO 2 emissions could be increased with N application as fertilizer (Chu et al, 2007), offering better conditions for the soil microbiota development as well as diminishing the C/N ratio of the medium and increasing oxygen consumption, leading to the formation of anaerobic microsites in the soil.…”

Organic residue application into soil alter the emission of gases to atmosphere and CO 2 , CH 4 , N 2 O may contribute to increase the greenhouse effect. This experiment was carried out in a restoration area on a dystrophic Ultisol (PVAd) to quantify greenhouse gas (GHG) emissions from soil under castor bean cultivation, treated with sewage sludge (SS) or mineral fertilizer. The following treatments were tested: control without N; FertMin = mineral fertilizer; SS5 = 5 t ha -1 SS (37.5 kg ha -1 N); SS10 = 10 t ha -1 SS (75 kg ha -1 N); and SS20 = 20 t ha -1 SS (150 kg ha -1 N). The amount of sludge was based on the recommended rate of N for castor bean (75 kg ha -1 ), the N level of SS and the mineralization fraction of N from SS. Soil gas emission was measured for 21 days. Sewage sludge and mineral fertilizers altered the CO 2 , CH 4 and N 2 O fluxes. Soil moisture had no effect on GHG emissions and the gas fluxes was statistically equivalent after the application of FertMin and of 5 t ha -1 SS. The application of the entire crop N requirement in the form of SS practically doubled the Global Warming Potential (GWP) and the C equivalent emissions in comparison with FertMin treatments.
