“…These results agree with those reported by Bathia et al (2005), who verified that substitution of mineral fertilizer by organic fertilizer increased methane emissions by 60 % and GWP by 28 % in a rice-maize rotation.…”

“…In a long term study (9 years) of GWP in conventional agricultural systems, Robertson et al (2000) verified far lower GWP values than Bathia et al (2005) with 161 g day -1 CO 2 -equivalent m -2 . These results reinforces the potential of use of these organic residues to increase GHG emissions, mainly those rich in N.…”

“…This index is useful in comparisons of relative efficiency of each GHG in trapping heat, using a standard gas as reference, which, to simplify matters, was CO 2 . For the calculation, it was assumed that in a 100 year period GWP is 21 for CH 4 , 310 for N 2 O and 1 for CO 2 (Bathia et al, 2005). GWP of the different treatments was calculated as in equation 1 (Robertson, et al, 2000;Bathia et al, 2005 …”

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.

A field experiment was conducted in Bangladesh Agricultural University Farm to investigate the mitigating effects of soil amendments such as calcium carbide, calcium silicate, phosphogypsum, and biochar with urea fertilizer on global warming potentials (GWPs) of methane (CH 4 ) and nitrous oxide (N 2 O) gases during rice cultivation under continuous and intermittent irrigations. Among the amendments phosphogypsum and silicate fertilizer, being potential source of electron acceptors, decreased maximum level of seasonal CH 4 flux by 25-27 % and 32-38 % in continuous and intermittent irrigations, respectively. Biochar and calcium carbide amendments, acting as nitrification inhibitors, decreased N 2 O emissions by 36-40 % and 26-30 % under continuous and intermittent irrigations, respectively. The total GWP of CH 4 and N 2 O gases were decreased by 7-27 % and 6-34 % with calcium carbide, phosphogypsum, and silicate fertilizer amendments under continuous and intermittent irrigations, respectively. However, biochar amendments increased overall GWP of CH 4 and N 2 O gases.

“…However, increased use of nitrogenous fertilizer and irrigation would increase the emission of greenhouse gases such as CO 2 , CH 4 and N 2 O causing global warming and climate change (IPCC, 2007;Pathak and Wassmann, 2007). Thus it is important to quantify the trade-offs between rice production and GWP, which is defined as the ratio of the warming of atmosphere caused by one substance to that caused by a similar mass of CO 2 (Bhatia et al, 2005). This study was undertaken to evaluate the effect of intermittent irrigation with different fertilization background on N 2 O emission and total GWP during rice cultivation in Korea.…”
