“…In pure culture studies with nitrifying bacteria, N 2 O production at low O 2 levels has been shown to be correlated with an increase in NO 2 − (44) suggesting that the accumulation of NO 2 − in our soils, as in the pure cultures, promoted ND. Other workers have shown nitrite to promote N 2 O and NO production via abiotic reactions, such as with metals and with organic matter, especially in acidic soils (5,20,34). The N 2 O derived from these processes, termed chemodenitrification, would have the same isotopic signature as that generated by ND because NO 2 − is the source of N 2 O in both processes.…”

The continuous increase of nitrous oxide (N 2 O) abundance in the atmosphere is a global concern. Multiple pathways of N 2 O production occur in soil, but their significance and dependence on oxygen (O 2 ) availability and nitrogen (N) fertilizer source are poorly understood. We examined N 2 O and nitric oxide (NO) production under 21%, 3%, 1%, 0.5%, and 0% (vol/vol) O 2 concentrations following urea or ammonium sulfate [(NH 4 ) 2 SO 4 ] additions in loam, clay loam, and sandy loam soils that also contained ample nitrate. The contribution of the ammonia (NH 3 ) oxidation pathways (nitrifier nitrification, nitrifier denitrification, and nitrification-coupled denitrification) and heterotrophic denitrification (HD) to N 2 O production was determined in 36-h incubations in microcosms by 15 N-18 O isotope and NH 3 oxidation inhibition (by 0.01% acetylene) methods. Nitrous oxide and NO production via NH 3 oxidation pathways increased as O 2 concentrations decreased from 21% to 0.5%. At low (0.5% and 3%) O 2 concentrations, nitrifier denitrification contributed between 34% and 66%, and HD between 34% and 50% of total N 2 O production. Heterotrophic denitrification was responsible for all N 2 O production at 0% O 2 . Nitrifier denitrification was the main source of N 2 O production from ammonical fertilizer under low O 2 concentrations with urea producing more N 2 O than (NH 4 ) 2 SO 4 additions. These findings challenge established thought attributing N 2 O emissions from soils with high water content to HD due to presumably low O 2 availability. Our results imply that management practices that increase soil aeration, e.g., reducing compaction and enhancing soil structure, together with careful selection of fertilizer sources and/or nitrification inhibitors, could decrease N 2 O production in agricultural soils.

“…Nitrous oxide and NO are produced through the microbial processes of denitrification and nitrification and through abiotic chemodenitrification reactions (5)(6)(7). Heterotrophic denitrification (HD) is performed by heterotrophic bacteria using nitrate (NO 3 − ) or nitrite (NO 2 − ) as alternate electron acceptors to oxygen (O 2 ).…”

“…Nitrous oxide (N 2 O) is among the most important greenhouse gases, contributing by 6% to global warming (Loubet et al 2011;Ranucci et al 2011), and directly affects the stratospheric ozone layer (Willianms et al 1992;Ravishankara et al 2009). Nitrous oxide emitted from soils leads to N loss from the ecosystem and is produced by nitrification and denitrification microbiological activities (Skiba et al 1993;Ambus et al 2006;Jiang-Gang et al 2007;Senbayram et al 2012) and chemodenitrification at low pH (< 5.5) (Van Cleemput, Samater 1996). The major N 2 O source is denitrification (Skiba et al 1997;Skiba, Smith 2000;Ruser et al 2001).…”

AbstractŠima T., Nozdrovický L., Krištof K., Krupička J., 2014. Impact of the size of nitrogen fertiliser application rate on N 2 O flux. Res. Agr. Eng., 60: 24-29.The application rate of a nitrogen fertiliser is one of the most important factors that affect the nitrous oxide (N 2 O) flux. Calk ammonium nitrate with 27% nitrogen content was spread by a fertiliser spreader VICON RS-L connected with a tractor Zetor 16145 and incorporated into the soil by a power harrow Pöttinger Lion 301 six hours after spreading. Monitoring points were selected based on the size of application rate 0, 100, 200 and 300 kg/ha and were measured 7, 14, 21 and 28 days after fertiliser application and incorporation into the soil. Nitrous oxide emissions were measured by a photoacoustic field gas monitor INNOVA 1412 with a multipoint sampler INNOVA 1309. Based on the data obtained, there were found statistically significant differences among time intervals and among the size of the application rate at a 95.0% confidence level. Results have shown impacts of the size of fertiliser application rate and time interval after fertilisation on nitrous oxide flux.

“…Those conclusions was later expanded and supported at different levels by Jiang-Gang et al (2007) and later on by Senbayram et al (2012). In addition it was concluded by Van Cleemput and Samater (1996) that the chemodenitrification at low level of pH (< 5.5) was considered as influencing factor as well.…”

Fertilizers are an important tool to maintain soil fertility and as an enhancement for the efficient crop production. The system of fertilizers application affects the final dose and commonly causes local overdosing or insuficient spatial distribution of fertilizers which are a very important source of nitrous oxide emissions (N 2 O) from the soil into the atmospher observation of such phenomenon are among the key factors defining environmental impacts of agriculture. A study was conducted to observe the effect of application dose of fertilizer on N 2 O emission from the soil. CAN (Calcium ammonium nitrate -consist of 27 % nitrogen) was spread by a fertiliser spreader Kuhn Axera 1102 H-EMC aggregated with a tractor John Deere 6150 M. Incorporation of fertilizer into the soil was done by power harrow Pöttinger Lion 302. The application dose was set at 0, 100, 200 and 300 kg. ha -1 while monitoring points were selected at the base of this application doses in respective places. Measurements were conducted at time intervals 7, 14, 21 and 28 days after fertiliser application and following incorporation. Nitrous oxide emissions were measured by field gas monitor set INNOVA consisting of a photoacoustic gas monitor INNOVA 1412 and a multipoint sampler INNOVA 1309. Statistically significant differences was found among time intervals and among the application dose (p > 0.05). It was observed that the application dose of selected fertilizers has the direct effect on nitrous oxide (N 2 O) emissions released from soil into the atmosphere. An increase of greenhouse gas emissions was observed in range from 0.83 to 152.33 %. It can be concluded that the local overdose of fertilizers negatively affects environmental impact of agricultural practices at greenhouse gas emissions (GHGs).
