TLDR
In this paper, the ozone depletion potential-weighted anthropogenic emissions of N2O with those of other ozone-depleting substances were compared, and it was shown that N 2O emission currently is the single most important ozone-destroying emission and is expected to remain the largest throughout the 21st century.Abstract:
By comparing the ozone depletion potential-weighted anthropogenic emissions of N2O with those of other ozone-depleting substances, we show that N2O emission currently is the single most important ozone-depleting emission and is expected to remain the largest throughout the 21st century. N2O is unregulated by the Montreal Protocol. Limiting future N2O emissions would enhance the recovery of the ozone layer from its depleted state and would also reduce the anthropogenic forcing of the climate system, representing a win-win for both ozone and climate.read more

Effect of nitrogen and waterlogging on denitrifier gene abundance, community structure and activity in the rhizosphere of wheat.

TL;DR: Both anoxia and N limitation significantly influenced the structure and function of denitrifier communities in the rhizosphere, with reduced root-derived carbon postulated to play an important role.

Actinobacterial nitrate reducers and Proteobacterial denitrifiers are abundant in N2O metabolizing palsa peat
Katharina Palmer,Marcus A. Horn +1 more
TL;DR: The collective data suggest that (i) the source and sink functions of palsa peat soils for N2O are associated with denitrification, (ii) actinobacterial nitrate reducers and nirS-type and nosZ-harboring proteobacterial denitrifiers are important players, and (iii) acidic soils like p salsa peats represent reservoirs of diverse acid-tolerant denitRifiers associated with N2 O fluxes.

Compact and portable open-path sensor for simultaneous measurements of atmospheric N2O and CO using a quantum cascade laser.
TL;DR: A compact and portable open-path sensor for simultaneous detection of atmospheric N(2)O and CO has been developed with a 4.5 μm quantum cascade laser and an in-line acetylene gas reference cell allowing for continuous monitoring of the sensor drift and calibration in rapidly changing field environments.

Micrometeorological measurements over 3 years reveal differences in N2 O emissions between annual and perennial crops.

TL;DR: It is found that a specific manure management practice can lead to increases or reductions in annual N2 O emissions depending on environmental variables, and general manure management recommendations should be avoided because interannual weather variability has the potential to determine if a specific practice is beneficial or detrimental.
