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

Phylogenetic and functional diversity of denitrifying bacteria isolated from various rice paddy and rice-soybean rotation fields.
TL;DR: It is shown that soil and other environmental factors, excluding cropping systems, could select for N(2)-producing denitrifiers and that crop rotation had minimal impact on the functional diversity of theDenitrifying strains.

TL;DR: In this article, the nature of the Fe species was probed with UV-vis, Mossbauer and EPR spectroscopies and H2-TPR results, which collectively indicate that primarily isolated and dinuclear Fe sites are present in Fe/SSZ-13, whereas Fe/Beta contains higher concentrations of oligomeric FexOy species.

Lowering N2O emissions from soils using eucalypt biochar: The importance of redox reactions
P Quin,Stephen Joseph,Stephen Joseph,Stephen Joseph,Olivier Husson,Scott W. Donne,David R. G. Mitchell,Paul Munroe,D Phelan,Annette Cowie,L Van Zwieten,L Van Zwieten +11 more
TL;DR: Evidence suggests that biochar has taken part in redox reactions reducing N2O to dinitrogen (N2), in addition to adsorption of N2S, at the lower water contents with increasing rates of biochar application.

TL;DR: In this article, the effect of increasing rates of inorganic N fertiliser provided as ammonium nitrate (AN) or calcium ammonium Nitrate (CAN) was evaluated.

Soil environmental factors rather than denitrification gene abundance control N2O fluxes in a wet sclerophyll forest with different burning frequency
TL;DR: In this paper, a 35-year-old repeated prescribed burning trial, with three treatments (no burning, 2 yearly burning and 4 yearly burning), was used to explore how the long-term repeated prescribed Burning affects N2O flux, key soil properties (inorganic N, dissolved organic carbon (DOC) and N, pH, electrical conductivity (EC), moisture), denitrification gene abundance and their interactions.
