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

Effects of silver nanoparticles on nitrification and associated nitrous oxide production in aquatic environments
Yanling Zheng,Lijun Hou,Min Liu,Silvia E. Newell,Guoyu Yin,Chendi Yu,Hongli Zhang,Xiaofei Li,Dengzhou Gao,Juan Gao,Rong Wang,Cheng Liu +11 more
TL;DR: The release of AgNPs into the environment should be controlled because they interfere with nitrifying communities and stimulate N2O emission and this study highlights the molecular underpinnings of the effects ofAgNPs on nitrification activity.

nirK-harboring denitrifiers are more responsive to denitrification-inducing conditions in rice paddy soil than nirS-Harboring bacteria
TL;DR: Clones related to the NirS of Burkholderiales and Rhodocyclales, and NirK distantly related to known denitrifiers increased their proportion in response to the denitrification-inducing conditions, and therefore, might be involved in Denitrification in rice paddy soil.

Mitigating Nitrous Oxide Emissions from Corn Cropping Systems in the Midwestern U.S.: Potential and Data Gaps
TL;DR: More data collection on side-by-side comparisons of common and alternative management practices, especially those pertaining to N-placement, N-timing, and N-source, in combination with biogeochemical model simulations, will be needed to further develop and improve N2O mitigation strategies for corn cropping systems in the major corn producing regions in the U.S. and Canada.

N2O emission from cropland field soil through fungal denitrification after surface applications of organic fertilizer
Wei Wei,Kazuo Isobe,Yutaka Shiratori,Tomoyasu Nishizawa,Nobuhito Ohte,Shigeto Otsuka,Keishi Senoo +6 more
TL;DR: In this paper, the authors focused on the large N2O emission from cropland soil that occurs after granular organic fertilizers were applied to the surface, and they determined the population density and community composition of fungi in the surface-fertilized and non-Fusarium soils in the field using colony counting, denaturing gradient gel electrophoresis and subsequent phylogenetic analyses.
