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

TL;DR: In this paper, the authors examine long-term trends in reactive nitrogen (N) creation and efficiencies of Nr use within the continental US and estimate that human actions in the US have increased Nr inputs by at least 5 times compared to pre-industrial conditions.

Biochar does not affect soil N-transformations or microbial community structure under ruminant urine patches but does alter relative proportions of nitrogen cycling bacteria
TL;DR: In this paper, the authors investigated seasonal bacterial community change over two years in combination with a short-term winter study of N-transformations under bovine urine patches in a silt-loam pastoral soil in Canterbury, New Zealand.

TL;DR: Combined effects of antibiotics on denitrification may lead to nitrate retention and N2O release in estuarine and coastal ecosystems, and consequently cause cascading environmental problems, such as greenhouse effects and hyper-eutrophication.
