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 potential of biochar to reduce N2O and CH4 emissions from agricultural practices including potential mechanisms behind observed effects was reviewed. But, the authors concluded that the largest future research needs lay in conducting life-cycle GHG assessments when using biochar as an on-farm management tool for nutrient-rich biomass waste streams.

Effect of Soil pH Increase by Biochar on NO, N2O and N2 Production during Denitrification in Acid Soils
TL;DR: This study indicates that stimulation of denitrification was mainly due to increases in labile carbon whereas change in product stoichiometry was mainlyDue to a change in soil pH.

Nitrous oxide from streams and rivers: A review of primary biogeochemical pathways and environmental variables
TL;DR: In this article, the authors studied the four main pathways leading to N2O production in soils and sediments, and found that incomplete denitrification is likely the globally dominant N 2O generating pathway and is favored by elevated nitrate concentrations, suboxic conditions, and sufficient organic carbon to promote reduction.
