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

Global metaanalysis of the nonlinear response of soil nitrous oxide (N2O) emissions to fertilizer nitrogen
TL;DR: A first quantitative comparison of N2O emissions for all available studies that have used multiple N rates shows that a nonlinear emission factor better represents global emission patterns with lower uncertainty, offering more power for balancing the global N2 O budget and for designing effective mitigation strategies.

Biochar's role in mitigating soil nitrous oxide emissions: A review and meta-analysis
Maria Luz Cayuela,L. Van Zwieten,Bhupinder Pal Singh,Simon Jeffery,Asunción Roig,Miguel A. Sánchez-Monedero +5 more
TL;DR: In this paper, a meta-analysis using published literature from 2007 to 2013 showed that biochar reduced soil N2O emissions by 54% in laboratory and field studies and that the biochar feedstock, pyrolysis conditions and C/N ratio were key factors influencing emissions.
Journal ArticleDOI
Agricultural benefits and environmental risks of soil fertilization with anaerobic digestates: a review.
TL;DR: In this paper, a review of the legislative, chemical, agronomic and environmental literature on anaerobic digestates is presented, showing that digestates can be considered as organic amendments or organic fertilizers, when properly handled and managed.
