  abstract = {{T}o respect the {P}aris agreement targeting a limitation of global warming below 2 degrees {C} by 2100, and possibly below 1.5 degrees {C}, drastic reductions of greenhouse gas emissions are mandatory but not sufficient. {L}arge-scale deployment of other climate mitigation strategies is also necessary. {A}mong these, increasing soil organic carbon ({SOC}) stocks is an important lever because carbon in soils can be stored for long periods and land management options to achieve this already exist and have been widely tested. {H}owever, agricultural soils are also an important source of nitrous oxide ({N}2{O}), a powerful greenhouse gas, and increasing {SOC} may influence {N}2{O} emissions, likely causing an increase in many cases, thus tending to offset the climate change benefit from increased {SOC} storage. {H}ere we review the main agricultural management options for increasing {SOC} stocks. {W}e evaluate the amount of {SOC} that can be stored as well as resulting changes in {N}2{O} emissions to better estimate the climate benefits of these management options. {B}ased on quantitative data obtained from published meta-analyses and from our current level of understanding, we conclude that the climate mitigation induced by increased {SOC} storage is generally overestimated if associated {N}2{O} emissions are not considered but, with the exception of reduced tillage, is never fully offset. {S}ome options (e.g. biochar or non-pyrogenic {C} amendment application) may even decrease {N}2{O} emissions.},
