Tillage practices and climate affect the release of HGs. No tillage (DMC) systems may increase CO2?C fixation in soil but also N2O and CH4 emissions. The aim of this article is to question whether the positive effect of a DMC system observed on carbon storage for the topsoil layer in Cerrado soils is offset or not by the N2O and/or CH4 emissions.  aBrazil  aCerrado  aPlantio Direto  aSolo  aCH4  aN2O  aPlantio convencional  aSoil C sequestration1 aOLIVER, R.1 aSCOPEL, E.1 aDOUZET, J.
