  abstract = {{A} significant fraction of soil organic carbon, named stable organic carbon ({C}) pool, has residence times longer than centuries and its vulnerability to land use or climatic changes is virtually unknown. {L}ong-term bare fallows offer a unique opportunity to isolate the stable organic pool of soils and study its properties. {W}e investigated the vulnerability of the stable organic {C} pool to fresh organic matter inputs by comparing the mineralization in a long-term bare fallow soil with that of an adjacent arable soil, containing stable {C} as well as more labile {C}. {F}or this, we amended or not the soil samples with two different {C}-13-labelled fresh organic matter (straw or cellulose). {I}n all cases we found a positive priming effect (i.e. an increased mineralization of soil organic carbon) when fresh organic matter was added. {B}y comparing the results obtained on both soils, we estimated that half of the "primed" {C} in the arable soil due to straw addition as fresh organic matter, originated from the stable {C} pool. {O}ur results suggest that under such conditions, which frequently occur, the stable pool of soil organic matter may largely contribute to soil extra-{CO}2 emissions clue to priming effect. {C}onsequently, the {C} storage potential of this pool may be modified by changes in land use and/or biomass production that might change the priming of the mineralization of the stable pool of soil organic carbon.},
