L’article présente une estimation du renouvellement à moyen terme (dizaines d’années) du carbone profond des sols cultivés. Objectifs. Le stockage de carbone sous forme organique dans les sols est un moyen de limiter l’augmentation du CO2 global et le réchauffement climatique. L’objectif est de proposer une première quantification du renouvellement des horizons profonds (> 30 cm) qui contiennent environ la moitié du carbone organique des sols. Méthode. Nous avons effectué une synthèse d’études de la dynamique du carbone de 41 profils où le renouvellement du carbone est quantifié grâce au traçage isotopique par les abondances naturelles en carbone-13. Résultats. Le renouvellement du carbone profond est en moyenne quatre fois plus lent qu’e...
