Résumé : The unique long-term experiment of Sana offers the possibility to analyze soil carbon dynamics over more than 40 years under different agricultural practices in the Sudano-Sahelian region. Complete historical datasets offer the possibility to test carbon models. Maintaining a high carbon level here appeared more difficult than predicted by current carbon models. This finding suggests additional processes to be included in carbon models.
