  abstract = {{A}groforestry systems ({AFS}) are recognized as one of the practices with high potential to store carbon in soils. {I}n the {I}tasy region, {AFS} were introduced to improve farmers' livelihoods by diversifying income sources and to address problems related to soil degradation. {P}revious studies in the region have shown the potential of {AFS} to store organic carbon in the soil. {I}n the present work, we carried out further studies to assess the main factors affecting {SOC} stocks in {AFS}. {I}n 2014, we performed a soil sampling on 137 {AFS} farmers'plots to assess {SOC} stocks in different {AFS}. {I}n 2018, a second sampling was carried out to calculate {SOC} storage rates using the diachronic approach on 30 most representative {AFS}. {T}he results revealed that the factors "age of the system" and "type of organic inputs" significantly affected {SOC} stocks in {AFS}. {SOC} stocks increased significantly over time in {AFS} plots, benefiting from regular organic inputs such as manure and/or compost. {I}n contrast, {SOC} stocks remained unchanged over time in {AFS} plots where no organic fertilization was used. {O}ur study showed a substantial {SOC} storage up to 47 parts per thousand year(-1), mainly explained by regular additions of organic inputs to maintain soil fertility and crop production. {H}owever, to fully understand the process of {SOC} storage in this context, further works, such as the analysis of the link between organic matter quality and the {SOC} storage process, and the quantification of the share of soil carbon inputs derived from tree biomass should be undertaken.},
