We quantified the C stocks in plant biomass, woody necromass, litter and soil (0-30 and 30-100 cm) for the five main land uses - forest, tree plantation, young and adult palm groves, croplands - of Ferralsols on the Allada plateau in southeast Benin. Forests have the highest total C stocks (389 +/- 54 Mg C ha(-1)) compared with other land uses (222 +/- 33, 154 +/- 6, 105 +/- 2, 77 +/- 3 Mg C ha(-1) in tree plantations, adult palm groves, young palm groves and croplands, respectively). The C stocks are higher in the biomass than in the soil (0-100 cm), e.g. in the forest, stocks were 279 +/- 54 Mg C ha(-1) in the biomass versus 83 +/- 2 Mg C ha(-1) in the soil. Differences of soil C stocks between land uses are low (approximate to 28 Mg C ha(-1)) and concentrated in topsoils. The structure and species diversity of the forest partly explained the variability and the high C biomass compared to tree plantations. Type of forest and plantations is important to consider in conserving C stocks in landscapes. specialized Organic stocks carbon pools climate change allometric models BENIN 068 021 020 13 1 249-265 2022 1758-3004 https://www.documentation.ird.fr/hor/fdi:010085157 10.1080/17583004.2022.2074314 1758-3004 [F B010085157] https://www.documentation.ird.fr/hor/fdi:010085157 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2022-07/010085157.pdf IRD - Base Horizon / Pleins textes 2022-07-01 2025-02-24 fdi:010085157 fre
