Soil texture and precipitation influence soil organic carbon sequestration. This research measured soil texture to assess the organic carbon sequestration potential of the soils in agroforestry parklands according to a rainfall gradient for sites recommendations to promote agroforestry to mitigate climate change in Burkina Faso. Soil samples were collected at layers 0- 10, 10 - 20 and 20 - 30 cm in agroforestry parklands with Vitellaria paradoxa C. F Gaertn (Karite) and Parkia biglobosa (Jacq.) Benth (Nere) at Tougouri, Nobere and Sokouraba respectively located in the sahelian, sudano-sahelian savanna and sudano-guinean savanna zones. The clay, silt and sand content in soil was measured using the spectrophotometry infrared method. The soils at all the sites showed a balanced texture. Clay appears to be the textural component that would influence soil organic carbon sequestration and it was higher at Sokouraba (30,499 ± 0,456 %) and Tougouri (30,980 ± 0,451 %). It was also higher in layers 10_20 cm (27,861 ± 0,474 %) and 20_30 cm (31,759 ± 0,498 %) and the same trends were observed at Sokouraba and Tougouri. The precipitation that is a determining factor in soil organic carbon sequestration, Sokouraba could be recommended to promote agroforestry for climate change mitigation.
