Soil carbon is very important in food security, ecosystems, and environmental health, especially in the context of global climate change. This study was to determine the effect of carbon sequestration from bamboo biochar on increasing the productivity of marginal soils in the second planting season planted with soybean [ Glycine max L.]. This study used a completely randomized design with 3 replications in 5 treatments: A = 0.0% [0g pot −1 ] B = 0.5% [173g pot −1 ]; C = 1.0% [348g pot −1 ]; D = 1.5% [520g pot −1 ] and E = 2.0 [693g pot −1 ] of bamboo biochar. The results showed that carbon sequestration from bamboo biochar had a significant effect on the chemical properties of Ultisols, such as increasing pH, available P, organic C, total N, CEC, and Ca-exch and could reduce Al-exch, by 0.90 units, 2.50 ppm P, 1.12% C, 0.13% N, 5.48; 1.79 and 0.88 cmol c kg −1 , compared to controls and increase in soybean growth and NPK nutrient uptake in stems and leaves [3.57g N, 2.61g P, 4.64g K], also in roots [0.93g N, 1.03g P, 0.94g K], compared to controls. Carbon sequestration from bamboo biochar with 2% application can increase the productivity of marginal soil [Ultisols] and soybean [ Glycine max L.].
