Aims: In the present work, carbon sequestration in different organs of 3 dominant of (A. , H. , and S. ) soil carbon sequestration of the corresponding habitats were examined.
Materials and Methods: The aboveground and belowground organs of 3 species were randomly sampled and oven dried. Three soil samples were taken from 0-0.15 and 0.15-0.3 m soil depths (SD). From these, soil organic carbon (SOC), soil texture (sand, silt, and clay), bulk density (BD), moisture content (MC), electrical conductivity (EC), and soil acidity (pH) were measured.
Findings: All of the tested had more carbon sequestration in the aboveground rather than organs. The highest value of carbon sequestration was observed in S. , which was about 18% and 90% more than the reported values of H. A. , respectively. Soil with S. greater content of organic carbon (1.5%) compared with H. 0.64%) and A. 0.63%), respectively. The results confirmed that soil top layer (0-0.15m) of patch area had more capability to sequester carbon (1.81%) in S. with the other species.
Conclusion: All the tested plants had higher carbon sequestration in the aboveground organs compared with the parts. The leaves had presented the lowest value compared with shoots and roots. The soil organic carbon of the species habitat varied from 0.63 (A. ) 1.5% (H. ). Moreover, with increasing the soil depth, carbon sequestration of the underlying soil layers decreased.
