Stem biomass (kg)	97.0 (52.2%)	116.56 (61.3%)
Above-ground biomass (kg)	157.9 (82.2%)	163.28 (88.53%)
Root biomass (kg) (below-ground biomass)	33.4 (17.8%)	21.63 (11.5%)
Total biomass of the sampled tree (kg)	191.3	184.98

Figure 3. Organic carbon content of the soil with different soil layers from the X. xylocarpa (A) and P. macrocarpus (B) plantations. The different letters indicate significant differences in SOC among the soil depths according to DMRTs at a 5% level of probability. The letters are the rank order from highest to lowest value (alphabetically). Open bar indicates the standard error.

Figure 4. Soil bulk density at the two plantations. Different letters indicate significant differences in soil bulk density among the study sites according to Duncan's multiple range tests at a 5% level of probability. The letters are the rank order from highest to lowest value (alphabetically). Open bar indicates the standard error.
