“…In fact, increases in tree biomass are the visible effect of fixing carbon in the ecosystem 10 . However, soil carbon dynamics should also be identified because changes in soil carbon stock, which is the biggest carbon pool in the terrestrial ecosystem, might significantly affect CO 2 concentration 9,11,13 .…”

Soil respiration is a crucial carbon flux for determining carbon balance in the forest ecosystem. In Kanchanaburi, western Thailand, we measured soil respiration at different stand ages (1, 6 and 21 year-old) of teak (Tectona grandis) plantations. There were no significant differences in soil respiration among plots of different ages. Soil respiration rates showed a clear seasonal pattern of a high rate in the rainy season from April to November and a low rate in the dry season from December to March. The contribution of organic layer, roots and soil to total soil respiration was 17, 15 and 68%, respectively, in the 6 year-old teak plantation (T-Y plot). Total soil respiration rate was significantly correlated with soil water content in the 0-30 cm layer. The annual amount of CO 2 efflux from the forest floor was estimated to be 1,062-1,154 gC m -2 y -1 in the teak plantations in 1997. In 1998, annual CO 2 efflux declined to 80% of that in 1997 in the T-Y plot, probably due to low rainfall.

“…Among the reference data, the site productivity of the teak in this watershed was the highest value. The increase rate of carbon stock of 9.3 MgC ha -1 y -1 was almost equivalent to 24 m 3 ha -1 y -1 for the stem volume increment, which would almost represent the upper limit of the mean annual increment of teak plantations under short rotation (< 20 years) system (Enters, 2000;Kiyono et al, 2007). This is probably due to the soil properties: well drained, rich in calcium, and high soil pH (Takahashi et al, 2009), namely ideal soil conditions for teak growth (Kaosa-ard, 1998;Tanaka et al, 1998 In the natural forest, the density of trees above 5 cm in DHB was almost stable with slight fluctuation during the 8 years of monitoring, ranging from 174 to 199 trees ha -1 and 16.9 to 17.7 m 2 ha -1 for basal areas (Fig.…”
