Abstract
Tropical rainforests cover about 19.37 million ha 60 of Malaysia;s total area and about 8.71 million ha are found in Sarawak Malaysia. Logging mining and shifting cultivation contribute to deforestation in Sarawak. The objective of this study was to compare humic acids HA and stable carbon carbon in HA storage of rehabilitated and secondary forests soils. Except for 20-40 cm of the secondary forest soil where the quantity of total C stored was significantly lower than that of the rehabilitated forest soil C storage was similar irrespective of forest type and depth. Nevertheless stable C sequestered in HA was generally higher in the rehabilitated forest soil than in the secondary forest soil. This was attributed to higher yield of HA in the rehabilitated forest soil partly due to better humification at 20-40 cm in the rehabilitated forest soil. The findings suggest that organic C in HA realistically reflects C storage in the soils of the two forests.
