| Outline of Final Research Achievements |
We unveiled the accumulation rate, physicochemical properties, and decomposition rate of tropical peats formed under three major types of forest (Alan Bunga, Alan Batu, and Mixed peat swamp) in Sarawak, Malaysia. Accumulation of tropical peat began about 4,000 years ago, and the accumulation rate ranged from 0.07 to 0.20 cm/year. When incubate virgin peat under oil palm plantation (OPP) environment, all types of peat showed rapid decomposition. Alan Bunga peat, which contains larger percentages of polysaccharides, decomposed two times faster than mixed peat swamp peat. Particle size of peat lowered soon after incubation for all types of peat.
