Outline of Final Research Achievements

Impact of the development of tropical peat swamp forest into oil palm plantation (OPP) was investigated in terms of decomposition rates and processes of tropical peat under OPP management, and the factors affecting to it. Our results showed: 1) grain size of peat becomes smaller as the decomposition proceeds, which, depending on peat type, suppresses decomposition by negative feedback. 2) Water content influences bidirectionary on peat decomposition: as the water content increases, oxygen diffusion rate lowers on one hand, but mobility of substrates and enzymes increases on the other hand. 3) Compaction of peat suppresses oxygen diffusion rate, resulting in the suppression of peat decomposition. 4) Microbial community structure of tropical peat under primary forest is similar, while some proportional variation exists, among different forest types. 5) Precipitation amount during wet-season may influence decomposition of peat in OPP during ensuing dry season.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は,地球規模の炭素バランスに大きく影響を及ぼす熱帯泥炭土の,開発に伴う炭素循環プロセスの変化とそのメカニズム,および,熱帯泥炭土の持続的農業利用を成功させるための圃場管理に関する貴重な基礎的知見となるものである。熱帯泥炭は油ヤシプランテーション開発に伴い急速に分解すると一般に考えられてきたが,適切な泥炭のタイプを,適切な管理下において利用することにより,分解速度を低く保つことができる可能性を示した意義は大きいと考えられる。
