| Outline of Final Research Achievements |
Carbon (C) budget and dynamics of nitrogen (N) in sago palm gardens established on a tropical peat soil were investigated in Mukah, Sarawak, Malaysia. New fertilization techniques were also tested. The rate of supplying litter C from sago palm and the mineralization rate of sago litter C, the increasing rate of biomass C with sago growth, weed biomass C, and C emission from soil were monitored, and the size of sago palm and peat soil as C pools was estimated. Although the sum of C input was smaller than that of C output, it was suggested that the field cane act as C sink by regulating the period of transplantation. The proportion of fertilized N used by sago palm was small even in the initial growth stage, while a large amount of N fixation and soil N mineralization maintained the plant production. The application of slow release fertilizer to the nursery improved the sago growth after transplantation.
