The project was conducted to determine the carbon and nitrogen compound and to
identify the relationship of the nutrient content with the rate of decomposition in four
different species of swamp vegetation which are Alstoniaspatulata sp.,
Macarangahypoleuca sp., Elaeocarpusmasterii sp and Malaleuca Cajaputi. Leaf litters
of each species were buried at field for up to 6 months in the litter bags. Then, the
content of organic matter was determined by using CHNS analyzer for each species.
The results on patterns of changes in nutrient concentration in leaf litter were slightly
different between the species. Nitrogen content in Alstoniaspatulata sp.>
Elaeocarpusmasterii sp.>Macarangahypoleuca sp.> Malaleuca Cajaputi. While the
carbon content in are Alstoniaspatulata sp.> Malaleuca Cajaputi >
Elaeocarpusmasterii sp. > Macarangahypoleuca sp. This showed that the
Alstoniaspatulata sp. has the highest of nutrient concentration either carbon or
nitrogen. The higher of nutrient content in the leaf litter will give faster rate of
decomposition. Besides, the microbe activities also give effect to the rate of
decomposition of the litter. The ratio C:N of decomposing leaves have decreased for
every species except for Macarangahypoleuca sp.
