. CO2 emission consists of autotrophic and heterotrophic respirations. An autotrophic emission is not considered as negative, and in contrast, a heterotrophic oxidation of peat soils has detrimental impact on the global warming. The aim of this study is to investigate rates of emissions between autotrophic and heterotrophic respirations, generated by oil palm (Elaeis guineensis) plantation on shallow peat. The research site was located in Rasau Jaya Umum, Kubu Raya District, West Kalimantan Province, Indonesia. The ages of palms are 6 to 7 years. A total of twelve closed chambers were placed in both rhizospheres, representing autotrophic and heterotrophic oxidation, and non-rhizospheres, repsenting heterotrophic oxidation only. CO2 emissions were measured once a month, with an infrared gas analyzer (EGM-4), from January to May 2015. The results show rhizospheric emissions are significantly higher than non-rhizospheric emissions, i.e., 0.93 and 0.44 g m-2 hr-1, respectively. Values of CO2 emissions increase as water table level is low, indicating a positive correlation between water table level and CO2 emission from peats.
