Abstract

The release of nitrous oxide (N2O) from agricultural activities contributes to the increase of greenhouse gases in the atmosphere. In this study, the amount of nitrogen fertiliser used in an oil palm plantation of different stages (immature and mature) was estimated. Data of fertilising scheme at the oil palm plantation for oil palms varying in age (planted between 1986 and 2009) was used. Estimation of nitrous oxide emissions and the resulting CO2-equivalent (CO2-eq) emissions were calculated for each category of the oil palm. The amounts of N-fertiliser applied were between 102137 kg N/ha. The resulting N2O emissions were between 19.07-22.10 kg N2O-N/ha, which corresponds to CO2-eq of between 2223.53-2700.42 kg CO2-eq/ha. It was also estimated that about 29.87-34.63 g CO2 were emitted per MJ crop. The N2O emission per ha oil palm was found to decrease from immature stage until maturely-developed stage spanning 20 years. The CO2-eq amount decreased only after ten years of oil palm development. The results were also compared for synthetic nitrogen fertiliser-induced emissions within tropical regions.
