We measured the flux of nitrous oxide (N₂O) in three different land uses (primary forest, oil palm plantation, and rubber plantation) in Peninsular Malaysia. The N₂O emission rate in the primary forest was higher than those in the plantations throughout the experimental period. This result suggests that primary forest soil is a greater source of N₂O than that of oil palm and rubber plantations. The rate of N₂O emission in the primary forest showed a clear variation during the experimental period, with higher values from wet soils and lower values from dry soils, whereas N₂O emission rates in the plantations showed little variation. The proportions of soil surface carbon and nitrogen in primary forest were three times those in the plantations. The difference in soil carbon and nitrogen contents between the primary forest and plantations may have affected the rates of N₂O emission from the soils.
