Inefficient used of urea fertilizer contributes to producing methane (CH 4 ) and nitrous oxide (N 2 O) emissions. One of the options to mitigate CH 4 and N 2 O emissions is through the use of nitrification inhibitors (NI). The objective of this study was to evaluate the effectiveness of some plant-based NI (NNI) on CH 4 and N 2 O production under two different soils types. An incubation experiment was arranged using 2 x 3 x 3 factorial designs. All treatments were conducted with three replicates. The first factors were paddy soils (Inceptisols and Vertisols), the second were NNI (coconut husk, coffee waste, and Ageratum conizoides) and the third were the rate of the NNI (10, 20 and 30 ppm). The results showed that CH 4 production was found lowest at the rate of 30 ppm of coconut husk application. Coconut husk at the rate of 20 ppm produced the lowest N 2 O production. Based on the global warming potential (GWP), the lowest production was the application of Ageratum conizoides at the rate of 30 ppm. Applying a higher rate of natural NI resulted in lower productions of CH 4 and N 2 O. Chemical contents of natural NI influenced microbial activities that produce CH 4 and N 2 O through nitrification and denitrification processes.
