The influences of chemical fertilizer and a nitrification inhibitot on greenhouse gas fluxes (N2O) in a corn field in Indonesia were investigated using a closed chamber. Plots received 45+45 kg-N ha-1 of nitrogen fertilizer by split application of urea, a single application of controlled-release fertilizer (CRF-LP30) or urea+dyciandiamide (DCL, a nitrification inhibitor), and no nitrogen application (control). Cumulative amounts of N2O emitted from the field were 1.87, 1.70, 1.06, and 0.42 kg N2O-N ha-1 season-1 for the urea, CRF-LP30, urea+DCD, and control plots, respectively. The application of urea+DCD reduced the emission of N2O by 55.8% compared with urea. On the other hand, the soil acted as a sink for CH4 in the CRL-LP30, control, and urea+DCD plots with value of -0.09, -0.-6 and -0.06 kg CH4-C ha-1 season-1, respectively. When the viability of AOB (ammonia-oxidizing bacteria) and NOB (nitrite-oxidazing bacteria) was monitored. AOB numbers were corrected with the N2O emission. These results suggested that 1) there is a potential for reducing emission of N2O by applying DCD, and 2) corn fields treated with CRF or urea+DCD can act as a sink for CH4 in tropical humid climate Key words: Indonesia upland soil, nitrification inhibitor, nitrifier population
