The influences of chemical fertilizers and a nitrification inhibitor on greenhouse gas fluxes (N_2O and CH_4) 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 applications of urea, a single application of controlled-release fertilizer (CRF-LP30) or urea+dicyandiamide (DCD; a nitrification inhibitor), and no nitrogen application (control). Cumulative amounts of N_2O emitted from the field were 1.87, 1.70, 1.06, and 0.42 kg N_2O-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 N_2O by 55.8% compared with urea. On the other hand, the soil acted as a sink for CH_4 in the CRL-LP30, control, and urea+DCD plots with value of-0.09, -0.06 and -0.06 kg CH_4-C ha^<-1> season<-1>, respectively. When the viability of AOB (ammonia-oxidizing bacteria) and NOB (nitriteoxidizing bacteria) were monitored, AOB numbers were correlated with the N_2O emission. These results suggest that 1) there is a potential for reducing emissions of N_2O by applying DCD, and 2) corn fields treated with CRF or urea+DCD can act as a sink for CH_4 in a tropical humid climate.
