Ammonia loss from urea significantly hinders efficient use of urea in agriculture. The level of nitrous oxide (N₂O) a long-lived greenhouse gas in atmosphere has increased mainly due to anthropogenic source, especially application of nitrogen fertilizers. There are reports in the literature showing that the addition of zeolite to N sources can improve the nitrogen use efficiency. This study was conducted to evaluate nitrous oxide (N₂O) and ammonia (NH₃) emission by mixed treatment of urea and zeolite in upland crop field. Urea fertilizer and zeolite were applied at different rates to study their effect on N₂O emission during red pepper cultivation in upland soils. The N₂O gas was collected by static closed chamber method and measured by gas chromatography. Ammonia concentration was analyzed by closed-dynamic air flow system method. The total N₂O flux increased in proportion to the level of N application. Emission of N₂O from the field increased from the plots applied with urea-zeolite mixture compared to urea alone. But urea-zeolite mixture treatment reduced about 30% of NH₃-N volatilization amounts. These results showed that the application of urea and zeolite mixture had a positive influence on reduction of NH3 volatilization, but led to the increase in N₂O emission in upland soils.
