This research study aims to determine the production of nitrous oxide (N 2 O), carbon dioxide (CO 2 ), the rate of ammonium-nitrate, microbe responses in soil following the addition of urea coated by zeolite under soil incubated. The result showed that urea granulated with zeolite in soil sample had a significant effect on the production of CO 2 and have no significant increase N 2 O productions. Therefore, the addition of urea with zeolite seems to decrease the production of N 2 O compared to urea alone. The concentrations of ammonium and nitrate during incubation time were significantly affected by the amended type of fertilizers. The availability of ammonium and nitrate in soil were increased by addition of urea zeolite 30%. The urea combinedzeolite increases the growth of the fungi population, while population of ammonium oxidizer bacteria seems appearedlower in soil that amended with fertilizer compared to the control. The study showed that urea granulated with zeoliteincreased the time availability of soil nitrogen.
