Daftar Isi:
- Agriculture accounted considerably to the greenhouse gases emission such as N2O and CH4. The aim of study is assessing reduction of N2O and CH4 emissions from corn field fertilized with urea granulated nitrification inhibitor namely dicyandiamide (DCD) and neem (N) and zeolite as slow release media. The results show that nitrification inhibitors and zeolite is reducing both N2O and CH4 emissions from corn field fertilized. We observed that the application of urea (U) with dicyandiamide (UD), U with zeolite (UZ), U with neem (UN), U with zeolite+neem (UZN), and U with zeolite+ DCD decreased the N2O emissions by 86.73%, 59.65%, 16.38%, 66.85%, and 81.94%, respectively. Therefore, larger reduction of N2O emission in corn field was applied by UD. However, applying UD in field seems nhance CH4 emission 0.95 kg CH4-C ha-1 season-1 compared to other treatments. The observations should be further being tested to an integrated abatement of agricultural nitrogen as well as carbon losses.
