Nitrous oxide (N2O) fluxes from rice paddy fields were measured in Nanjing, Yingtan and Fengqiu, using closed chamber method in 1994. The results showed that N2O fluxes varied temporally, spatially and geographic regionally, with the total amounts of N2O emissions during the period of rice growth ranged from 13.66 to 98.11mg/m2 in Nanjing, 1.73 to 3.65mg/m2 in Yingtan and 178.04 to 472.26mg/m2 in Fengqiu, respectively. Soil water regime and soil texture had significant effects on N2O production… CONTINUE READING
