This study analysed the effect of organic fertilizer on
greenhouse gas emissions, including carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O),
resulting from paddy field farming. Suphanburi 1 rice varieties were planted in a double-crop
organic rice field at Pathum Thani Rice Research Centre, Pathum Thani Province, Thailand. The
paddy was divided into 4 plots, as follows: (1) control plots without added fertilizer, (2) plots
with the addition of organic fertilizer (cow manure), (3) plots with the addition of organic
fertilizer pellets, and (4) plots with the addition of chemical fertilizers. The results showed
that the CO2, CH4, and N2O emission rates in the chemical fertilizer plot were the highest at
534, 1.79, and 1.21 mg m(-2) day(-1), respectively. The second highest levels were with the
addition of manure at 377, 1.35, and 0.88 mg m(-2) day(-1), respectively. To help reduce
greenhouse gas emissions from rice farming, it is recommended that organic fertilizer be used
instead of chemical fertilizer, a practice that will also benefit the farmers' health.
