Composted animal manure added for improving soil quality and enhancing crop productivity can lead to greenhouse gas emissions such as nitrous oxide (N₂O) by processes of nitrification and denitrification. In addition, the amount of N₂O emission from composted manure amended soils can vary greatly with composted manure type or different soil type. Therefore, the influence of cattle composted manure on N₂O emissions was evaluated during growth of sweet potato (Ipomoea batatas). The treatments included control, conventional fertilization (CF), and CF + cattle composted manure (CCM) 10 Mg ha-1 were applied in the spring. N₂O emissions were significantly affected by composted manure and chemical fertilizer and the CCM had greater N₂O emissions compared with other treatments. The majority of N₂O emissions occurred shortly after composted manure and chemical fertilizer application compared with the rest of the growing seasons for all treatments. Also, N₂O flux was associated with water-filled pore space (WFPS) at all treatments. On average of N₂O emission accumulation, the CCM was 1.5 times greater than control treatment while there was no difference between CF and control.
