Abstract:
It is commonly believed that nitrification is the dominant process for N 2 O production under aerobic conditions. However, this has been challenged by recent studies on acidic soils, where denitrification has been found to dominate N 2 O production. Analyzing the data collected from peer‐reviewed literature, we found that pH was a critical factor regulating N 2 O production pathways under aerobic conditions. There is a pH threshold of approx. 4.4, below which denitrification dominated N 2 O production and vice versa . A decrease in soil pH can significantly increase the contribution of denitrification to N 2 O production. Overall, this mini‐review increases our understanding of N 2 O sources in soils under aerobic conditions.
