| Abstract: |
| Ammonia volatilization is the main pathway of nitrogen loss from paddy, which not only reduces nitrogen use efficiency but also causes serious environmental pollution through the formation of PM2.5 and nitrogen deposition. In this paper, the nitrogen volatilization loss rules and related influencing factors of a paddy field system were reviewed. Additionally, the advantages and disadvantages of the four ammonia emission reduction measures were discussed, such as adjusting the type of nitrogen fertilizer, recycling organic waste, adding soil conditioners, and optimizing water and fertilizer management. These findings summarize the deficiencies of emission reduction in the current research, contributing to future emission reduction in paddy fields. |
