| Nitrate not taken up by plants or denitrified migrates to streams and groundwater. |
| From there it could be denitrified into simple N, and emitted into the atmosphere, but the ultimate fate of that accumulating nitrogen remains unclean. |
| Under these circumstances, nitrogen is buried rather than denitrified and there is a significant release of ammonia to the water column. |
| During gas fuel or denitrified fuel combustion, thermal NOx and prompt NOx are produced. |
