Other claims from this paper (6)
- Association Shifting the growth stage of rice plants did not shift the CH4 emission maxima.
- Observation The first CH4 emission peak was attributable to rice straw carbon.
- Observation Three CH4 emission peaks corresponding to the peaks of air temperature were detected for RS-applied pots placed outdoors.
- Association The three CH4 emission peaks were not observed or much less conspicuous for RS-applied pots in a phytotron at 30°C.
- Association Temporal decreases in CH4 emission were detected in phytotron and outdoor pots just after topdressing of (NH4)2SO4.
- Mechanism Topdressing of (NH4)2SO4 is considered a major cause of irregular disagreement between CH4 emission rates and air temperature variations.
