Other claims from this paper (16)
- Observation Plant and soil microbial N fixation, soil organic and inorganic N, NH3 volatilization and N leaching were key factors affecting SPNP and NUE in rice fields.
- Intervention effect SCN at 100–150 kg N ha −1 minimized organic and inorganic N loss relative to the other practices.
- Intervention effect SCN at 100–150 kg N ha −1 increased soil and plant N fixation relative to the other practices.
- Intervention effect SCN at 100–150 kg N ha −1 yielded the lowest SPNP and NUE among the practices.
