Other claims from this paper (9)
- Observation Blended CRN nitrogen release satisfied rice growth demand.
- Method / resource A quadratic equation modeled the rice yield response to blended CRN nitrogen rate, similarly to conventional fertilizer.
- Intervention effect Blended CRN increased rice NUE by 6.9-14.8% compared with conventional fertilizer at equal nitrogen rates.
- Association Increased NUE under blended CRN was related to reduced ammonia volatilization.
- Intervention effect Modeled five-year average rice NUE at maximum yield under blended CRN was 42.0%, 28.9% higher than conventional fertilizer.
- Intervention effect CRN180 had the highest rice yield and net benefit in 2019.
- Recommendation The optimum economic blended CRN nitrogen rate in the Chaohu watershed was 180-214 kg/hm2, compared with 212-278 kg/hm2 for conventional fertilizer.
- Intervention effect Blended CRN improved rice economic income.
- Intervention effect Blended CRN decreased ammonia volatilization and negative environmental outcomes.
