Other claims from this paper (8)
- Intervention effect Rice nitrogen uptake increased rapidly as N application rose to 225 kg/hm~2.
- Intervention effect Rice nitrogen uptake changed little above 225 kg/hm~2 of applied N.
- Intervention effect A 75 kg/hm~2 N application did not sustain long-term soil fertility for rice growth.
- Intervention effect N supply above 225 kg/hm~2 led to substantial surplus nitrogen accumulation in soil.
- Association N application level correlated significantly with average total N concentration in leakage water, with coefficient 0.943.
- Observation Booting through grain filling was identified as an important period of rice N uptake.
- Intervention effect Soil N accumulation increased rapidly after basal N application.
- Intervention effect Leakage-water N content peaked after basal N application.
