Other claims from this paper (18)
- Intervention effect NPK significantly increased rice grain yield by 67.1% compared with CK.
- Intervention effect NPKM significantly increased rice grain yield by 88.1% compared with CK.
- Intervention effect NPKS significantly increased rice grain yield by 84.2% compared with CK.
- Intervention effect NPKM rice yield was significantly higher than NPK.
- Intervention effect NPKS rice yield was significantly higher than NPK.
- Intervention effect Fertilization improved topsoil organic carbon contents by 8.9%-36.8%.
- Intervention effect NPKM topsoil organic carbon content was significantly higher than NPKS and NPK.
- Observation Organic carbon contents increased by 1.84-5.26 g/kg in all treatments relative to initial soil conditions.
- Intervention effect NPKM carbon sequestration rate was significantly different and 2.38 times CK during double cropping rice years using ten-year assessment periods.
- Intervention effect NPKS carbon sequestration rate was significantly different and 1.98 times CK during double cropping rice years.
- Intervention effect NPKM carbon sequestration rate was significantly different and 1.59 times NPK during double cropping rice years.
- Intervention effect NPKS carbon sequestration rate was significantly different and 1.32 times NPK during double cropping rice years.
- Association Annual organic carbon input had a very significant power function relationship with paddy ecosystem carbon sequestration.
- Association Fertilized soil organic carbon contents correlated very significantly with rice grain yields.
- Intervention effect Long-term no fertilizer is interpreted to maintain a slight increase in soil organic carbon.
- Association Soil carbon sequestration efficiency decreases as soil organic carbon content increases.
- Recommendation The authors endorse chemical fertilizer plus cattle manure as a measure to improve productivity and fix carbon compared with chemical fertilizer alone.
- Recommendation The authors endorse chemical fertilizer plus straw as a measure to improve productivity and fix carbon compared with chemical fertilizer alone.
