Other claims from this paper (14)
- Observation Rice yield under different fertilizer treatments ranged from 6.2 to 11.8 t ha−1 in 1984–1995.
- Observation Rice yield under different fertilizer treatments ranged from 7.9 to 12.7 t ha−1 in 1996–2007.
- Observation Rice yield under different fertilizer treatments ranged from 6.6 to 12.8 t ha−1 in 2008–2018.
- Intervention effect Rice yield under NPKM (30% NPK plus 70% manure) was greatly improved compared with other treatments, except NPK in 1984–1995.
- Intervention effect Under PK, NP, NPK and NPKM, soil total P was significantly higher than under CK and NK during 1984–2018.
- Intervention effect Soil pH under CK and NPKM was greatly higher than under other treatments during 1984–2018.
- Intervention effect P uptake under NPKM was significantly higher than under other treatments, except NPK in 1984–1995 and 2008–2018.
- Observation Average PUE (1984–2018) under PK was 10.7 kg kg−1.
- Observation Average PUE (1984–2018) under NP was 20.2 kg kg−1.
- Observation Average PUE (1984–2018) under NPK was 36.1 kg kg−1.
- Observation Average PUE (1984–2018) under NPKM was 44.2 kg kg−1.
- Intervention effect The apparent P balance (APB) under NPKM was significantly lower than under PK, NP and NPK.
- Mechanism Cation inputs from organic manure may be a factor in the increase in soil pH.
- Recommendation Organic manure substitution for chemical fertilizer is a more efficient strategy for increasing PUE and rice yield.
