- Intervention effect HNPK increased soil NaHCO3-Po by 83.53% compared with the control (CT) P fractions in a double rice cropping system.
- Intervention effect HNPK increased soil NaOH-Pi by 163.54% compared with the control (CT) P fractions in a double rice cropping system.
- Intervention effect HNPK increased soil NaOH-Po by 183.78% compared with the control (CT) P fractions in a double rice cropping system.
- Intervention effect HNPK increased soil HCl. dil. Pi by 3167.25% compared with the control (CT) P fractions in a double rice cropping system.
- Intervention effect Non-labile soil P was decreased by HNPK addition.
- Intervention effect LNPK increased P uptake and grain yield by 10.02% compared with the control (CT) in double rice cropping (the values are reported jointly for the two outcomes, respectively for LNPK and HNPK).
- Intervention effect HNPK increased P uptake and grain yield by 35.20% compared with the control (CT) in double rice cropping (the values are reported jointly for the two outcomes, respectively for LNPK and HNPK).
- Intervention effect P use efficiency indices were higher under HNPK than under LNPK.
- Association Redundancy analysis showed a strong correlation between soil chemical properties and the labile and moderately labile P pools.
- Mechanism Structural equation modeling indicated that SOM, mineral N and available P strongly control the labile P pool.
