- Intervention effect Reducing P fertilization to 30.6 kg ha -1 maintained maize yield, grain P content and aboveground P uptake compared with the farmer practice.
- Intervention effect Banded application of single superphosphate (BP) significantly increased maize yield compared with broadcast single superphosphate (RF) over two years.
- Intervention effect The AS treatment lowered rhizosphere pH in maize.
- Intervention effect The AS treatment enhanced the labile P pool in maize rhizosphere soil.
- Intervention effect The AS treatment improved root morphology in maize.
- Intervention effect The AS treatment promoted P uptake in maize.
- Association Root traits at the V3, V10 and R1 stages were positively correlated with β-1,4-N-acetylglucosaminidase activity, phosphatase activity and NH 4 + -N availability in maize.
- Observation Soil available P was identified as the primary determinant of maize yield and P uptake by random forest and Mantel analyses.
- Mechanism The AS treatment enhanced maize yield chiefly via its effects on soil available P, enzyme activity and root traits, according to PLS-PM.
- Intervention effect A 42 % reduction in P fertilization combined with banded superphosphate and ammonium sulfate enhanced maize yield.
- Intervention effect The combined low-input P strategy improved P use efficiency in maize.
- Intervention effect The combined low-input P strategy optimized soil conditions under maize dryland farming.
