- Intervention effect Sulfuric acid increased soil ammonium by 5.5-fold.
- Intervention effect Sulfuric acid increased nitrate by 1.5-fold.
- Intervention effect Soil acidification significantly improved rice plant growth regardless of N rate or source.
- Intervention effect Soil acidification significantly improved rice n uptake regardless of N rate or source.
- Intervention effect N application improved plant growth more than acidification.
- Intervention effect N application improved N uptake more than acidification.
- Mechanism Continuous rice yield decline is probably associated with reduced soil N availability and plant N uptake as pH rises.
