Liming is often applied to alleviate soil acidification and increase crop yield on acidic soils, but its effect on soil phosphorus(P) availability is unclear, particularly in rice paddies. The objective of this study was to examine the effect of liming on rice production, yield and P uptake in a three-year field experiment in a double rice cropping system in subtropical China. We also conducted an incubation experiment to investigate the direct effect of liming on soil available P and phosphatas...
