The plant-available P content of soil decreased from nearly 25 mg L1 down to 16 mg L1 with liming, compared to the control
(Table 2).
There were no significant differences in the available P content among the liming materials and the application rates.
Indeed, phosphorus is one of the most important plant nutrients that limits plant growth in acidic soils because P is adsorbed by Fe and Al oxides and hydroxides in these soils (Parfitt, 1989).
