On acid soils, the trivalent aluminium ion (Al3+) predominates and is very rhizotoxic to most plant species. For some native plant species adapted to acid soils including tea (Camellia sinensis), Al3+ has been regarded as a beneficial mineral element. In this study, we discovered that Al3+ is actual...
