Malic acid has been implicated as an inducible root mechanism for the detoxification of rhizotoxic Al. The chemical reactions of malate were therefore investigated in four acid soils ranging in pH from 4.30 to 5.00. All the soils behaved similarly, with malate predominantly complexing Al in solution in favor of other metal cations (Fe, Mn, Cu, Zn, Ca and Mg). Comparison of experimental extraction results with theoretical predictions made using Geochem-PC showed a similar agreement, indicating… CONTINUE READING
