Short summary

Al toxicity to plants and soil infertility in acidic soils are the main limiting factors for crop growth. To establish which acid soils need to be ameliorated for plant growth, the parameters of critical soil pH and soil Al concentration must be determined. The critical soil pH and exchangeable aluminium of two Ultisols for wheat and canola production were determined in this study. The results obtained will provide useful references for the utilization and management of acid soils.
