%X The effect of soil acidity on barley growth in Western Australia and the role of aluminium toxicity and nutrient deficiencies were examined at 9 sites using 5 application rates of lime and 3 levels of supply of nutrients. Nutrient plant analysis was also used to assess the mechanisms involved in any response to lime.Lime application increased barley yields at 3 sites, by 9-30%, by alleviating aluminium toxicity. Nutrient treatments did not interact with the lime response. The largest reduction in grain yield (>15%) that was due to aluminium toxicity occurred at the site which had the lowest pH (4.3 in 0.01 mol CaCl2/L) and the highest concentration of CaCl2-extractable aluminium (5 µg/g).
