Subsoil aluminium (Al) toxicity or soils with AlCaCl2 content > 2.5 mg Al kg-1 in the soil layers below 10 cm is a significant problem in south Western Australia. Both lime and gypsum can be used to treat subsoils Al toxicity because these products decrease the toxic effect of soil Al leading to an increase in crop grain yields. In this presentation, results are reported from three field lime by gypsum rate experiments located in the east of Merredin.
