Abstract
Temporal variation in two soil tests ([Al] and the ratio [Al]:[Na] in 1:5 0.005M KCl extract) and pH were evaluated on six occasions during a twelve month study of eleven yellow earths in the Merredin region (31°5, 118°E) of Western Australia. The [Al] and ratio [Al]:[Na] in 1:5 0.005M KCl extracts are useful soil tests capable of distinguishing between productive and non-productive (Al toxic) yellow earths in Western Australia. The aim of the study was to determine the most appropriate time to sample yellow earths, in order to predict accurately which soils contained concentrations of Al in the 15-25 cm layer that were toxic to wheat. The concentration of Al differed (p
