      abstract = {Cropping on yellow earth soils in the eastern wheatbelt of  Western Australia can be restricted by subsoil acidity.  There are approximately one million hectares of yellow  earth soils in Western Australia, some of which are  extremely unproductive due to acidity and high  concentrations of available aluminum. The best crop  rotation on yellow earth soils includes wheat and  narrow-leafed lupins, but this is not economically viable  on those soils with high aluminum concentrations. It is  known that the yellow lupin (Lupinus luteus) is more  tolerant to toxic levels of subsoil aluminum than the  narrow-leafed lupin (Lupinus engustifolius). Research has  shown that the yellow lupin has a very high level of  resistance to Pleiochaeta root rot and brown leaf spot  (Pleiochaeta setosa) compared to the narrow-leafed lupin.  Evidence from field trials has shown that the advantage of  the yellow lupin over the narrow-leafed lupin is the  greatest on the soils with a high level of extractable  aluminum. The potential role of yellow lupins in the  Western Australian eastern wheatbelt farming system is  assessed using the whole farm bio-economical model, MIDAS  (Model of an Integrated Dryland Agricultural System).},
