Some mineral levels in Australian wheat

Abstract

Samples of wheat drawn principally from southern Queensland, but including samples representative of total production in all other States, were analysed for sodium, potassium, iron, manganese, copper and zinc. In comparison with available data for North American wheat, Australian wheat contained on average 40 times less sodium, appreciably less potassium and iron, but similar concentrations of manganese and copper. The importance of these results in relation to grain feeding of sheep and cattle is discussed.
