The mineral content of cereals, grain legumes and oilseed crops in South Australia

Abstract

Samples of barley, oats, lupins, peas, rape, linseed and safflower were analysed at five growth stages for nitrogen, phosphorus, potassium, sulphur, calcium, magnesium, sodium, chlorine, silicon, copper, zinc and manganese. The results are summarized and compared with those for wheat published in a previous paper. The data are discussed in relation to nutrient removal and the effect on soil fertility.
