Trace element concentrations in winter cereals under intensive cultivation



Winter wheat and barley shoots sampled at the tillering stage from 12 farms in two intensive cereal production areas of Northern Ireland were analysed for trace elements B, Co, Cu, Fe, Mn, Mo and Zn plus Ca and Mg. Soil pH values were also determined for each field. Shoot concentrations of all elements were normal except for five fields of winter wheat which initially showed low Mn concentrations but exhibited normal levels when re-sampled 5 weeks later. None of the plants showed deficiency symptoms for any element. Significant correlations were found between shoot concentrations of some nutrients and soil pH and their significance is discussed.
