Iron and Chromium Uptake by Crops on Well Drained Soils and on Poorly Drained Wetland Soils

In two upland crops, corn (maize) and sugarbeets, a drastic increase in iron content of the above-ground parts was found below a limiting zinc content(18, 11, 24). Above that limit, there was no relation between these two. Only in corn roots, higher iron contents were recorded as zinc contents dropped to a deficiency limit. At still lower Zn contents, iron contents in the roots dropped again, in the same treatments in which a drastic Fe increase occurred in the above-ground parts.
