Details are given of a factorial pot experiment in which oat was grown in soil treated with copper and cobalt sulfates, both singly and in combination, at various rates. Copper and cobalt treatments decreased the dry weights of oat tops. They also produced symptoms of iron deficiency in the leaves and a reduction in the total iron status. A significant negative correlation (P = 0.001) was observed between the number of plants per pot showing iron deficiency symptoms, and their Fe status.
