Dual deficiency of copper and cobalt in Hawke's Bay

Abstract

Extract

Investigations of difficulties in rearing hoggets and of associated trace mineral deficiency in Hawke's Bay showed the existence of a dual deficiency of copper and cobalt on the soil known as Pakipaki coarse sandy loam.(1) No account of such a dual deficiency in New Zealand has yet been published, and it is considered desirable, therefore, to record briefly the evidence for the existence in Hawke's Bay.
