Story: Diseases of sheep, cattle and deer

Cobalt-deficient areas

Cobalt-deficient areas

The largest area of cobalt deficiency in New Zealand is the Volcanic Plateau of the central North Island, where volcanic pumice soils are deficient in cobalt. This led to the problem of bush sickness in sheep and cattle, before its cause was identified and corrected. Today, other smaller areas in New Zealand have developed cobalt deficiency under high-production farming.
