If there is a deficiency of any essential element, plants cannot complete their vegetative or reproductive cycles and as result will express deficiency symptoms. Some elements like N, S, Mo delay flowering if their concentration in plants is low. An alternative way of monitoring preclinical stages of a trace element deficiency is to identify and measure a biochemical indicator that reflects changes in the activity of an enzyme involved in a key metabolic pathway, such as vitamin B 12 or glutathione peroxidase, which are indirect measures of cobalt and selenium nutrition in sheep, respectively.
