In episode 8 of Corn College TV, Ken Ferrie explains that although they aren’t need in large quantities, micronutrients play a big role in plant health.

“The term micronutrient doesn’t mean they aren’t important,” Ferrie says. “It just means we don’t need the large quantities like we apply in nitrogen, for example.”
Micronutrients play key roles in specific functions in the plant.
Ferrie says that micronutrients deficiencies often means there is another issue causing the problem.
“Having a deficiency, typically means there’s an underlying problem. For example, an excess of something else can cause a micronutrient deficiency, or it could be a common issue in a certain soil type or influences by pH,” he says.
