trace element
Tiny essential nutrient
A trace element is a chemical element required by living organisms in extremely small amounts—iron, zinc, copper, and others essential for biological processes.
In chemistry and geology, trace elements are those present in minute concentrations, often measured in parts per million.
The soil was deficient in several trace elements.
