Element number 26 in the Periodic Table of the Chemical Elements

A micronutrient important for photosynthesis and the activation of enzymes that trigger different phases in a plant’s life cycle.

This micronutrient activates one or more enzymes in fatty acid synthesis; it also activates the enzymes responsible for DNA and RNA production. Closely associated with copper and zinc, manganese also participates directly in the photosynthetic creation of oxygen from water.
