Manganese (Mn) is a hard, whitish-gray metal not found in its pure form in nature. It can exist as seven isotopes, one stable, five short-lived and one long-lived (~3.7 million years). It was discovered in 1774 and was named from the Latin word for “magnet.” Manganese is similar to iron in that it will rust. It is used in steel making, as a glass colorant, and in batteries. Manganese is taken up in a tree as the ion Mn++. Other manganese ions in a soil are converted to Mn++ for uptake. Figure 1. Manganese is a metal used in small amounts, but essential to a number of key processes in trees.
