It also supports the movement of Iron in plants.

Deficiency Symptoms

Manganese deficiency symptoms are first visible in younger leaves.

Newer leaves first become pale green and then turn pale yellow.

It leads to interveinal chlorosis and netveined leaves.

Plants like Banana with leaves that have parallel veins develop a general chlorotic condition.
