Manganese (Mn) is an important plant micronutrient and is required by plants in the second greatest quantity compared to iron. Like any other element, it can have a limiting factor on plant growth if it is deficient or toxic in plant tissue. It is similar to iron in many ways, and manganese deficiency or toxicity is often mistaken for iron ...

A hard, brittle, silvery metal. Uses. Manganese is too brittle to be of much use as a pure metal. It is mainly used in alloys, such as steel. Steel contains about 1% manganese, to increase the strength and also improve workability and resistance to wear. Manganese steel contains about 13% manganese.

Young leaves of Manganese deficient plants exhibit interveinal chlorosis with a relatively wide area of green associated with the veins, but leaves do not become cream color. Leaves, shoots, fruits or stems may be contorted, and plant parts may be reduced in size or have necrotic spots that are tan or gray. Interveinal necrosis or necrotic ...
