Soy’s Manganese Deficiency (Mn)

The importance of manganese (Mn): it acts in the formation of chlorophyll, acts in the synthesis of proteins.

It acts on the evolution of oxygen from water (photolysis) in the process of photosynthesis (photosystem II). The symptom of manganese (Mn) deficiency in soybean causes chlorosis between the leaf veins.

Except for the veins, soybean leaves turn pale green and turn pale yellow. Manganese deficiency differs from iron and magnesium in that the veins remain green and appear raised. Also in manganese (Mn) deficiency symptoms are first visible on young leaves, while in magnesium (Mg) the old leaves are the first to be affected.
