MANGANESE (Mn) 54.93 Atomic Weight

(Micro Nutrient)

Manganese, combined with other elements, is widely distributed in the earth’s crust.  Manganese participates as an activator for enzymes in growth processes in plants, animals and humans where it helps break down carbohydrates.  It may be essential for the utilization of Vitamin B.  It assists Iron in chlorophyll formation, and helps in the metabolic reduction of nitrates in green plants and algae.  High Manganese concentration may induce Iron deficiency and is generally toxic to plants and humans in excess levels.  Manganese uptake is primarily in the form of the ion (Mn++).
