Soil and Applied Manganese (A2526)

MANGANESE REACTIONS IN SOILS In soil, manganese occurs as exchangeable manganese, manganese oxide, organic manganese, and a com-ponent of ferro-magnesian silicate min-erals. The manganese ion (Mn++) is similar in size to magnesium (Mg++) and ferrous iron (Fe++) and can substi-tute for these elements in silicate min-erals and iron oxides.
