Dear Rajpoot, There are many reason to have soil contaminated with Mn, first of all abandoned manganese mine, second, dust fall from ferro manganese plant , third disposal of Fe/Mn from ground water drinking plants.
Dear Ritika,
Manganese is slightly movable in the soil, as compared to elements fixed strongly such as cesium. Much manganese is in the form of oxides in equilibrium with the Mn2+ ions adsorbed on the clay-humic complex or solution (10-6 to 10-4M). The easily extractable fraction of the total manganese of a soil is of the order of percent. Migration depends on soil characteristics: in low cation exchange capacity (sandy acid soils, for example) soils, leaching is moderated; soil or organic matter rich horizons would set low manganese, however, soils rich in clays would set quite strongly manganese. Therefore, the concentrations of manganese soils range from 270-2000 ppm in sandy soils to achieve 525-9200 ppm in clay loam soils.
With my best regards

Dear Rajpoot. We explored moving and acid-soluble forms of manganese in soils of Lviv landfill. Therefore, the content of mobile forms of manganese was 27,84-3141,08 mg / kg, acid-soluble forms of manganese content ranged from 47,31 to 3478,42 mg / kg.
