Manganese - an overview ScienceDirect Topics

Manganese is an important nutrient in soils and can be a limiting factor in plant nutrition. Therefore, it has received considerable attention in the soil science community. Most of this literature focuses on the distribution of available rather than total manganese, which would be of more interest to geochemists trying to reconstruct past soil behavior.
