Ecological Soil Screening Levels for Manganese

In soils, manganese is known to interact with a handful of other elements. Most prominently, manganese is observed to interfere with the availability of cobalt to plants from soils via a strong affinity of manganese oxides to native cobalt. Also, in acidic soils that contain a large amount of manganese, iron absorption by plants can be affected.
