The Association of Manganese and Cobalt in Soils—further Observations

Summary Soil Mn was mineralized either as birnessite or lithiophorite in five out of seven widely distributed soils taken from Bermuda, Europe, and the Middle East countries. The majority of the soil Co was associated with these minerals. This agrees with earlier work on Mn in Australian soils and suggests that these two minerals are the most common soil forms of secondary Mn minerals.
