Abstract Mollisols-aka, Black Soils or Prairie Soils-make up about 916 million ha, which is
7% of the world's ice-free land surface. Their distribution strongly correlates with native
prairie ecosystems, but is not limited to them. They are most prevalent in the mid-latitudes of
North America, Eurasia, and South America. In North America, they cover 200 million ha of
the United States, more than 40 million ha of Canada and 50 million ha of Mexico. Across
Eurasia they cover around 450 million ha, extending from the western 148 million ha in …
