A global estimate of plants and their root fungi shows how agriculture may have greatly affected soil carbon storage over time!

Microbe of the episode: Rhizobium virus RHEph4
Knowing how big an effect a given kind of organism has requires knowing how much of it is around. This study collates data from various surveys of global plant populations and the fungi that interact with their roots, to estimate a global picture of the fungi below our feet. It estimates that a kind of fungus that stores more carbon in the soil may have been replaced in many areas with fungi that store less, or no fungi at all, due to the transformation of land from wild areas to farmland.
