Plant-fungus Symbioses Help Sequester Carbon in Soils

The International Institute for Applied Systems Analysis reports on a study published in the journal Nature Communications that found human impacts have greatly reduced plant-fungus symbioses, or mycorrhiza. These play a key role in sequestering carbon in soils, encompassing storage of some 350 gigatons of carbon globally. Researchers say that restoring these mycorrhizal ecosystems more broadly could help slow climate change, and they suggest restoring native vegetation to abandoned agricultural and barren land to enhance soil carbon storage.
