Underground fungal network spanning more than 110 quadrillion km mapped for the first time
Scientists have mapped the global underground network of arbuscular mycorrhizal fungi for the first time. The Science study estimates that fungal filaments in topsoil stretch for more than 110 quadrillion kilometers and weigh about 300 megatons. These networks help plants absorb water, phosphorus, nitrogen, and minerals while also contributing to long-term soil carbon storage, making them an overlooked part of climate and conservation policy.
