Fungi Networks Stretch 100 Quadrillion Kilometers

A new study found that fungi networks in the soil are very long. These fungi help plants grow by giving them nutrients and water. They also help the climate by storing carbon. The study shows these networks are very important for life on Earth.

A recent study has discovered that the underground networks of fungi, known as arbuscular mycorrhizal fungi, can stretch over 100 quadrillion kilometers. These networks play a crucial role in supporting plant life by providing essential nutrients and water in exchange for carbon. They also help regulate the climate by storing carbon in the soil. Despite their importance, the study highlights that little is known about their distribution and density in ecosystems.

A groundbreaking study has revealed that subterranean networks of arbuscular mycorrhizal fungi can extend more than 100 quadrillion kilometers, significantly impacting plant life and climate regulation. These networks, formed over 475 million years, create vital partnerships with over 70% of plants, facilitating nutrient and water exchange for carbon. The research, which utilized machine-learning models and data from over 16,000 soil cores, produced the first global map of these fungi networks. It also raised concerns about the threats posed to these essential systems, particularly in agricultural settings where network densities are notably lower than in wild ecosystems.
