Mycorrhizal fungi colonising a host plant’s root tissues

A start-up has begun planting fungi and other microbes in soil collected from intact forests at a tree plantation in the state of Georgia. The effort to “rewild” the soil microbiome may help to grow healthier trees that store more carbon.

Fungi and other microbes in soil are important factors for tree growth and health. Many species of mycorrhizal fungi, for instance, have evolved to form symbiotic partnerships with certain tree species, helping roots access nutrients in exchange for food in the …
