A start-up has begun planting fungi and other microbes in soil harvested from intact forests at a plantation in Georgia. Efforts to “rewild” the soil microbiome may help grow healthy trees that store more carbon.
Fungi and other microorganisms in soil are important factors for tree growth and health. For example, many species of mycorrhizal fungi have evolved to form symbiotic partnerships with specific tree species, helping roots access nutrients in exchange for carbohydrates produced by the tree.
