A worker walks past plants covered with ash after Taal Volcano's eruption. Soil scientists point to Arbuscular Mycorrhizal Fungi (AMF), fungi that are of the highest concentration on this planet in volcanic ash, and which constitute a group of root "obligate biotrophs". These fungi exchange mutual benefits with about 80% of plants and are considered natural "biofertilizers", since they provide the host with water, nutrients, and pathogen protection, in exchange for photosynthetic products. Arbuscular mycorrhiza (AM), considered the most common symbiotic association of plants with microbes, helps improve plant nutrition, stress resistance and tolerance, soil structure and fertility.
