Answer: Answer: I am not sure what this question is asking. Probably reading the answers to all the
other questions on the Agpath website will provide the information required. Mycorrhizae
are specialised fungi that have a mutualistic relationship with most living plants providing
the plants with phosphorus, for example, and receiving nutrients/carbohydrates in return.
Mycorrhizal fungi will not be found in composts because that is dead plant material. The
fungal strands/hyphae seen in good compost belong to saprophytic fungi which live on dead
and dying plant material.
Fungal/bacterial ratios in compost or soil depend on the plant system. Annual species tend to
have a bacterially dominated soil and perennial plants are fungal dominated by preference.
