Science Buddies: "Ask an Expert"

I am just starting my research about fungi. I just want to ask Can fungi can be a fertilizer? thank you.

Fungi tend not to contain enough nutrients, such as nitrogen or phosphorus, to be useful as a fertilizer. However, there are many well-known symbiotic relationships between plant roots and fungi that are beneficial to the plant. Search for these sets of terms on Google:

mycrorrhizal fungus fertilizer

AM fungi

Half an hour of googling should get you some interesting leads.
