You're packing a ton of great information into your videos. I'm impressed. There are lots of different species of mycorrhizal fungi and each species can have a limited range of plants that they will associate with. I looked up the fungus type in Mykos (Rhizophagus intraradices) and found some scientific literature suggesting this fungus does associate with tomatoes. The fungus is helpful in drought conditions, so new food forests that don't have as much water retention capacity would likely benefit greatly from this hack you are recommending.

This source refers to the drought-tolerance attribute of having mycorrhizal fungus associate with tomatoes.
