Mycorrhizal fungi bomb

Welcome to Permies Dana, do i understand correctly you have an indoor worm farm which you feed house compost and add birch shavings?
Do you like to use the end result and spread it on your lawn, flowers and forest?
I wouldn't bother, because lawn and flowers prefer a bacteria dominated soil and forest prefers and creates a fungi dominated soil according to the book teaming with microbes.

Ah, thank you Hugo. I have everything to learn about sustainable ways to increase the health of the soil and therefore all that grows in it.

The aim being to replicate preferred food of a forest floor litter loving worm maintained indoors. Interior AK climate and non-native species.

Wood 🙃 it work to inoculate mesh bags of buried aged wood chips near trees? or could soaking rotten fallen branches with lichen or another fungus on it, then spraying that solution in layers in to the shavings pile work faster?

My goal is to use the granular fertilizer spreader to broadcast worm castings all over my lawn, also out in to trees, before rains. Also add castings to produce and flower garden plants, and house plants.

Mycorrhizae don't live or thrive where there are no living roots, so adding mycorrhizae to wood chips will not have much benefit. While the mycorrhizae will go dormant, which is their survival mechanism,  adding these organisms to living root systems is a far better use.
When wanting to add fungi to wood chips,  mushroom sluries work best, mushrooms are decomposers where as mycorrhizae are not decomposers.

I'm way late to the party.
Awhile ago I cooked rice after watching the video on youtube how to harvest microbes.
I had some water salable mycorrhizae powder I use in the garden.
Indoors I used newspaper. Mixed mycorrhizae powder into the rice and spread the rice (1 inch thick) and coverd it with a sheet of newspaper. I kept the newspaper damp for 10 days and the mycorrhizae growth was awesome!!!
I broke the rice into chunks and dug them in under my avocado trees 3 inches deep. Now when n dig under the mulch (cow manure/wood chips) there is n crazy mycorrhizae bomb going on in my soil!!!

Have been for a forest walk today, took some soil from the roots of, hazelnut tree, oak, wild cherry, alder, aspen, douglas fir, ash tree, beech and hornbeam. A bucket full in total, mixed it with water, gave it a good stir and into the wateringcan it went, spread it all over the productiongarden at all trees and shrubs, in the little tree nursery and in the housegarden.
Young cuttings and trees grape vine, apple etc.
