Very interesting questions.

Paul Stammets “Fascinating Fungi” documentary was a light interesting watch for the mycillium growth in forest. Certainly you could use the forest timber for creating the break down and environment for fungi growth. We use decomposing sawmill offcuts for that reason on our blueberries. We innoculate strawberries as they are a much shorter growth to production crop. there is an obvious benefit from the innoculants,, and now innoculate the blueberries when planting out. I am also contemplating adding bulk sawdust to a trial field of strawberries and working it into the soil.

As a fast efficient method the innoculants go a long way for the cost here.

watching this thread for answers also. Thanks
