Regenerative agriculture advocates would argue that cultivating a permanent mycorrhizal fungi ecosystem in fields will lead to longer term yields and few if any inputs in the end. Adding a fungal product into a system that wasn't already conducive to natural growth seems like a recipe for minimal benefit.
For anyone not familiar, look up Gabe Brown's talks on growing soil.

They should show up with data. My other concern is that regenerative farming advocates always seem to leave out labor inputs.
Gabe Brown says he uses cover crops, pastured poultry, and managed grazing on the same land as his primary crop and gets more calories per acre than monoculture farms, but also he has no chemical inputs, his soil is getting richer, and there's far less impact on the environment. And it's not like he doesn't have large farming equipment to do the work with. There's a learning curve and a risk factor in switching, but the alternative is to be dependent on variable fertilizer costs and government subsidies forever while the soil is depleted.
A lot of this is not about increased yield, but healthier more nutritious plants, a healthier soil that binds more carbon, a more diverse farmland supporting a more diverse set of insects and animals and so forth.
The monocropped modern agriculture is not only producing dead soil, farmers that become reliant upon exterior input supplied by global conglomerates (i.e. ther margins don't go to the person doing the farming, but everyone suppling the stuff the farmer needs), and causes a lot of damage to local ecosystems.
> healthier more nutritious plants
No data I’ve seen supports that claim. In fact Vaclav Smil’s book “How to Feed the World” collects a lot of data refuting this claim.
> producing dead soil
If less land needs to be under cultivation this doesn’t matter. You can rewind or reforest old disused agricultural land.
