Thank you for this discussion as I am learning lots!
I guess one of the things that I would like to see is a list of which microbes will benefit which plants.
One of the above refs does say that most of the common veges etc need Endo ones.
Have you come across more specific lists? Which specific microbe for which crop?
Also somewhere I came across the idea that:- yes, strawberries require mycorhizzae, but if peat is used then
the effect of the fungi is reduced?
I suppose this is a new idea to gardeners and the info will come as more of us experiment.
