What I've learned from the thread is that myco.. is something with beneficial fungi and inoculants are beneficial bacteria.
Our soil is landfill, stuff excavators dug up. So I think it lacks in both, bacteria and fungi.
There's an Australian source for the fungi, it seems quite expensive: mycoapply
I did not find a source for inocculants for home gardeners though.
I wonder weather one could rely on something homemade for both?
And once you have applied that stuff the bacteria and fungi should be happy and procreating?
