Mycorrhiza are not a new discovery, nor are soil bacteria playing an imporant role. I'm not sure any of this is really "new".

Amateur cannabis growers have been brewing compost tea to enhance the bacterial/fungal/nematode populations in soil for over a decade.

Even in the world of industrial-scale agriculture no-till with cover crops is becoming increasingly popular.

I'm not sure what new things this research really offers besides perhaps attempts to identify specific fungi / bacteria that can enhance yeilds?
