We do a good line in dairy in NZ-I can buy inoculated clover, alfalfa etc but trees...not so much

here's one article. It's actually not as unequivocal as other I've read, but of course I can't find them now

I've exchanged emails with a rhizobia guy; I will probably hassle him some more...

I guess it could, although I'd be pretty surprised.

No I don't, but I've always been taught that a sustainable food forest needed efficient nutrient cycling

fear not, it's not exactly consuming me!

I'm very much with you on this and I've been mulling it over for a while.
