Thanks for your reply. Most forest trees, at least in Europe, are
ectomycorhized. Appropriate symbionts are available since a dozen
species of Nothofagus are grown by distributors.

My question is about bacteria and dinitrogen assimilation. No fungus is
able to do that. Symbiotic bacteria help the plant to bypass the need
for nitrogenous organic supplies.
