hello, you could try alder, a species common to europe.
Species:Alder, Alnus glutinous (fens and by fresh water)
Grey Alder, A. incana (drier places)
Green Alder, A. viridis (Mountains)
This tree is definately a nitrogen fixer. the boost in growth rates is easily
seen when comparing alder with other trees in a mixed stand of similar age. No
doubt some of the nitrogen fixed by the alder is made available through the
interconnected web of life of roots and fungi, plants and animals to the whole
woodland ecosystem. mother earth is alive!
apologies for the demon advert below which i cannot remove, but ihope the above
info is useful. regards, jim.
