There are many variables involved. The rooting diameter various from species to species for one thing. Half the nitrogen returning to the system is via leaf litter so how far that goes depends on height, exposure etc. Most important of all is probably the status of the mycorrhizal fungal system as this can move nitrogen significant distances.
