Go to http://www.treesearch.fs.fed.us/
and author search for 'birdsey' Wealth of U.S. carbon / nutrient cycling research publications. I am sure there are much more on the international front as well but that will take a bit more searching.

The keyword is "island of fertility" if you look for more information and a classical paper on this subject is Zinke PJ (1962) The pattern of influence of individual forest trees on soil properties.
