>> Christian Giardina and I are preparing a chapter for the upcoming book: >> Management of Soil, Water, and Nutrients in Tropical Plantation Forests >> (edited by Sadanandan Nambiar and Alan Brown) -- our chapter is on use of >> N-fixing trees. We've scoured the literature that is readily available to >> us, but have found little information on some key features. We would be >> interested in hearing of any studies (especially grey literature, station >> reports, etc.) that deal with the issues listed below. If you know of a >> study, you could e-mail me to see if we've already included it, and if not, >> then I could ask for more information. If you have a strong interest in >> this overall subject, we have a reveiwable draft ready, and would be happy >> to mail a copy for your comments. NOTE: the scope of the chapter is solely >> tropical tree plantations, not native (semi-unmanaged) forests or agroforestry. >> >> We are especially anxious to locate more information on: >> --growth comparisons between N-fixing and non-N-fixing species on the same >> sites; >> --effects of N-fixers and non-N-fixers on soil chemistry, especially any >> second rotation studies; >> --in-field estimates of N-fixing rates; and >> --fertilizer studies that examined nutrient limitations in plantations of >> N-fixing and non-N-fixing species on same sites. >> >> Thanks very much! >> Dan Binkley >> Department of Forest Sciences and >> Graduate Degree Program in Ecology >> Colorado State University >> Ft.
