Forest soil fertility is generally estimated by studying the water and nutrient cycles essential to living organisms (i.e. biogeochemical cycles). Use of geochemical and/or isotopic tracers is an innovative, complementary approach to more traditional studies. Experimental procedures and results of some recent studies in forest ecosystems using natural tracers (e.g. 18O, 13C, 26Mg) or artificially supplied tracers (e.g. enrichment in Sr, Rb, 15N, 44Ca, 26Mg, 32P) are presented. Results are discussed in terms of relevance for using these tools to identify sources, to estimate residence times of water and elements, and to trace nutrient fluxes, of both organic and mineral origins, that are internal or external to the ecosystem.Read less <
