| Résumé | Studying Ca biogeochemical cycle in the critical zone using Ca isotopes has revealed Ca isotope fractionation mechanisms associated to biological (Ca uptake by roots and within-tree translocation, Ca recycling by vegetation) or abiotic (secondary mineral precipitation, adsorption) processes. Ca isotopes have thus shown their potential to trace Ca cycling processes within the tree, Ca uptake mechanisms within the rhizosphere, Ca recycling by the vegetation; Ca isotopes can also be used as a time integrated vegetal turnover marker or as a hydrological tracer. |
