G. Echevarria et al., CHARACTERIZATION OF THE AVAILABLE SOIL NI BY THE ISOTOPIC EXCHANGE KINETICS, Comptes rendus de l'Academie des sciences. Serie II. Sciences de la terre et des planetes, 324(3), 1997, pp. 221-227
The aim of this study was to demonstrate that soil Ni available for pl
ants can be characterized by the isotopic exchange kinetics method. Th
erefore, isotopic exchange kinetics were performed in soil-solution sy
stems to quantify the pool of soil isotopically exchangeable Ni (E val
ue). Another isotopic exchange method in soil-plant systems was design
ed to measure the pool of soil available Ni (L value). Results clearly
demonstrated that the pool of isotopically exchangeable soil Ni for a
given time is the pool of available soil Ni.
