Le présent document spécifie une méthode de détermination de la capacité d'échange cationique (CEC) et de la teneur en cations échangeables (Al, Ca, Fe, K, Mg, Mn, Na) dans le sol à l'aide d'une solution de trichlorure de cobaltihexammine utilisée comme réactif d'extraction. Pour les sols contenant du carbonate de calcium, une solution de trichlorure de cobaltihexammine saturée en calcite est spécifiée, en particulier pour la détermination du Ca échangeable. Le présent document est applicable à tous les types d'échantillons de sol séchés à l'air qui ont été préparés conformément à l'ISO 11464.
