A determinação da capacidade de troca de cátions do solo e de argilas por meio da troca isotópica com cálcio radioativoThis paper describes the determination of cation exchange capacity of soils and clays, by the isotopic exchange method with radioactive calcium. A sample of 5 grams was used for soils and a 1 gram sample for clays. Eight soilsand four clays were studied and five replications for each sample were analysed. The data obtained were:
