Studies on the effect of clay and organic matter contents on the determination of cation exchange properties in clay soils by the ammonium acetate and methylene-blue methods
The correlation between CEC-values obtained by ammonium acetate and methylene-blue adsorption methods is relatively good (r = 0.86***). The latter method gives, however, about 30 per cent lower values for exchangeable cations. The extraction ratio used in the dye adsorption method has a clear effect...
