The paper presents a comparison of several empirical models used to determine cation exchange capacity (CEC) and base saturation (BS). CEC and BS determinations in mineral soils in southern Poland have been used in comparisons of individual models. The soils represented different valuation classes and differed in their typology. The following models were used: multiple regression, polynomial neural network and fuzzy-neural network (ANFIS). Models used for comparative purposes represent pedotransfer functions (PTF), developed for various climate conditions using various analytic methods. The processed results were compared with the modelling results based on observational data analysis. Relatively low applicability has been found for models based on data for other climate conditions and other analytical methods in terms of accurate CEC determination.
