Abstract: 

Using a data set derived from 480 soil samples, pedotransfer functions for the coefficient (K) and the exponent (m) of the Freundlich sorption isotherm were developed. The functions were validated with data from 135 independent soil samples. We found high goodness-of-fit for the approaches of the Freundlich coefficient, whereas the efficiency of the models for predicting the independent samples should be improved. For the Freundlich exponent, the mean value of the parameterisation data set (m = 0.88) served as a better predictor than any of the developed functions. These findings contribute to the interpretation stated by previous authors that variation of the Freundlich exponent is of minor importance and therefore negligible in the course of sorption modelling.
