abstract
This paper presents the results of statistical-physical modelling (pedotransfer function) relating soil water content at defined values of soil water potential to selected physical and chemical parameters of organic soils. The two models were developed as the result of the modelling. The independent variables of equations of both models are: ash content, specific surface area, bulk density, pH in KCl and Fe content. The following ranges of determination coefficient values between the measured and predicted water content were estimated for the models: 0.67 < R2 < 0.81 for the first and 0.68 < R2 < 0.91 for second one.
