AbstractIn this paper, the current problem associated with the classification of brown earths are presented. According to the Polish Soil Classification (PSC) (1989,2011), base saturation is the main parameter for identifying eutrophic and dystrophic brown soils. However, in practice it is not possible to determine the base saturation value in the field. However, in practice it is not possible to determine the base saturation value in the field. Therefore, the aim of this study was to estimate the base saturation value in the field. Therefore, the aim of this study was estimate the base saturation using a regression equation and create a field guide for brown earths, based on the pH value measured using a Hellige indicator, and the calcium carbonate content. Determination of the pH ranges enable the classification of brown earth types in the field. These results suggest that pH can be used as a proxy for base saturation, especially in the field. A change in the hierarchy of soil (sub)types is proposed for the new Polish Soil Classification.
