The aim of this study is to present the new diagnostic method for trophic variants of soil subtypes and its use in forest site cartography. The following groups of sites were studied (look above). Parallel valorization of soil by geochemical properties and by vegetation composition was used in this research. All compounds are expressed as contents in kg per volume of soil 100 x 100 cm and till the depth 150 cm. The discriminant analysis and graphic data analysis have shown that the soil group tested are best divided by: contents (Ca + K + Mg + Na) and others. Defined soil features enabled calculating the level of trophism of a given soil pedon
