The calculations of potential denitrification were performed for surface horizons from 672 soil profiles representing 25 main soil units of Polish soils. A proposal of the assessment of potential denitrification rate on the basis of the nitrate content, humus horizon thickness, its bulk denisity and of previously investigated soil redox resistance in the form of indicators t 300 and t 400 is presented. It was shown, that the highest potential denitrification would occur in Rendzic Leptosols and in the soils developed from loses i.e. Phaeozem, Cambisol and Luvisol. Evaluation of spatial distribution of the potential denitrification rate at current nitrate content in mineral soils of Poland has been attempted in the from of a map
