Glin w glebach i roślinach polan pasterskich Tatrzańskiego Parku Narodowego

The aim of the investigations was to determine the exchangeable Al in the soils of the pastural glades in the Tatra National Park, as well as to estimate the influence of pH reaction of the investigated soils on the Al accumulation in the plant sward of these glades. Aluminium in the soils was determined in the 1 mol KCl solution after the Sokołow method's, and in the plants after the wet mineralization by the ASA method's. The Al accumulation in the sward (the overground parts and roots) of the pastural glades increases together with the decrease of the pH value and the org. C content in the investigated soils.
