Popis: In the DIRT (Detritus Input and Removal Treatment) field experiments established at theSíkfkút Site (North Hungary) in October 2000, an experiment was initiated to study the long-termeffects of litter quality and quantity on pH and nutrient content (organic carbon, N forms, PO43–, K+,Mg2+, Ca2+) of soil in a Quercetum petraeae-cerris forest. An eight-year litter manipulationdemonstrated a close connection between the changes in pH and Mg2+ and Ca2+ concentration. Thedecline of litter production, the decrease of the soil pH due to lower Mg2+ and Ca2+ input lead toconsequent reduction of soil buffering capacity. The acidification interferes with the decompositionprocess of litter and humus compounds. Our results suggest decreases in organic matter content, totalN, Ca2+ and Mg2+ concentrations in the soil as a consequence of decline in forest litter productioninduced by climate change and a resulting degradation of the soil over a longer period.
