Abstract

In the DIRT (Detritus Input and Removal Treatment) field experiments established at the Síkfo{double acute}kút Site (North Hungary) in October 2000, an experiment was initiated to study the long-term effects of litter quality and quantity on pH and nutrient content (organic carbon, N forms, PO 4 3-, K +, Mg 2+, Ca 2+) of soil in a Quercetum petraeae-cerris forest. An eight-year litter manipulation demonstrated a close connection between the changes in pH and Mg 2+ and Ca 2+ concentration. The decline of litter production, the decrease of the soil pH due to lower Mg 2+ and Ca 2+ input lead to consequent reduction of soil buffering capacity. The acidification interferes with the decomposition process of litter and humus compounds. Our results suggest decreases in organic matter content, total N, Ca 2+ and Mg 2+ concentrations in the soil as a consequence of decline in forest litter production induced by climate change and a resulting degradation of the soil over a longer period.
