Abstract

In the DIRT ( Detritus Input and Removal Treatment ) field experiments established at the Síkf ő kút Site (North Hungary) in October 2000, an experi ment was initiated to study the long-term effects of litter quality and quantity on pH and nu trient 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 s oil pH due to lower Mg 2+ and Ca 2+ input lead to consequent reduction of soil buffering capacity. Th e 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 dec line in forest litter production induced by climate change and a resulting degradati on of the soil over a longer period
