Socioeconomic changes in Central Europe have been accompanied by abandonment of previously managed meadows in mountain regions. Among others influences, alteration of N-cycling through such a land-use change may be reflected in N rhizodeposition including proteinaceous compounds. In this work we have determined no significant (P>0.05) effect of 15 year abandonment of previously long-term mown mountain meadows on total protein flow in the form of water-soluble root exudates in mineral soil of 3–8.5 cm depth. Throughout the vegetation season, 6–21 mg N per square meter was deposited every sampling occasion in exuded total proteins on both types of meadows.
