abstract in English:	IN the course of a two year investigation of a litter decomposition in the beech-pine forest in the Ratanica watershed (Southern Poland), organic matter mass loss of 44% and 41% was established on the experimental plots A and B respectively.The decomposition rates k were -0.258 and -0.266 for the plots A and B respectively.The concentration of majority of the chemical elements increased in the course of the two year decomposition.The decrease in concentration was observed only for K and Mg on both plots, for P on plot A and for Cu on the plot B.Nutrients can be ordered into a following sequence with respect to their release rate from litter plot A: K more than P more than Mg organic matter = C more than Ca more than S more than Na more than N, plot B: K more than Mg more than organic matter = C more than Ca more than Na more than P more than N.After the two year decompositoin differences between the two plots in concentration of majority of nutrients decreased significantly; a similar tendency was not, however, observed for majority of the heavy metals.A fast increase of the heavy metal concentration was observed in the course of litter decomposition.
