Leaf litter decomposition of two species; common beech (Fagus sp.) and butterbur (Petasites spp.) was investigated during 2007 in lakes of Plitvička jezera national park. Data on decomposition rate were gathered for the whole year exposition as well as for two short experimental series using the methods of “leaf packs”. Leaf litter of butterbur, as herbaceous plant, showed faster decomposition compared to leaf litter of common beech, which, as woody species, have higher proportion of lignin making the process of decomposition slower. On both species nitrates were absorbed during cold seasons, while process of leaching dominated during warm seasons. Generally, the beech leaf litter had lower content of nitrates. Concentration of phosphates mainly increases with exposition time on butterbur leaf litter, while they were mainly leached from beech leaf litter. Difference in the activity of microorganisms during the year, mainly influenced by water temperature is a possible reason for observed trends.
