As part of the multifunctional research of the ICP program for forests (international cooperation program for monitoring the state of forests in Europe) since 2003, continuously is conducting lysimetric method of monitoring the state of soil solution in forest ecosystems in Serbia. This method covers several forest communities in different ecological conditions. Certain amounts of atmospheric sediment that seep through the soil are collected in gravity lysimeters, which are placed in the vertical front wall of the existing pedological profiles, at a constant depth below the humus horizon. As a filter in a plastic container, there is annealed quartz sand for the purpose of purifying soil solution from soil particles. Sampling is done once a month. Based on these samples, the analysis of soil solution determines the presence of certain nutrients (K, Ca, Mg, Na, N-NO3, S-SO4, N-NH4, Cl) and changes in their concentrations in solution, in order to define the existing vitality of forest complex, as well as in noticing differences in the resistance of certain tree species to the lack of these nutrients. One of the goals is to determine the trend of soil acidification, and the quality of water circulating through a forest ecosystem. In that way, it is possible to determine the buffer capacity of the soil and the extent to which acidification occurred. Monitoring with this method should be extended to other important forest communities in Serbia, primarily oak communities, in order to gain better insight into the impact of forest cover composition on the characteristics of the soil solution, as well as the state of soil damage.
