Abstract Carbon and nitrogen are squantitatively important elements in forest ecosystems. Most of the carbon and nitrogen are stored in the soil and have a long turnover time. Only a small fraction of the N-pool is cycled every year through growth and litter fall and mineralisation of litter. Industrialisation has caused high acid and nitrogen inputs to ecosystems which have affected carbon and nitrogen stocks and mineralisation processes in forest ecosystems. In addition, global change of temperature and precipitation will also have a direct influence on carbon and nitrogen cycles in the short-term and on their stocks in the long-term. In order to detect measurable changes in the carbon and nitrogen stocks of forest soils, several decades and sometimes centuries may be needed because they have by nature high spatial variability and occur in large stocks. Therefore, it is very difficult to obtain information on fluxes of these elements by measuring changes in the bulk stocks. Direct measurements of input and output fluxes may provide useful information to assess any changes of the bulk stocks, and on understanding of human-induced changes in the mineralisation processes, as long as the values of input and output fluxes can be accurately measured.
