Lately, concern about removal of base cations from the forest in connection with intensive forest biomass harvesting has become a discussed issue. It is essential to be able to measure or estimate the base cation deposition to forests with a reasonable accuracy. During the 1980s and 90s a great deal of work was performed in order to determine the input of base cations to forests whereas there has not been much new literature since the 1990s. A workshop was arranged November 21-22, 2012 in order to explore the latest developments and advancements within the area. In this report we summarize the workshop outcomes. The importance of combined methods for measuring or estimating base cation deposition was emphasized. European-wide base cation modelled maps seems feasible and was considered desirable.
