Abstract

The effect of chemicals stimulating tapping on trees mortality, current increase in output by volume and commercial assortments yield has been analysed. The use of 50 % and 75 % sulfuric acid causes trees mortality increase (up to 15 % for 10 year period). With proper tapping methods used, the decrease in current growth increment is small and timber output does not change significantly.
