Abstract
A mathematical model for carbon and nitrogen turnover has been used to investigate the long term consequences of whole tree harvesting (WTH). A number of scenarios of nitrogen deposition and harvesting have been analyzed. The results of the simulations show that the timber production as well as the nitrogen leakage increase strongly with higher nitrogen deposition. The increase in nitrogen leakage will probably be reduced through WTH, but this forecast is uncertain due to other factors. The losses of other nutrients; phosphorus, potassium, calcium and magnesium, increase strongly through WTH. This, together with the ongoing losses of base cations caused by the sulphur deposition, speak against WTH. However, if losses of nutrients can be compensated satisfactorily by return of wood ash and/or fertilizer, WTH may be a possible way to reduce the long term accumulation of nitrogen in the soil. (18 refs., 3 figs., 5 tabs.).
