Abstract:
Nitrogen wet deposition is naturally composed from natural and fertilizer/industrial compounds. We focused on estimations of feedbacks between nitrogen wet deposition (NWD) and the N uptake by floodplain tree species that depend on optimal available nitrogen supply. We estimated The tree wood N uptake from the treering analysis recalculated to the obtained N content in the dry mass. These datasets we compared using 1km grid GIS map algebra over an forested area of the northeast Czech Republic (Central Europe; 6,247 km2; forest cover 21.39%). Present Common ash (Fraxinus excelsior) utilizate about 58.5 t/km2 per year. Willow stands (Salix sp.) utilizate 24.3 t/km2 per year. Potential presented ahswoods on an optimalized area of 2,375 km2 could utilizate upto 1,389 kt per decade while potential willowwoods on 1,177 km2 upto 285.9 kt per decade. 3.3 t/km2 of N per year could fall on ash and/or willow stands. Willows seem to be able to decrease the pressumed N pollution impacts effectivelly for shorttime period while ashwoods for longtime period. However, the tree species pollution bufferpotential is limited due to the overcoming of predicted abovelimit levels of the NWD. A pollution decrease is necessary to continuance in providing of the woods buffer effects.
