Abstract

Uptake of NH 4 and NO 3 by above ground parts of beech trees was studied by spraying young trees withvarying concentrations of ZSN labeled solutions, different N-forms, and spray regimes over four months.Following treatment, the trees were harvested and analyzed for 15N and major element content.Throughfall was collected and analyzed in addition in order to study the interaction between nitrogenuptake and cation leaching.Significant amounts of N were taken up by the above ground plant parts in all treatments as indicatedby 15N analysis of the trees as well as by throughfall measurements. NH 4 uptake exceeded the uptake ofNO 3 if applied in the same concentration. Uptake of N increased linearly with increasing concentrationin the spray solution and with spray intensity. The uptaken N was translocated within the plant. Thecontribution of N from uptake by above ground parts to the total N content of tissues differed andreached a maximum level of 6% in leaves. No effect of above ground N uptake on the total N contentof tissues was found.Calculating atmospheric N inputs to forest ecosystems by throughfall measurements may underestimatethe actual N input.
