Abstract
A statistical relation between NO3--fluxes with seepage and runoff, C/N ratios of the humus layer andN fluxes in throughfall was established using data from 16 european Norway spruce sites. The C/Nratio of the humus layer is negatively correlated with the NO3- output. The prediction of NO3- outputis further improved by including the N flux with throughfall as an independent variable. The observedrelation may be used for extrapolation to larger areas; however the range of uncertainty of the calculatedNO3- output is about _+0.5 kmol ha-1 yr-1.
