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