Abstract

The influence of long-term nitrogen (N) fertilization and climatic drivers on the production and leaching of
dissolved organic carbon (DOC) and dissolved organic nitrogen (DON) was studied in a Norway spruce (Picea
abies (L.) Karst.) forest stand. DOC and DON soil solution concentrations in the O horizon were roughly an
order of magnitude larger than B horizon soil solution concentrations. Soil solution sampled in the O horizon did
not seem to respond to N fertilization. In the B horizon, however, slightly elevated concentrations of DOC and
DON were occasionally observed in the fertilized plots. There did not seem to be a substantial effect of N
fertilization on soil solution concentrations of DOC and DON. A decisive influence of simple climatic drivers on
the within-year dynamics of DOC and DON soil solution concentrations could not be determined in this work.
The annual mean DOC concentrations were higher 2009 than 1995, which might reflect an influence of the tree
stand development on DOC soil solution concentrations.
