This study aims to investigate the changes in isotope ratios in foliage and soils of two Norway spruce&nbsp;(Picea abies [L.] Karst.) forests greatly differing in their atmospheric N deposition and climatic conditions. As expected, both N concentrations and &delta;<sup>15</sup>N values in needles and roots were found to be significantly higher in the Solling stand (N-saturated) compared to the Hyytial&auml; stand (N-poor). For both stands a typical vertical gradient of the soil <sup>15</sup>N-enrichment was observed. As expected, the soil of N-polluted site (Solling) was <sup>15</sup>N-enriched significantly more than that of N-limited site (Hyytial&auml;) and this is explained by the presence of marked NO<sub>3</sub><sup>&ndash;</sup> leaching at the Solling site. Although the annual trends (1990&ndash;1994) of N concentration in the foliage of spruce trees remained almost constant, their &delta;<sup>15</sup>N values significantly decreased with the increasing years of sampling. The <sup>15</sup>N-depletion in spruce needle litter from 1990 to 1995 was by 2.0&permil;. This is explained by a slight decrease in N deposition at Solling site during this period.
