“…The maximum simulated net annual mineralisation, 89 kg N ha 1 a 1 , occurred three years after clear-cutting. These results fall within the range reported for Scandinavian forest soils, 0 110 kg N ha 1 a 1 (Persson and Wirén, 1995;Persson et al, 2000;Andersson et al, 2002). studied the effects of N addition on N cycling in three Swedish catchments of mature Norway spruce stands; the addition of N increased the assimilation by soil and microbes to 83 kg N ha 1 a 1 and net mineralisation to 75.5 kg N ha 1 a…”

“…Experimental quantification of N release from organic material is rather problematic because several processes affect the net N release, including mineralisation, nitrification, denitrification, microbe assimilation and uptake (Persson et al, 2000). Comparison of experimental N release studies is not always straightforward because measurement methods often differ (Staaf and Berg, 1982;Berg, 1988;Hasegava and Takeda, 1996;Devito et al, 1999;Andersson et al, 2002;Bengtsson et al, 2003;Vestgarden et al, 2003).…”

A two dimensional model, FEMMA, to describe water and nitrogen (N) fluxes within and from a forested first-order catchment (Kangasvaara in Eastern Finland) was constructed by linking the most significant processes affecting the fluxes of water, ammonium, nitrate and dissolved organic nitrogen along a hillslope from the water divide to the stream. The hillslope represents the average flowpath of water in the catchment and the model was used to estimate the N fluxes for a catchment in eastern Finland before and after clear-cutting. The simulated results were in reasonable agreement with the nitrate, dissolved organic N and dissolved total N measurements from the study catchment and with other results in the literature. According to the simulations, the major sinks of N after clear-cutting were immobilisation by soil microbes, uptake by ground vegetation and sorption to soil. These sinks increased downslope from the clear-cut area, indicating the importance of an uncut buffer zone between the stream and the clear-cut area in reducing N exports. The buffer zone retained 76% of the N flux coming from the clear-cut area. Nitrification was a key process in controlling the N export after clear-cutting and N increases were mainly as nitrate. Most of the annual N export took place during the spring flood, when uptake of N by plants was minimal.

“…They found that at low C/N ratios below 15-20 other parameters such as climate, pH and groundwater tables increase in importance as predictors for N 2 O emission. A similar negative relationship was found between net nitrification and C/N ratio in spruce and beech forests throughout Europe (Persson et al, 2000). In the study it was also found that no net nitrifcation could be detected when the C/N ratio exceeded 28 which is consistent with the low emissions found from the soils in San Rossore and Hyytiälä.…”

Abstract. Soil emissions of NO and N 2 O were measured continuously at high frequency for more than one year at 15 European forest sites as part of the EU-funded project NOFRETETE. The locations represent different forest types (coniferous/deciduous) and different nitrogen loads. Geographically they range from Finland in the north to Italy in the south and from Hungary in the east to Scotland in the west.The highest NO emissions were observed from coniferous forests, whereas the lowest NO emissions were observed from deciduous forests. The NO emissions from coniferous forests were highly correlated with N-deposition. The site with the highest average annual emission (82 µg NO-N m −2 h −1 ) was a spruce forest in South-Germany (Höglwald) receiving an annual N-deposition of 2.9 g m −2 . NO emissions close to the detection limit were observed from a pine forest in Finland where the N-deposition was 0.2 g N m −2 a −1 . No significant correlation between N 2 O emission and N-deposition was found. The highest average annual N 2 O emission (20 µg N 2 O-N m −2 h −1 ) was found in an oak forest in the Mátra mountains (Hungary) receiving an annual N-deposition of 1.6 g m −2 . N 2 O emission was significantly negatively correlated with the C/N ratio.The difference in N-oxide emissions from soils of coniferous and deciduous forests may partly be explained by differences in N-deposition rates and partly by differences in characteristics of the litter layer and soil. NO was mainlyCorrespondence to: K. Pilegaard (kim.pilegaard@risoe.dk) derived from nitrification whereas N 2 O was mainly derived from denitrification. In general, soil moisture is lower at coniferous sites (at least during spring time) and the litter layer of coniferous forests is thick and well aerated favouring nitrification and thus release of NO. Conversely, the higher rates of denitrification in deciduous forests due to a compact and moist litter layer lead to N 2 O production and NO consumption in the soil.The two factors soil moisture and soil temperature are often explaining most of the temporal variation within a site. When comparing annual emissions on a regional scale, however, factors such as nitrogen deposition and forest and soil type become much more important.
