Sažetak
High amounts of atmospheric deposition of nitrogen (N) compounds are reported for large parts of Central and Southern Europe. The effect of increased N deposition on forest ecosystems has been debated. Under N-limitation, increased N deposition stimulates tree growth, but it can also affect an unbalance in the element ratio in plant tissues. Furthermore, it has been shown that excessive N deposition can increase tree sensitivity to pathogens, storms, and extreme weather conditions. We compared intensive monitoring data for two forest plots located in Croatia (Jastrebarski lugovi, 110) and Italy (Bosco Fontana, VEN2) at similar latitude, both dominated by pedunculate oak (Quercus robur L.) and with different levels of defoliation. The Italian plot is located in the Po plain, one of the areas in Europe rich in industries and agriculture. The Croatian plot, located in the Pokupsko basin floodplain, is affected by the same factors, but to a lesser degree. The aims of this study are the following: (1) to identify differences in N deposition and precipitation between the sites and across time ; (2) to evaluate differences in N uptake/release in the canopy and N ratio to other elements in foliage and soil ; (3) to evaluate if high amounts of N deposition can stimulate tree growth at different defoliation levels. Preliminary results show that the percentage of trees with defoliation larger than 25% is higher in plot VEN2, where N deposition is stronger, than in plot 110, but in the latter the percentage shows a marked increase. Although the C:N ratio in the soil is higher in plot VEN2 than in plot 110, comparison of elemental composition of foliar tissues show that the C:N ratio is similar in the two plots, but the N:P ratio is higher in plot VEN2.
