“…Many specialists studied fertilization and liming as possible revitalization treatments in declining Norway spruce forest stands (Badalík, Řezáč 2001;Musil, Pavlíček 2002;Podrázský et al 2003;Schaaf, Hüttl 2006) or as measures to increase the volume increment (Derome et al 1986;Materna 2001). On the other hand, the complex analyses of aerial spraying and quality (variability) of aerial application of both fertilizer (using a crop duster) and dolomitic limestone (using a helicopter) have not been performed yet.…”

ABSTRACT:The paper evaluates the quality of revitalization treatments (fertilization and liming) carried out in selected areas within Forests of the Slovakia (state enterprise) during the year 2008. Revitalization treatments were carried out in declining Norway spruce forest stands in different site conditions. Full-scale aerial technology (helicopter and crop duster) was applied. The aim of the study was to find out the total amount and its variability of both fertilizers and dolomitic limestone after their application. The analyses revealed significant differences between the amount of fertilizer and dolomitic limestone which was applied to selected areas and the required amount (norm). As for fertilization, the largest difference was found in magnesium (Mg) on Šaling area (the amount of magnesium reached only 7% ± 0.5 of the norm) and in zinc (Zn) on Ľadová area (only 8% ± 1 of the norm). The required amount according to the norm was approximately met in boron (B) on Ľadová area (65% ± 10 of the norm). Yet, a significantly lower amount of fertilizers than the required one was revealed on all selected areas. After the application of dolomitic limestone to Liptovská Teplička area the significantly lower amount than the required one was found out (72% ± 12 of the norm). On the other hand, the significantly higher amount of dolomitic limestone than the required one was determined on Smolník area (143% ± 27 of the norm). Results also show the huge spatial variability of both fertilizers and dolomitic limestone on all selected areas (from 40% up to 100% between collecting places, and up to almost 170% between collectors within the collecting places). Such high variability of applied fertilizers and dolomitic limestone and the lower total amount than the required one will influence the effect of revitalization treatments.

“…In their studies, Vacek et al (2006) and Podrázský et al (2003b) report that optimization of Norway spruce nutrition as well as reduced defoliation and discoloration occurred after the application. The research area of Suchdol showed in the first growing season slight positive effect of calcareous dolomite on the foliar calcium and magnesium concentrations.…”

The aim of this study consisted in verifying the hypothesis whether the application of tableted fertilizers Silvamix® Forte, Silvamix® R, Stromfolixyl® and calcareous dolomite affected significantly the nutrition and growth of Norway spruce. In order to carry out research investigation, the experimental Suchdol locality has been selected as it represents large-scale reclaimed sites in the Krušné hory Mts. Ameliorating agents were applied using the initial spot fertilization of Norway spruce plantations. In the course of two years, activities as follows were carried out annually: (1) top shoots measurement, (2) sampling the latest needle year-class. The applied fertilizers impact on the concentrations of nutrients in needle dry matter was not significant with minor exception. Fertilizers Silvamix® Forte and Silvamix® R can be recommended to support seedlings growth in the area of interest since there had been positive effect on annual height increment found out. Calcareous dolomite showed the most favourable effect on the shoot biomass growth. Stromfolixyl® fertilizer had no effect on the annual increment; its impact on the nutrition can be characterized as insignificant since fertilized individuals showed lower phosphorus concentration in needle dry matter.

“…indicated decreasing availability not only of P but also of Mg, which in combination with soil acidification may be limiting factors for the forest nutrition in the future (Lomský et al 2012). On poor sites under former acidification stress the improved nutrient supply may act as a stimulus promoting growth and influencing the vitality and survival of especially young trees (Nilsen, Abrahamsen 2003;Podrázský et al 2003;Kupka 2005;Óskarsson et al 2006). Liming increasing the Ca and Mg supply can partly improve the accessibility of P (Formánek, Vránová 2002).…”

Sample trees were taken for analyses from an 18-years-old blue spruce stand growing in the summit part of the Jizerské hory Mts. (Czech Republic). The sample trees were measured and dry matter and nutrient contents were analysed in needles, branches, bark and stem wood. Based on the actual stand structure, correlations were calculated between the diameter, dry weight of components and nutrient reserves. Dry matter of the stand constituted 46% of the stand fresh weight. The highest amount of nutrients was accumulated in needles (from 42% in magnesium to 82% in phosphorus) and the lowest in the stem wood (from 2% in phosphorus to 15% in potassium). Regarding the character of the locality, the complete removal of aboveground biomass during tending operations represents a considerable loss of nutrients. If only the merchantable timber volume is processed, the loss of the elements from the ecosystem could be reduced to 8% (phosphorus) to 22% (calcium and potassium) of the total content of these elements in the aboveground biomass of removals.
