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.
