Initial Fertilization Impact on Norway Spruce Nutrition and Growth in the Krušné Hory Mts.

Abstract

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.

“…The overall large-scale clear-felling of these stands allowed forest sites to be prepared using heavy machinery. The top soil horizons were considered heavily acidified and toxic, therefore, in the 1970s-80s they were raked in line windrows using dozer technologies (Podrázský et al 2010;Pecháček et al 2017). These measures were to facilitate and accelerate the regeneration of forest ecosystems.…”
