nr 1

This work evaluates effects of tablet fertilizers Silvamix, Silvamix Mg and Silvagen on height and diameter growth of a young plantation of Norway spruce [Picea abies (L.) Karst.] and European larch (Larix decidua Mill.) after the third year of fertilizer application. The experiment was conducted on one experimental plot in the Low Tatra Mountains. The fertilizers were applied at a rate five tablets (50 g) per each tree, considering not treated trees as the control. The tablets were laid on the ground and thoroughly trodden into soil. ANOVA analysis did not reveal any significant effects of fertilizers on height and diameter growth of Norway spruce trees. The use of Silvagen resulted in significant effects on height growth of larch trees.
