This study estimates effects of hydrogel Stockosorb and slow-release fertilizer Silvamix on survival, damage, aboveground and root growth, and foliar nutrients concentration of bareroot and containerized Norway spruce (spruce) and European beech (beech) seedlings five years after planting on windthrow area in the Javorie Mts., Central Slovakia. The average survival rate of all seedlings was 74% and 54% one and five years after planting, respectively. Spruce survived better, but was damaged by game more and by drying leading shoot in a similar extent, when compared to beech. Within tree species, bareroot and containerized seedlings showed a comparable survival and growth. Silvamix decreased survival of spruce seedlings, and on the contrary, increased foliar concentration of some macronutrients in all seedlings, and temporarily the aboveground growth of bareroot seedlings; however, a significant effect of the additives neither on the aboveground growth nor on root dry weight, short root frequency and relative abundance of ectomycorrhizal roots was found five years after planting. The results suggest a relatively low survival rate of seedlings, the most probably due to a precipitation deficiency in the first growing season after planting and a certain but inconsistent effects of the additives tested on outplanting seedling performance depending on tree species and planting stocktype used.
