The main aim of this work was to learn about the health condition (foliage and yellowing) the structure and the growth of the spruce forest stands on two research areas at Stožec in the Šumava Mts., one of which area is fertilized by the product SILVAMIX MG and the second area is checking. Yellowing and defoliation of spruce forests in Šumava due to a lack of magnesium were repeatedly noticed in the eighties of the twentieth century. There was an experiment focused on the research reaction of spruce forest application of magnesium fertilizer (SILVAMIX MG NPK) in 1998. Fertilizer was applied manually in the spring of 2000 in the spruce-beech and spruce forest vegetative stage at a dose of 96,5 kg Mg/ha. On the fertilized areas was a significant improvement in the health condition of forest and also a reduction of yellowing. In 2005, yellowing symptoms of Norway spruce (Picea abys) almost disappeared. There is an every year yellowing and defoliation stands on the unfertilized control areas except the year 2006. There was a slight improvement in the health condition of stands in this year. We can say that the application of appropriate fertilizer leads to a significant improvement in the health condition of stands and it helps to their overall stability.
