The subject of this diploma thesis is a semi-operational research project, which was established with the aim to find out the usability of innovated fertilizers and stimulants. The survey was focused on the growth and development of spruce cultures. This diploma thesis builds on my bachelor thesis and its purpose is to extend the data for two more years of measurement and, above all, to complete a research project on selected pedochemical characteristics. Find out what impact the soil has on each of the Silvamix® tested fertilizers. Variants Agluform® 90S, Silvamix®R30, Silvamix®R30S, Silvamix®R50, Vermaktiv and calcium dolomite were used. Each year samples of the needles were taken and the total elevation, the diameter of the crown and the health status of the spruce culture were measured. For the last two years of observation, the soil samples were taken under the crown of spruce crown. After analysis of the soil samples and their evaluation, it was found that the application of fertilizers has a significant effect on height gain, health status, but also on the soil environment. A deficiency of potassium and magnesium was found in the research site. These deficiencies were the best compared by the Agluform® 90S fertilizer application which was the most successful of all the variants.
