Moderní prášková hnojiva s růstovými stimulátory a jejich využití při zalesňování v Krušných horách

This diploma thesis deals with the use of modern powder fertilizers with growth stimulators, which were used for afforestation of hollow Norway spruce (Picea abies / L./Karst.) after bulldozer soil preparation in the Ore Mountains at LS Klášterec nad Ohří. On these scarified areas of the 7th forest vegetation stage two research areas of Bojiště and Kiosek were established. The battlefield area Bojiště was divided into 6 plots, one of which served only as a check. On these parcels were distinguished Norway spruce (Picea abies / L./Karst.) specimens from growing trees (A) and seedlings (B). Norway spruce seedlings were fertilized with fertilizers series Silvamix® (Sivamix® SR50 + S2, Silvamix® SR30 + S2 and Agluform 90S + S2) and organomineral fertilizers Vermaktiv Stimul and Fungil. Samples of the last year of needles were taken once per year, as well as samples of the soil environment. Support of nutrients were extended and growth spruce cultivation especially by using fertiliziers series Silvamix®. Individual fertilizers were contributed to the promotion of the different nutrients, of course in relation to the composition of fertilizers. Further these fertilizers contributed to improving the vitality of individuals Norway spruce (Picea abies / L./Karst.). The area of the Kiosek was treated with the new fertilizer UNICON. On this area carried two years of research for the sampling of soil samples and the last year needles of Norway spruce (Picea abies / L./Karst.). Against a control variant UNICON has demonstrated the benefits of optimizing the soil enviroment of sprececulture. The overall effect of this fertilizer contributed growth of individuals on the surface and the overall balancing takings nutrients
