Vliv chemické meliorace na půdní prostředí v kořenové zóně smrku ztepilého v oblasti Nízkého Jeseníku
Hošek, Michal
The influence of applied fertilizers on the selected pedochemical characteristics in the root zone of Norway spruce (Picea Abies /L./ Karsten) were observed in the selected natural forest region (NFR 29). Two research areas were established, divided to single plots and they were consisted of young stand of Norway spruce. On each plot, the application of powdered fertilizer from the Silvamix, Silvamix R + stimulator a Silvamix A series, was used. The soil samples from the root zone of the spruce were collected regularly. The influence of the fertilizers on the pedochemical characteristics was monitored for two years. From the measurement results is observed, that applied fertilizers affect the soil environment and when properly applied, they can positively influence the pedochemical factors. The effect of the fertilizer is also limited by single ecological site conditions. The biggest influence was observed in the fertilizer Silvamix R + stimulator, which varies the most from the control plot.

Moderní prášková hnojiva s růstovými stimulátory a jejich využití při zalesňování v Krušných horách
Slivková, Tereza
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.

Porovnání účinků přípravků Silvamix Agluform a VERMAKTIV stimul při obnově lesa ve vrcholových partiích Králického Sněžníku
Kadlec, Jiří
The thesis engages in influence of Silvamix Agluform and Vermaktiv Stimul preparations on Norway spruce (Picea abies) young plantations nutrition on Kralický Sněžník area. The main goal of thesis is assessment of effect on applied preparations like treatment more rapid established plantation. On the research plots were applied to particular products and subsequently were studied their effect on health, annual increment and foliar concentration of basic nutrients. Based on mentioned analysis, it is possible say that the best results achieved fertilizer Silvamix Agluform, on research plots have also seen the positive effect of Silvamix R and Silvamix R + Stimul. The Vermaktiv Stimul failed to demonstrate the stimulation effect on Norway spruce young plantations.

Efekt aplikace minerálních hnojiv a organominerálního stimulačního přípravku na výživu, vývoj a odrůstání smrkových monokultur v PLO 29 - Nízký Jeseník
Hošek, Michal
In selected natural forest areas, was observed the effect of fertilizers on nutrition and re-growth of Norway spruce (Picea Abies). There were established two research areas with secured cultures of Norway spruce. The plots were divided into individual fertilizery parcels. Then on the individual variations were applied fertilizer powder series Silvamix (Silvamix R + stimulator Silvamix A) and organomineral product Vermaktiv stimulus. Influence of fertilizers was evaluated one year after the application. The samples were colected periodically (once year) and the morphological parameters (height,thickness) also. It was observed from the results that the application of fertilizers can affect nutrition and re-growth of Norway spruce cultures. However the effect of fertilizers varies depending on ecological conditions of the station.Top influencing fertilizers were Silvamix R + stimulator and Silvamix A.
