The main aim of this thesis is Evaluation of compost phytotoxicity produced in composting plant of Svitavy. Biodegradable waste as a whole is also mentioned. This work is divided into several parts. Theoretical part aims to describe basic terms regarding biodegradable waste, legislation and statistical data. Moreover you can find way of handling biodegradable waste there but main focus is on the process of composting. Practical part describes composting plant facility in the city of Svitavy and all of the laboratory procedures used to evaluate compost phytotoxicity of studied samples. Three main methods of evaluating compost phytotoxicity were used phytotoxicity test using set Phytotoxkit, flower pot test and test phytotoxicity by Plíva. All of those methods utilized seeds of the Sinapis alba L and Cannabis sativa L. Last part of this thesis contains test results and their evaluation.

Surface mining of coal in the country leaves a lot of damage. This type of mining is characterized by the creation of large external dumps. The dumps often contain substrates with toxic substances or substances which become toxic after reaction with air. These substrates are toxic to plants and edaphon. This work is intended to show what properties of substrates are important for phytotoxicity. The location of research was selected including 3 different kinds of substrates, terrain unevenness and a lagoon in the middle. Coordinate grid has been created on the selected location. At each point a test was conducted with plant Sinapis alba and biomass was extracted from a naturally growing vegetation. Further, at the points substrates were collected and values of pH, conductivity and arsenic were measured. Test with plant Sinapis alba was repeated in the laboratory conditions as well. On site GPS coordinates were measured for the mathematical model created in ArcGIS. Experiment has shown the importance of the type of substrate and the geologic description, and then the association between dejection, value of pH and conductivity. Conductivity and pH levels also correlate with the germination Sinapis alba and biomass of naturally growing vegetation.

The topic of this thesis is Composting of biodegradable waste in Prerov town. The literary part describes biodegradable waste, legislative regulations, statistic data, biodegradable waste management methods and composting process. The practical part describes biodegradable waste management methods in Prerov town. There is described and evaluated a process in composting plant in Prerov Zeravice. After that there is a questioner research how to be potentially use the compost from the composting plant Prerov Zeravice. The questioner research was focused on agriculture organizations which are closed to Prerov town. The closing part of this thesis describes fytotoxicity test results of compost collected samples. In the fytotoxicity test a plant Sinapis alba L. was used.

The diploma thesis “The assessment of the phytotoxicity of sludge from selected sewage treatment plants“ deals with the current situation of the sludge treatment and disposal and the assessment of phytotoxicity of sewage treatment sludge. The sewage treatment sludge comes into existence during the process of sewage treatment. Nowadays is sludge landfilling from the point of view of nature protection and according to the legislation on the last place in a way of handling. Additionally, the thesis pays attention to the legislation related to the sewage treatment sludge and also statistical data concerning the production and the way of handling of the sewage treatment sludge. The practical part of the diploma thesis is focused on the description of two sewage treatment plants, namely Třebíč and Náměšť nad Oslavou. Subsequently were made several laboratory experiments with the sewage treatment sludge samples from the mentioned sewage treatment plants. At the sewage treatment sludge samples were assessed the phytotoxicity level by the testing set Phytotoxkit. Specifically was determined an inhibitive/stimulative effect on the growth of the root. The testing plant was a white mustard (Sinapis alba L.).
