Zpracování odpadní biomasy ze zahrady na domácím kompostišti
Šmarda, Zbyněk
Bachelor thesis with title "Process of trash biomass from garden on homemade compost" it is focused on problematic of homemade composting of biological decomposable waste from garden to created compost. In work there are described the individual proceses which are in progress durning composting. In practise it means cultivating and composting of mow biomass from the marked place and rakeing fallen leaves from fruit trees or bushes. Cuting of grass was beeing processed every month in vegetation period from the end of April to start of October and rakeing of leaves in November. For whole time of experiment metering of rainfall and size characterization of composted material was in progress, especially weight of waste biomass and also size change of composted material in compost place. Mettering results are filled in work.

Změna množství a kvality humusových látek u kambizemí po aplikaci kompostu
Balšánová, Nikola
The aim of bachelor thesis Effects of compost application on humic substances content and quality in Cambisols is to evaluate the effect of compost application on basic soil properties of selected subtypes of Cambisols. Cambisols were under different land use --Haplic Cambisol (Malonty, conventional tillage), Pseudogleyic Cambisol (Desky, minimum tillage) and Haplic Cambisol (Rapotín, permanent grassland). Results showed that compost application in conventional tillage system affected total organic carbon content, soil reaction and content of potassium in soil. Compost application in minimum tillage system affected total organic carbon content, soil reaction, water extractable carbon content and content of magnesium, calcium and phosphorus. Compost application in permanent grassland affected total organic carbon content, humic substances content, water extractable carbon content and basal soil respiration.

Vliv aplikace kompostu na množství a kvalitu půdních humusových látek
Hlaváčová, Marcela
Bachelor thesis is focused on assessment of humic substances content and quality under compost application. Long-term field experiments were established on Haplic Chernozem (Praha). We evaluated total organic carbon content, humic substances sum, humic and fulvic acids content, ratio HA/Fa, humification degree, nutrients content and absorbance of humic substances in UV-VIS spectral range. One way ANOVA -- analysis was used for statistical assessment of received data. Positive effect of compost on humic substances content and quality and on nutrients content was confirmed.

Porovnání vlivu aplikace biologického odpadu ze zpracování Jatropha curcas L. a kompostu na vybrané půdní ukazatele a pěstovanou rostlinu
Foltýnová, Anna
This Master's thesis is focused on problems of modern agriculture. Current agriculture is facing many problems that already exceed the production area. Among these belong soil degradation caused by inappropriate agricultural practices, erosion phenomena, etc. Both developed and developing countries have experienced these problems. This soil degradation is mainly caused due to lack of soil organic matter content. Current agriculture therefore faces the issue of how to solve this problem. A simple solution is based on increasing the content of the soil organic matter in arable land. In the first part, this thesis describes various problems of modern agriculture and also suggests possible solutions. Regarding to content of soil organic matter, the thesis proposes solutions in the form of compost application into the soil. Besides compost, thesis presents an alternative organic fertilizer Jatropha seed cake. Jatropha seed cake is produced as waste after oil extraction from seeds of Jatropha curcas L. In the first part both of these substrates are further described, along with characterization of Jatropha curcas L. The aim of this thesis was to compare the fertilizing effects of Jatropha seed cake with compost. For this purpose, a pot experiment was conducted under controlled laboratory conditions. Application effect of Jatropha seed cake and compost on soil and plants was monitored at selected soil indicators. The results describe the impact of Jatropha seed cake and compost application on production of plant biomass, soil hydrophobicity rate, mineral nitrogen mobility and soil microbial activity.

Možnosti využití kompostu při rekultivacích ploch kontaminovanými těžkými kovy
Kubná, Daniela
This diploma thesis deals with the effect of compost on heavy metal (Cd, Pb, Zn) contaminated soil. There are theoretically discussed contaminations, their sources and their impact as well as remediation possibilities. Work validates the assumption that compost has a positive effect on mobility reduction of heavy metals and their bioavailability. Verification is performed by the pot experiment, where the indicator plant lettuce (Lactuca sativa L.) has been grown on differently contaminated soils. When the experiment was finished, the lettuce biomass and soils were analysed. Detected concentrations of heavy metals have confirmed a positive effect on Cd and Pb immobilization. The immobilization of zinc was not affected by compost.

Analýza biodegradability plastových materiálů v laboratorních a reálných podmínkách kompostování
Zloch, Jan
This thesis is focused on biodegradable or compostable plastics. Focuses on their pro-perties and uses. The work also clarifies the concept of biodegradable and compostable plastic. The work also describes the process of composting and concepts associated with it. Finally, there are several chapters devoted to the normative environment that relates to biodegradable plastics in the thesis. There are connected researches concerning the verification of the degree of degra-dation of plastics known as compostable, biodegradable and 100% compostable, in the last few chapters. There were conducted simultaneously two experiments of disintegration selected samples of biodegradable plastics. The tests of disintegration in the laboratory and in real conditions of composting were founded in March 2014 for a period of three months. There was founded a phytotoxicity test after the expiry of the time allotted in the laboratory. In a real conditions the study time was increased to 12 months. After evaluating and comparing the results of both tests disintegration may be allowed the use of biodegradable plastics in composting under controlled condi-tions. Conversely, in real conditions of home composting these plastics can not be re-commended, does not decompose.
