Integrovaná ochrana rostlin v akvaponických systémech
URBÁSEK, Jan
The aim of this bachelor thesis was to develop a literature search focused on the issue of integrated pest management (IPM) in aquaponics. Due to the fact that the literature focused on IPM in aquaponics is very limited, the work is based primarily on information about plant protection used in greenhouses or hydroponics. Individual methods of plant protection were evaluated based on their applicability in various types of aquaponic systems. The evaluation also considered their real usage in commercial aquaponic farming. Prevention is proving to be the most effective. By following strict preventive measures, more significant problems can be prevented. Subsequent resolution of the problems can be quite complicated and can cause irreversible economic losses on plant products. Chemical protection is now commonly used in plant protection in greenhouses and hydroponics. However, the application of chemical pesticides in aquaponics is highly problematic due to their possible toxicity to aquatic organisms. Due to the limited possibilities of using traditional chemical pesticides, it is therefore necessary to look for other alternatives. Natural products based on plant extracts could become one of these alternatives. There is a large number of plants that have pesticidal effect, but the possibility of their application is without further research very limited, as most products of plant origin have not been tested for their toxicity to aquatic organisms. In this work has been created an overview of plant products available on the market that could be used against problematic pests and diseases. Also based on literature sources there has been created a list of plants that can be recommended for future research into usability and inclusion in the IPM system of large aquaponic farms.

Production and use of specialized substrates and organic fertilizers in agriculture: Methodology for practice
Šimon, Tomáš ; Usťak, Sergej ; Váňa, Vojtěch
The aim of the methodology is to provide to farmers, agricultural advisors, gardeners, producers and users of organic fertilizers and cultivation substrates, research workers and agricultural educators and all other interested parties, the basic information on the possibilities to use specialized substrates and organic fertilizers in agriculture. Its application in practice can ensure environmentally acceptable and economically efficient fertilization of agricultural crops. In the introduction, the methodology provides a basic overview of literary information about the concerned issue. Furthermore, the methodology describes the results obtained during the research project, which can be used in practice and provides agrochemical, agronomic and economic assessment. Part of the methodology is the assessment of agrochemical efficiency of fertilizer application at the cultivation of selected agricultural crops. There are described application methods and effects on soil and plants. Finally, it provides a summary of the results achieved and general recommendations for practice.
