Utilization of recycled brick waste for growing the agricultural plants
Šmírová, Barbora ; Másilko, Jiří (referee) ; Opravil, Tomáš (advisor)
The master thesis follows up on previous bachelor thesis, which dealt with the sorption capacity of brick recyclate. Brick recyclate, as same as brick, excel with very high porosity. For this reason this work deals with possible implementation of plant growth aids (fertilizers) on the inside surface of such highly porous material This thesis studies possibilities of preparation of brick recyclate with the content of components supporting plant growth. It is a material, that is able to bind water in the soil and nourish cultivated plants at the same time. Aim of the work is to find out, what maximum amount of supporting substances, that later will be released back into surrounding enviroment (soil), is possible to incorporate into the brick recyclate. Such prepared recyclate was added in different amounts into predefined substrates, where plants were grown. Subsequently, the growth course, germination and yields of selected crops were monitored. It was verified that the material based on recycled brick enriched with nutrients improves the distribution of nutrients in the soil and positively affects the germination, growth and yields of tested crops.

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.

Recycling of phosphorus from waste water
Szotkowski, Matěj ; Bojanovský, Jiří (referee) ; Brummer, Vladimír (advisor)
The focus of this thesis is to create an overview of methods that are used to recycle phosphorus from waste products, primarily from wastewater. The first section of the thesis is dedicated to problems stemming from the limitations of phosphorus resources, their usage and legislative background of phosphorus recycling. Next the physicochemical and biological methods of phosphorus recycling from wastewater and products of its further processing in WWTP are addressed. This part of the thesis contains description of phosphorus recycling methods, their final products and implemented technologies. Brief review regarding the recycling of phosphorus from other waste products including the description of implemented methods follows. In the subsequent part the economic analysis of a chosen phosphorus recycling method (PASCH) is conducted. In the analysis the legislation, processing plant and individual expenditures connected with the method are described. Findings obtained and gathered during the process of the thesis creation are discussed and summarized in the conclusion.

Methodical practice of taking samples fertilizers, plants and soil for determination of risk elements in agro-ecosystems and other parameters of soil fertility: applied methodology with certification
Kunzová, Eva ; Menšík, Ladislav ; Hejcman, Michal ; Dostál, Jiří
The methodology is describing latest findings on methods of sampling of barnyard manure, organic and organomineral fertilizers, samplings of vegetable material and soil for determination of risk elements content. As a part of the methodology there is description of laboratory methods for determination of dry matter content, pH, content of essential nutrients and risk elements in samples (of farmyard manure, organic and organomineral fertilizers, vegetable material and soil). Methodology is describing methods of characterization of quality of soil organic matter (SOM) and most important limit valuables of risk elements in fertilisers, substrates and soils. The application of methodology will be in the corporation farming on arable soil, grassland, classical and also ecological agriculture. It will be used also by accredited laboratories, agricultural consultant and in advisory framework of Ministry of Agriculture of Czech Republic etc. Methodology can be used by civil servants, students and teachers in secondary schools and agricultural universities etc.

Determination of nitrate in root vegetables
Fiala, Petr ; Štursa, Václav (referee) ; Diviš, Pavel (advisor)
The Bachelor thesis deals with the study of nitrates occuring in different species of root vegetables. The aim is to compare the amount of nitrates in common type of vegetables to bio vegetables. The theoretical part of the Bachelor thesis is devoted to root vegetable in general and also to nitrates and their influence to human health and nature. Fertilizers and organic agriculture are also mentioned. The last chapter focuses on the analytical method. The measurrement is carried out by the ion chromatography and the outcome of nitrate concentrations in both types of vegetables is compared and discussed. The results point out higher concentration of nitrates in bio-quality vegetables.

Vliv organické výživy s využitím mořských řas na výnos brambor
Florianová, Viola
Theoretical part of this bachelor thesis summarizes basic facts about breeding and fertilization of potato plant. In practical part there is evaluated effect of several fertilizers made of seaweed (AlgaSoil, Alga 300, SoftGuard, CaBoron, ProBoron, Rootmost) on yield of two varieties of potato with different length of growing season Arlet and Dicolora. Small-plot field trial was founded in April 2015 at experimental field station of Mendel University in Žabčice near Brno. Achieved results were affected by unfavorable weather, especially by drought at the beginning of tuberisation. There were not noticed any statistically significant influences of yield of any trial variant. There was small increase in yield (4 %) in case of Dicolora variety fertilized by AlgaSoil. So the achieved results have to be proved in coming years.
