Design of Light Agricultural Tractor
Oulehla, Jakub ; Chorý, Tomáš (referee) ; Křenek, Ladislav (advisor)
The subject of this diploma is the design of a versatile light agricultural tractor. The design of the tractor will focus on timeless design. The proposed tractor will also differ from the current competition in the field of light agricultural tractors. The resulting tractor will also be usable outside agriculture, in horticulture or communal services.

Jaroslavice – place in the landscape
Mrlinová, Lucie ; Veselá, Markéta (referee) ; Foretník, Jan (advisor)
South Moravia has a good quality soil. Changing climatic conditions and an unhealthy human approach result in drought and soil erosion. Soil, like our nutritionist, is very rare. Therefore, in my work I deal with the proposal of a research institute for soil protection, which I place on the site of a former manor court in Jaroslavice. The Institute consists of three buildings that define a common yard. The location of the complex complies with the direct connection to the adjacent experimental field. Jaroslavice, as a municipality in the warmest and driest area in the Czech Republic, is ideal for research.

Fusion of Radar and Visual Data for Remote Sensing
Strych, Tomáš ; Beran, Vítězslav (referee) ; Kolář, Martin (advisor)
Cieľom práce je vygenerovať satelitný optický snímok v prípade jeho nedostupnosti. Takýto snímok je vygenerovaný z aktuálneho radarového snímku a za pomoci radarových a optických snímkov z minulosti. Zameranie práce cieli na poľnohospodárstvo, kde sa na analýzu dát používajú rôzne vegetačné indexy. Pre zjednodušenie problematiky je práca zameraná len na optický snímok zobrazujúci NDVI. Boli vytvorené 4 dátové sady, pre prvé tri ročné obdobia a~štvrtý, ktorý ich spája. Pre riešenie problému preloženia obrázku z jedného na druhý bol použitý model Pix2Pix-cGAN. Výsledky práce zobrazujú rozdiely pri použití dátových sád, rozličného množstva a~typu použitých snímkov, tak ako aj intervalu medzi snímkami. Daným výskumom bolo zistené, že sieť je schopná vytvárať reálne uveriteľné obrázky s validnými numerickými hodnotami, avšak má problém správne využiť informáciu o radarovej zmene, ktorá je dôležitá pre ohodnotenie vývoja rastlín práve v prípade nedostupnosti optického snímku. Táto práca a~jej výsledky sú jedinečné vďaka naprieč Európou geograficky rozmanitej dátovej sade a vďaka zameraniu na agrikultúru, a to bez ohľadu na typ plodín.

Nitrate removal from agricultural runoff
Schrimpelová, Kateřina ; Šálek,, JAN (referee) ; Drtil,, Miloslav (referee) ; Malá, Jitka (advisor)
The increasing concentration of nitrates in surface water and groundwater is becoming a global problem. The dissertation thesis is focused on the denitrifying bioreactors with organic fill material designed for the reduction of nitrate input from agricultural areas in the Czech Republic. A set of laboratory experiments was performed – static leaching tests and column tests, including chemical analyses of outflow water and ecotoxicological bioassays. Seven materials common in the Czech Republic, various process parameters, types and lengths of bioreactor shutdown in dry periods and the use of outflow water for irrigation were tested. The thesis deals with both denitrification efficiency and ways of reducing negative effects. An evaluation of the overall effect bioreactors is included along with a prediction regarding leaching over the following years.

Simple agrocontroller
Pelikán, Michal ; Friedl, Martin (referee) ; Steinbauer, Miloslav (advisor)
Simple agrocontroller is a realization of control computer of spray machine in agriculture technique. Introduction describes the types of individual sprayers and their main differences. Hydraulic scheme displays the layout of regulators, ventils, hosepipes etc. Chapter Requirements defines needed functions and variables. Next chapter explains the structure of the layout of agrocontroller´s individual parts. Also defines required functions and features of these parts with real circuits and components and methods of gaining required values. Practical part show how printed circuits boards look like and what are features and properities of agrocontroller.

Utilization of biomass energy
Horváth, Martin ; Bok, Jaromír (referee) ; Procházka, Zdeněk (advisor)
Restoring sources of a energy and their development brings questions how these can be these sources the best utilized. The main aim of my bachelor`s thesis is an acquainted with methods of biomass conversion to energetic potential and his advantage. Than is mentioned proper project of the biogas plant and calculation of produced electric energy quantity in select cogeneration unit base on data on specific excrements production bred pigs and biogas production from slurry. The result is a variant evaluation of economy of the biogas plant operation for agricultural enterprise according to number of bred pigs and possibility of electric energy utilization.
