Possibility of utilization of solid waste from spent coffee grounds rafination for agricultural purposes
Slavíková, Zuzana ; Vespalcová, Milena (referee) ; Pořízka, Jaromír (advisor)
The main focus of this diploma thesis is the utilization of spent coffee ground (SCG) and its biorefinery products in agriculture primarly as a prospective organic fertilizer. The study verifies an influence of the addition of native SCG as well as its acid hydrolysed, defatted and oxidized forms to experimental clay soil on chemical and physical properties (ph, conductivity and mineral content). Growing experiments were realized by using Lactuca sativa to detect positive or negative effects on growth. Samples of basic soil and soil with the addition of commercial NPK fertilizer served as a reference to measuring data. Measurements showed that addition of SCG and products of its biorefinery to the soil caused a decrease of pH and an increase of conductivity of soil samples. Significant increase of extractable calcium, magnesium, manganese and moderate increase of potassium content was detected. 2 % addition of SCG to soil had no impact on plants growth. The number and visual appearance of lettuces were comparable with plants in basic soil. No seed on acid hydrolysed samples germinated, which was caused by an increase of conductivity and sulphate content in these samples. In defatted and oxidized samples the early germination and the highest number of lettuces was observed. The low content of phosphorus in all soil samples had a great impact on growth rate and visual appearance of cultivated lettuces. In comparison with soil with NPK addition, lettuces in samples with SCG and its form had a pink-grey colour and lower growth.
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.
A Donkey's Worth in South Africa: Domestic Laborer or Export Product; Socioeconomic impacts of China's skin trade on South African donkey owners

Kristen Binda A Donkey's Worth in South Africa: Domestic Laborer or Export Product; Socioeconomic impacts of China's skin trade on South African donkey owners Master Thesis Prague 2019 Abstract Within South Africa, rural communities use working animals instead of, or combined with mechanization for farming and chores. Development progress may have evaded these areas yet impacts them through globalization and China's expanded market power. The burgeoning market for ejiao, a popular Traditional Chinese Medicine made from boiling donkey hides is a growing issue. Wealthier Chinese consumers, a stalled South African rural population who missed development's benefits plus increasing economic and political engagements between the two countries allows a monopolized, and often exploitative market for donkeys. Politicians are eager to partner with Chinese ejiao retailers despite resulting decimation of donkey populations in some areas of Africa and destruction of livelihoods. I evaluate the value of donkeys as domestic laborers within South Africa along with how China's rapidly expanding market for ejiao and simultaneous consumption of donkeys has affected South Africa to answer in which context donkeys are more valuable. Interview responses and cost-benefit analyses are used to answer the research question and...

Towards the understanding of agricultural intensification impacts on farmland birds: the effects of changes in invertebrate food supply
Hološková, Adriana ; Reif, Jiří (advisor) ; Lučan, Radek (referee)
Populations of insectivorous farmland birds recently underwent dramatic declines. Agricultural intensification is the main cause of these population changes, but involves numerous different mechanisms. Changes in food supply are thought to be one of the key factors. Homogenization of diet supplied to insectivorous chicks reduces their growth rate resulting in their smaller size as adults; decreased abundance of prey affects both survival and fitness of chicks and the overall breeding success. The accessibility of food is one of the most important factors limiting the use of food-rich habitats. However, the impact of all these factors on population trends has been shown in a single species - grey partridge. While the effect of changes in food supply on the breeding success has been confirmed in many other species, there is a lack of information on subsequent links to the survival of fledglings and the major causes of mortality outside the breeding period remain unclear. In general, there is insufficient information on population consequences of the changes in food supply for farmland birds, particularly in Central and Eastern Europe - the region with different characteristics from those we find in regions in which most of the findings were collected. Without this information, it is difficult to...
The influence of agricultural activities on the stream water quality in natural reservation
The aim of this thesis is to evaluate the impact of agricultural activity on hydrochemical parameters of surface waters in connection with the occurence of specially protected species within the surface waters of a monitored area. A model was chosen for the evaluation of the situation - Bedřichovský potok, which is located in Novohradské hory. The river consists of lower and upper sub-waters. Forest management is applied within upper sub-basin, while agricultural management on arable land, meadows and pastures is used in the lower sub-basin. The monitored parameters were indicators of eutrophication of surface waters: Nitrate nitrogen (N-NO3-), Phosphate phosphorus (P-PO43-), and conductivity of undissolved material (NL105). The results showed that the agriculture management (especially on arable land) burdens the soil with nutrients and consequently erosion enters the substances, bringing them to the surface and ground water as a result. There was an increase of substances in the water after rain.
Finanční podpory hospodaření v zemědělském družstvu
The aim of this thesis was to evaluate the impact of financial support on farming in a chosen agricultural cooperative. In the theoretical part, the overall state of agriculture in the conditions of the Czech Republic, the current situation on the market with milk, beef and pork and the situation on the market with plant commodities were assessed.
Využití půdních rotačních fréz s horizontální osou rotace v zemědělství a lesnictví
The aim of the work was to verify the performance and design working quality performance of rotary milling machines with horizontal axis of rotation in artificial forest regeneration, support of natural forest regeneration in selected forest stands and in agriculture with different soil and terrain conditions. The measurement was carried out on four different carrier cutters, each machine carrying a different soil milling machine. Measurements took place in various environments as well as soil types, crops or quality requirements for the work performed. In this work are compared performance of given carriers, in terms of aggregation with individual models of milling machines. The tables show the most important parameters such as average fuel consumption, average area efficiency and fuel consumption to area efficiency. Furthermore, there is an evaluation of the quality of the work done.
Zhodnocení vybrané "správné zemědělské praxe" ve vybraném provozu s chovem skotu
This thesis deals with the topic of airpollutin caused by the greenhouse gases and ammonia which rises by cash breeding of dairy cows. Worldwide agriculture is considered as one of the biggest producer of ammonia. The thesis describes the environment and its components, law and legislation connected with this topic. The second part of the thesis deals with the measured and evaluated gases. The measurement took place at a collective farm in Skalka (farm Lipí), where dairy cows are bred. Both - the main measuring device and the distributor of consumption spots were supplied by the company INNOVA. Last part of the thesis mentions the ways how to reduce the stable gases production.
