Využití kompostů, vermikompostů a jejich výluhů společně s bioefektory při pěstování rostlin. / Use of composts and vermicomposts and their extracts together with bioffectors for growing of plants.

Bouček, Jiří January 2016 (has links)
The aim of this project will be to determine the influence of conditions during composting and vermicomposting of biodegradable waste of organic matter on physical-chemical properties of compost and vermicompost extracts. From this point of view mainly the content of basic nutrients and humin substances will be monitored and also the possible content of risk elements. In the same purpose the presence of different types of microorganisms in these extracts will be investigated and the enzyme activity of microorganisms in their extracts will be also determined. The extracts will be simultaneously prepared under aerobic and unaerobic conditions in different portion among the organic matter and its leachate and each sample variants will be compared to above conditions. The real effect of extracts applied on grown plants or into a soil including the fungicide effect of sample extracts during pot experiments will be reported. The effect of extracts will be also compared with commercial bioeffectors.

Vplyv pridania zuhoľnatených rastlinných biomás na vermikompostovanie

Gundová, Zsuzsanna January 2014 (has links)
Diploma thesis presents the issue of the impact of the addition of charred plant biomass for vermicomposting. The theoretical section describes the definition of biochar, its production, and application benefits to the soil, and other purposes. In other section, devoted to vermicomposting, there is defined the methodology of domestic vermicomposting. The chapter which is devoted to the own experiment is based on the hypothesis that biochar slows down the process of vermicomposting, reduces odor and emissions produced during the process, and that the combination biochar with vermicompost would be a suitable alternative fertilizer. During the experiment, two bins for vermicomposting were used. Biodegradable waste and biochar were added to the first one, and biodegradable waste were added to the second one. The same type and amount of substrate were added to the bins, and they were placed under certain conditions. The difference was only in the addition of biochar. During the whole process, vermicomposting diversity and the resulting product were studied. Vermicompost was evaluated by the available methods.

Vliv vermikompostu na růst rostlin a rozvoj mykorhizní symbiózy

Prokopová, Ladislava January 2015 (has links)
The theoretical part is devoted to the production of vermi compost, earthworm breeding and arbuscular mycorrhizal symbiosis. The practical part of the procedure followed in establishing containter experimentwith lettuce (Lactuca sativa), further evaluation and processing of results in tables and graphs. The aim was to experimentally determine the effect on plant growth vermi compost. Furthermore, it aims to validate the influence of colonization root mycorrhizal fungi. Effect of vermi compost to an average dry weight of aboveground and underground materials was confirmed and significant difference was observed. Vermi compost had also an influence on the length outer root root hyphae per cm2 membrane filter. Impact on the percentage of root colonization was clearly confirmed. In addition, as of Symbivit mycorrhizal positive influence on above and below ground biomass and the length outside the root hyphae. Impact on the percentage of root colonization was not significantly manifested.

Porovnání a hodnocení zařízení pro vermikompostování a kompostování v pásových zakládkách

Hustý, Miroslav January 2017 (has links)
The current thesis focuses on comparison and evaluation of technical equipment for vermicomposting and composting in band piles. The technology of processing of biowaste and necessary technical equipment and machinery of composting plants are compared. The work is based on data obtained from field work, literature and internet sources. Two plants with different technologies of composting are assessed. I am considering the construction, technical equipment and machinery needed for daily operation in both plants. Also the final product - compost is explored in laboratory. The final results show that plants of similar size have similar requirements for technical equipment and machinery and their final product is equal in law requirement regarding dangerous substances.

Výluhy z vermikompostů produkovaných za odlišných podmínek / Extracts from vermicomposts produced under different conditions

Kahanec, Julius January 2016 (has links)
The main purpose of this study was to determine if aeration and extraction time influence on the properties of extracts produced under different conditions. The leachates for our experiment were obtained from five different kinds of vermicompost (from horse manure, digestate, marc, apple pomace and from kitchen waste). Has always been prepared 1kg of vermikompost and using special extraction equipment for leaching in 9 liters of water. Attempt always proceeded 48 hours and at predetermined intervals, were taken control samples. Every 1h, 6h, 12h, 24h and 48h. The leachates were prepared in two variants. The first variant was without aeration at a constant temperature 30 °C and stirring 750 rpm. The second variant was with aeration at a constant temperature 30 °C and stirring 750 rpm. In this work we are evaluated in terms of leachate contents of ammonium nitrogen(N-NH4+), nitrate nitrogen (NO3--N), total nitrogen, dissolved organic carbon (DOC). Analytical equipment placed on the apparatus measured the remaining variables evaluated in this work - pH, conductivity and dissolved oxygen. The leachates produced with aeration generally reached higher values than the leachates produced without aeration. This difference was only 6%. The highest increase during exgraction was the ammonium nitrogen in a variant with aeration. Other endpoints were higher by only a few percent . The extraction time effect on the properties of extracts was clear. The highest rates of increase was in the first 24 hours, when values were rising most. The remaining 24 hours have had such importance. Time certainly had a great influence on the properties of the extracts, but the last 24 hours of leaching characteristics has not changed significantly, so it is not necessary to infuse for 48 hours.

Pomocné látky ve vinohradnictví - přípravek Vitality komplex

Rozkydalová, Radka January 2019 (has links)
The aim of the thesis was to study and investigate written literary sources about aid substances used in viniculture. The substance named Vitality complex was then used in trial for experimental part. The trial was set in vineyard located in Slovacká wine-making area in village Karlín and was performer on varieties: Riesling Weiss, Pinot Gris and André. Substance Vitality complex was applied by spraying onto the leaves using concertation and time interval following the recommendations from substance producer. Substance application was performed from April till August. Control grape picking was done during August and September and quantity and quality changes against a check sample were observed. Focused parameters were weight of grapes and weight of bunch of grapes, sugar content, acid content, power of Hydrogen (pH) and yeast assimilable nitrogen. This gathered data were then processed and compared with existing trial results where different supporting substances were used.

Změna produkčních charakteristik modelových rostlin po aplikaci vermikompostu s přídavkem bakteriálního inokula

Malsová, Anna January 2019 (has links)
This diploma thesis deals with the change of production characteristics of model plants after application of vermicompost with addition of bacterial inoculum. In this work is elaborated a literature review focused on the process of vermicomposting, composting and stimulation of the root system of cultural crops using symbiotic or growth-promoting microorganisms. In addition, a practical experiment was carried out - an in-house vessel experiment with model plants was established, which was evaluated. The resulting data suggest that the most suitable variants in the formation of above-ground biomass were those containing vermicompost. The highest weight of aboveground biomass was achieved in vermicompost with the addition of Rizocore, where the production of aboveground biomass was increased 1.5 times compared to control soil.
