Effects of soil management on soil quality near Šardičky village
Schneiderová, Šárka ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
This diploma thesis is focused on influence of reduced tillage technology of soil processing on it´s near-surface soil layer (0 to 10 cm). The research was carried out on agricultural land near Šardičky village, where company ZEMO spol. s r.o. provides long-term use of reduced tillage technology. In 2016 the soil quality in this site was evaluated by using physical and hydrophysical parameters, results are presented in the previous bachelor thesis "Selected hydrophysical parameters as indicators of soil quality.". In diploma thesis in addition chemical and other hydrophysical properties have been evaluated to provide a comprehensive assessment of soil quality. In 2016, poppy seed was grown on this site and spring barley was grown in 2017 and 2018. Grab samples and intact soil cores were taken during the vegetation period of the crop. After three years of experimental research, in which I participated, it is possible to assess the development of individual parameters and the influence of reduced tillage technology on near-surface soil layer. The theoretical part of the diploma thesis deals with the description of the reduced tillage technology and problematics of the determination of soil parameters, which are used for evaluation of the quality of the near-surface layer. The practical part deals with evaluation of these parameters according to various authors and describes the development of soil quality during years 2016, 2017 and 2018.

Vliv plazmatem aktivované vody na vybrané půdní vlastnosti u různých půdních typů
Voldán, Fabián
The diploma thesis ,,The effect of the application of plasma-activated water on se-lected soil properties in different soil types” researched the effect of the application of plasmatic activated water (PAW) on six different location. This diploma thesis researched soil conductivity and soil reaction. The samples were taken from thirteen locations in autumn 2020. In the year 2021 was done container experiment with application PAW and distilled water. One of the samples was inspecting sample without application PAW and distilled water. This experiment was repeated in the year 2022. The PAW was made from distilled water in DBD system with liquid electrode. Based on the results it follows that the application of PAW is addicted on the soil properties. Although the PAW was applicated in the high dose no significant changes which should result in the end of the use of PAW in agriculture or in other environmental sector.

Hodnocení aberace půdy vybraných katastrů okresu Třebíč
Nováček, Miroslav
This bachelor thesis focuses on farmland aberration, which is the change in soil properties over time, this change can be positive or negative. To determine the form of aberration, the results of soil analysis were compared with the results of a Comprehensive soil survey from 1965, in the cadastral area of the municipalities of Hartvíkovice and Popůvky in the Třebíč district. The compared values include mainly soil exchange reaction, grain size and humus content. Various soil degradation processes, including water and wind erosion, acidification, loss of organic matter and compaction, cause the negative aberration. After analysis, the results showed that for all the probes examined, positive aberration occurred with an increase in pH and humus content. There was a change in the grain composition of the soils and some soil horizons were shortened.

Indicators of ecosystem recovery after heavy disturbances
Hermová, Markéta ; Frouz, Jan (advisor) ; Hardekopf, David (referee)
Minerals mining have huge impacts on the coutrryside and fundamentally change its character. The restoration of the habitats can be done basically in two ways. The mine can be either abandoned and left to natural succession or recultivated. In order to decide how to proceed on actual site, we have to carefully consider all the surroundings and set the objective we want to reach. Naturally, we are not able to monitor all the characteristics present in given locality and their changes. Therefore it is highly convenient to use a set of indicators, which can cover majority of these characteristics and will sensitively respond to development of the whole ecosystem. I decided to use three types of indicators in this study. These are physiochemical environment, ecosystem production and diversity. Through these indicators I have analysed the restoration possibilities of degraded ecosystems in localities used for coal mining in former times. I have chosen coal because it is an important commodity in Czech Republic.

Chemical Properties of Flue Gas Desulphurization Gypsums from Different Energy Sources
Kroulíková, S. ; Mercl, F. ; Száková, J. ; Perná, Ivana ; Tlustoš, P.
There were compared flue gas desulphurization gypsums (FGDGs) from four different power plants in the Czech Republic on chemical properties (pH, total content of nutrients and risk elements) and then was assessed their potential for utilization in agriculture as fertilizer without any risk to the environment. According to our results, the FGDGs represent an important possible source of sulphur (17.8 – 19.0 %) and calcium (23.0 – 30.2 %) for reduction of their deficit in the soil. However, contents of arsenic and of mercury in three of the tested FGDGs not fulfil the limit values for fertilizers. In the future, the remaining FGDG is thus necessary to evaluate for its fertilizing effects in model and field conditions.\n\n

Acidification of Czech soils and its threat
DAŇHELOVÁ, Jitka
This work focuses on the dangers of acidification of the soil in our conditional environment, and the related events that have a negative reflection on the entire ecosystem, including the socio-economic consequences for the entire community as well. It describes the causes of soil acidification, its primary markers, and the negative impact on the soil environment, plants, and edaphon. Soil reaction plays an important role, and bears evidence of the quality of the soil in a given location. The dangers the soil acidification introduces do not only affect the field of agriculture, but is significant from an ecological perspective, where we can assess the influence of acidification on the environment. An increase in soil acidity leads to leaching of nutrients from the soil, increased mobilisation of toxic substances, a disruption of natural microbiological processes in the soil, it enhances the effect of other degradational processes, and the loss of the natural processes of the soil is often irreversible. The effect of calcium on the soil and its role in plants' ability to absorb nutrients is also examined. The work also deals with how to neutralise acidic soil, in which the application of calcium on agricultural soil plays the most important role. The effect of calcium changes the characteristics of the soil, such as soil fertility, soil reaction, availability of nutrients, biological activity, and others. Since the 1980s, there has been a significant decrease in the use of calcium products. This study evaluated the results of agrochemical testing of agricultural soils for the past twenty years, in which the results show a clear, continuing decreasing trend in pH development. The conclusion focuses on an assessment of the information, an evaluation of influences, and recommendations for corrective and preventative measures.
