Vliv různých způsobů aplikace kompostu na mikrobiální aktivity a růst rostlin
Přibylová, Eva
Submitted diploma thesis entitled Effect of different methods of compost application on microbial activity and plant growth with investigation of the effect of certified Černý drak compost on the growth of 12 model lettuce plants. The introductiory part of the thesis is focused on basic knowledge about soil and compost, where the issue of compost application and the presence of edafon, which has an irreplaceable function in the soil environment, is described in more detail. Furthermore, the legal framework in the field of model plants planted in nutrient-poor soil in combination with certified Černý drak compost, which was collected at a compost plant in Brno, and the development of plants planted only soil that in poor in the important content of substances needed for plant growth. In container trials, compost was applied to the soil surface and into the soil body. The aim of this experiment was to clarify and find a suitable and appropriate method of compost application in plant cultivation. After compensating for the time needed to grow the model plants, the contend of leached nitrate nitrogen, ammonia nitrogen and phosphorus was determined in the laboratry. The amount of aboveground biomass grown was also evaluated. However, the dosage of compost depends on the cultivated crop, the given soil and the time of application.

Fieldwork in soil biology
Dufek, Dominik ; Mourek, Jan (advisor) ; Blažová, Kateřina (referee)
This thesis didactically processes three proposals of fieldwork for intermediate school pupils and students of lower grades of grammar schools. Two of the described sites for field education are located directly in the capital city of Prague (Prokopské valley, Meanders of Botič) and the third locality lies 30 km south of Prague (Medník). All field exercises are focused on soil, soil biology and ecology of selected localities. During the fieldwork, students apply active learning and record their results in worksheets. The first half of the thesis is a literary review describing the characteristics of the selected sites, the soil and soil organisms and selected methods of study of soil ecosystems. The last part of the literary review deals with general characteristics of field training as an organizational teaching form, its aims, methods and organization. The actual output of the whole work is the proposal of three fieldworks and methodological materials for teachers. Individual tasks in the worksheets are analysed from the didactical point of view. Two of the fieldworks were tested in school practice by the author of the thesis. The course of the two fieldworks commented and the results of the students' works are evaluated. The annex of the theses contains worksheets for students, their correct...

Interactions of fire with humus forms and edaphon
Martinovská, Aneta ; Frouz, Jan (advisor) ; Vindušková, Olga (referee)
The aim of this bachelor thesis is to examine the question if there is any connection between the rate of decomposition of litter, removal of litter from the soil surface by bioturbation and the frequency and intensity of wildfires. The work describes in detail the mechanism of fire, factors influencing the frequency and intensity of wildfires and their ecological impacts. It pays particular attention to the role of fuel availability for the fire. It describes the relationship between the quality of fuel, its quantity and the rate of its accumulation on soil surface and the frequency and intensity of wildfires. In particular, study brings forvard an idea that the accumulation of fuel on the soil surface in the form of more or less decomposed litter. The work points out that the amount of this fuel depends on the quality of the litter, but its production is based on the rate at which the litter (fuel) decomposes on the soil surface and how fast it is possibly incorporated into the soil by bioturbation of soil organisms. The work also pays attention to factors influencing the intensity of bioturbation and the rate of decomposition, presents the factors influencing the formation of overlying forms of humus. The work points out the possible dependence between these forms of humus and the frequency of...

Srovnání vlivu biologických odpadů rozdílné kvality na biologickou aktivitu půdy
Klásková, Veronika
This master thesis analyses the topic of soil biological activity after the addition of biodegradable waste of different quality (straw, grass, compost). A container experiment with a goal to determine the influence of fresh organic matter and stabilized organic matter on soil biological activity is a substance of this thesis. Soil biological activity was interpreted by soil gas production, namely CO2 and N2O, also by determining the number of microorganisms of individual physiological groups, by determining the cellulite organism activity and by assessing the growth of the indicator plant biomass. It was discovered that a material containing less degradable substances and a broad C/N ration (straw) can cause the depression of plant growth compared to application of stabilized organic matter (compost). However, if the applied fresh organic matter has a suitable composition and an optimal C/N ratio, it can be incorporated into the soil without prior stabilization, for example by composting, and it still may have a positive impact on growth of biological activity of the soil biota and it may positively affect the plant growth at the same time.

Effect of agronomic and nutritional measures on soil biological activity
KINCL, Petr
This bachelor thesis is a literature review, examinig the effect of agricultural and nutritional measures on soil biological activity. Bachelor thesis is systematically divided into several parts. At the beginning of the thesis are included important dates regarding soil organic matter and edaphon. Another part of the work has been to study effects of fertilization and liming on soil biological activity. Furthermore, there are studies on the impact of agro-technical measures and the impact of the application of pesticides. The paper also lists methods of research soil biological activity.
