Impact of uncoventional technologies of soil cultivation on soil quality
Suchá, Kateřina ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
Agricultural land is being handled by various tillage of soil which affects properties of soil. There are two types of tillage treatment. These are conventional (classic) tillage with plowing and minimization tillage (plowing is excluded). The aim of this particular work is to assess the quality of the soil near the village of Bohaté Málkovice, which is being (long-term) handled by minimization tillage. As indicators of soil quality, we used selected physical and physico-chemical characteristics, which are determined from analysis of disturbed and undisturbed soil samples from the top soil layer (0-10 cm) by standard methods in laboratory conditions. The theoretical part describes the basic physical properties of the soil and the ways of their determination. The practical part is devoted to the presentation of the examined locality and the results of selected physical and physico-chemical properties of the soil are presented and subsequently evaluated. In the conclusion, the impact of used tillage in Bohaté Málkovice on the selected soil properties is assessed.

Changes in physical properties of the subsurface soil layers depending on the technology tillage
Bažantová, Adéla ; Larišová, Lucie (referee) ; Kameníčková, Ivana (advisor)
For the correct course of soil processes, plant growth and development is necessary the tillage of soil. Usually we choose between two technologies, that those adjustments are cariied out by. Both are conventional tillage, which uses plowing and minimization tillage, wherein is excluded plowing. Objective of this work is to determine the impact of these tillage treatments on selected physical properties of soil, i. e reduced bulk density of the soil, porosity, momentary contents of water and air in the soil. Soil samples were collected by Kopecky rollers (V = 100 cm3) taken from depths of 0,1; 0,2 and 0,3 m that were used to evaluate. Two samples were collected each July. This period is referred as a critical due to higher soil compaction (movement of mechanization, root system of plants and rainfall totals). Experimental research was conducted in years 2008 – 2011 in the village Bohaté Málkovice.

Využití různých technologií zpracování půdy ke kukuřici v podmínkách zemědělského podniku
Daněk, Jan
The literature part of the bachelor thesis deals with soil characteristics, maize sowing and soil processing. In the soil processing chapter, the different soil processing technologies are divided and characterised. The bachelor thesis focuses on the comparison of four soil treatment methods - shallow loosening, deep loosening, medium loosening and plough-ing. A one-year semi-operational experiment was carried out on the land of Agrodružstvo Žimutice. The experiment was mainly focused on the comparison of yield from the differ-ent variants, but other parameters were also evaluated - number of plants per m2, grain moisture at harvest, protein and starch content, bulk density and HTZ. All data were ana-lysed from a one-year semi-operational experiment. The highest yields were obtained with shallow tillage and the lowest yields with deep tillage. However, the yields were not statistically conclusive. Statistical significance was observed for the qualitative parameters of protein content, bulk density and HTZ.

Vliv různých způsobů zpracování půdy na její zhutnění
Chlaň, Filip
The bachelor thesis investigates soil compaction and changes in soil physical properties in different tillage systems. The experiments were based on heavy soil in a potato production area. Three tillage methods were used, the first was ploughing, then shallow tillage and chiselling. For each variant, Kopecky physical cylinders were taken and the penetrometric resistance of the soil was measured on two dates, after tillage and after spring barley harvest. From the Kopecky physical rolls, the reduced bulk density, porosity, minimum air capacity and soil moisture content were determined. Soil resistivity in the soil profile was determined with a penetrometer. Spring barley was then sown in the experiments and its yield was measured to assess the effect of tillage and possible compaction on this parameter. The results show a positive effect of minimization technologies on compaction resistance, whereas tillage was more prone to compaction according to the results. In the first term of measurement, better values of physical properties were recorded for ploughing, but in the second term, ploughing deteriorated. The minimization technologies showed similar values in the first and second measurement. However, the results showed that neither variant showed significant soil compaction with deterioration of soil properties. Similarly, the yield was not different between the variants.

Vliv různého způsobu zpracování půdy na obsah vody v půdě
Mazel, Petr
The thesis deals with the effect of different tillage on the water content in the soil. The theoretical part is devoted to soil, soil properties, characteristics of soil tillage and the effects of soil tillage on soil properties. Monitoring of the effects of tillage on soil moisture was carried out in plot experiments at the Žabčice Field Experiment Station of the Mendel University in Brno. The experiment took place in 2022 and 3 tillage variants were monitored (traditional tillage, minimization tillage and no-tillage). For the assessment of soil moisture were determined: mass moisture, volume moisture, relative humidity and soil absorbency. Soil samples were taken on plots with winter wheat (Triticum aestivum L.) at three depths (0-10 cm, 10-20 cm, 20-30 cm). For mass moisture was statistically significant difference (p < 0.05) demonstrated between tillage variants, and the highest moisture was achieved with traditional tillage of 17.11%. For volume moisture were not found statistically significant differences (p < 0.05) between the tillage variants. For relative humidity were statistically significant differences (p < 0.05) achieved between treatment variants with the highest value in the no-till variant of 53.03%. A statistically significant difference (p < 0.05) was found for soil absorbency between traditional and minimization tillage, and the highest absorbency was achieved after traditional tillage of 38.75%.

Porovnání různých způsobů zakládání porostů kukuřice seté
Dubový, Miloslav
Maize is one of the most produced crops globally. It has many uses in livestock farming, food production, and industry. With the recent decline in livestock production, the amount of maize in crop rotation has been reduced. However, the production increased again with the arrival of electricity-generating biogas plants. Since most of the land is not covered when cultivating maize in rows, soil erosion occurs. Minimum tillage and soil conservation technologies are used to prevent this side effect, especially on sloping land. The thesis deals with these issues, collects information on various methods of maize cultivation, and compares these technologies in a semi-operational experiment, both from an economic and technical point of view.
