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.

The effects of different agro-technologies on the soil physical quality in selected localities in the South Moravian Region
Bažantová, Adéla ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
Farmland is being handled by various the tillage of soil especially for the correct course of soil processes, plant growth and development and of course profit. There are two types of the tillage of soil are their conventional (classical) which involves plowing and minimization tillage, where is excluded plowing. The last few decades, the development the tillage of soil focuses on minimization tillage. This includes loosing up small depth, soil conservation tillage and direct seeding. This thesis is aimed at impact of minimization tillage on selected physical and hydraulic properties of the soil. Sampling undisturbed soil samples was performed on the experimental plot Kozlany by Kopecky rollers (V = 100 cm3) from depth of 0 - 10 cm, during the year 2016. On this plot was used minimization tillage in the form loosing up small depth and direct seeding.

Assessment health/quality of the soil near the village Bohaté Málkovice
Suchá, Kateřina ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
Diploma thesis evaluates quality and healthiness of the soil health located close to Bohate Malkovice focusing on changes in both physical and chemical characteristics of the soil in time. The theoretical part describes physical, chemical, and biological parameters of the soil. Selected physical parameters are structure, texture, determination of measured weight, bulk density of the soil, porosity, actual volumetric water content of the soil, aeration, saturated and unsaturated hydraulic conductivity, infiltration, and colour. Chosen chemical parameters are pH, carbonates, soil electrical conductivity, and humus content. Picked biological parameters are microbial biomass, respiration, nitrogen content, and weed infestation. The practical part analyses selected indicators of quality of the soil from the location of the experiment close to Bohate Malkovice. The area under evaluation has been treated using reduced tillage for long term. The practical part is based on the laboratory examination of disturbed and undisturbed soil samples taken between years 2016 and 2018. Based on outcome results we can evaluate the quality of the soil considering plants growth, development, and soil fertility.

Influence of technology of basic soil processing on chosen specifications in the process of growing flint maize (Zea mays L.)
ŠIMEK, Roman
The diploma thesis is divided in two elementary parts. Current state and factors influencing soil fertility and its degradation are described in the literary part. An experiment, focused on comparison of two systems of starting the cover considering the period (spring, autumn) of realization of basic soil processing, is described in the practical part based on the methods. The influence of used technology of soil processing on its compaction was evaluated based on gauging the penetrometric resistance and on the evaluation of taken unimpaired soil samples. The values from the penetrometric gauging show that higher values were recorded at autumn dung ploughing in, compared to spring period. Higher values of the penetrometric resistance were gauged at headlands too. The difference in rail lines compaction compared to the field is dependent on the number of taken measures during the plant vegetation period and the measuring showed the compaction of lower soil layers. The values calculated from taken unimpaired soil samples show that the values of reduced mass per volume confirm the results of the penetrometric gauging. The values of maximum capillary water capacity characterize the soil at chosen stands as ?moisture-holding? and higher values were found out when using minimization technologies of soil processing. When comparing the period of soil processing, it was further established, that higher yield was when using the autumn dung ploughing and at the land with the autumn ploughing was also measured higher growth and weight of monitored corn, than at a land with work technologies done in the spring

Effect of different soil preparation on yield parameters of winter oilseed rape
TOMÁŠEK, Václav
This thesis deals with the issue of growing oilseed rape (Brassica napus L.) with using various technology of tillage. It is divided into two main parts. The first part includes literary overview witch deals with basic information about oilseed rape ant than with overview about technology of tillage. The main part of thesis is evaluation result of two years small-plot experiment from 2017/2018 and 2018/2019. This experiment was founded on the lands of Agricultural Farm VETO s. r. o. in the village Veselíčko near the city Písek. To the experiment was integrate four varieties. It was Mazari CS, Atora, PT234 and PX113. Each variety was sown in three kinf od variants of tillage. Variant with shallow tilage, variant with plowing and variant with deep tillage. All sown variant were repeated in four times. In the experiment was monitored influence of tillage to rapeseed yield, and also some yield elements like weight of thousand seeds, percentage of oil, number of fplants per square meter and number of pods per plant and root neck thickness. Higher yields were achived in 2018 when the average yield of all lands was 5,63 t/ha which in 2019 dropped to 3,80 t/ha. Influence of tillage on seed yield was worse in 2019 because this year had less precipitation. In this year was the best option with deep tillage. In conclusion, we can say deep tillage has positive effect, especially in drier years.
