The impact of agro-technology on the physical and hydraulic properties of the soil
Vláčilíková, Michaela ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
The bachelor thesis deals with the impact of agrotechnics on the physical and hydraulic properties of the soil. At the beginning of the work a literary research was elaborated on the above mentioned problems in the final part an evaluation of the physical and hydraulic characteristics of soil, which are used as indicators of soil quality. Experimental research was carried out in 2017 near the village Bohaté Málkovice, the soil on one area was processed by minimization technology and on the other parcel (with mild erosion) direct sowing was applied to the soil. The crop was sunflower.

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.

Determination of hydraulic characteristics of soil in a selected area
Salač, Jan ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
The diploma thesis is focused on issues of measurement and evaluation of hydraulic characteristics of soil. In the literary research, the definitions of hydraulic conductivity and retention curve of soil moisture, their measurements in laboratory and field conditions and the prediction of these characteristics by using of pedotransfer functions. In the practical part of the diploma thesis, an evaluation of the hydraulic conductivity of soil from the experimental areas near the village Bohaté Málkovice. Two-cylindrical and mini-disc infiltration meters were used for field measurements, and a constant-gradient permeameter was used in the laboratory. Physical and empirical equations were used to evaluate the hydraulic conductivity. The results were processed numerically, tabulated and then compared.

Selected hydropedological parameters as indicators of soil quality
Schneiderová, Šárka ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
When it comes to agriculture’s soil, the near surface layer is one of the most important layers for proper planting and their growth. It is the place where root system absorbs water and necessary nutrient are found here in the soil organic matter form. We can measure the near surface soil quality using indicators, such as physical and hydro-physical properties or soil organic matter content. The theoretical part of the bachelor thesis is focused on measuring those properties of soil, where the practical part’s objective is judging the effect of agrotechnology, based on the properties described in Czech and foreign literature. Those properties will be determined by using standard laboratory methods testing intact soil cores and grabbed soil samples. Those cores and samples were collected 4 times in total during vegetation period in 2016 in Šardičky (Vyškov district).

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.

Time variabilty of soil hydraulic properties and their impact on soil moisture estimation
Šípek, Václav ; Vlček, Lukáš ; Tesař, Miroslav ; Zelíková, Nikol ; Hnilica, Jan
The study was focused on the temporal variability of saturated hydraulic conductivity in an experimental plot covered by spruce forest and investigated benefits of its incorporation into soil water balance model. The results showed that the higher saturated hydraulic conductivity (33.6-44.8 cm hr-1) was observed in summer period compared to lower values (13.2-22.3 cm hr-1) in the winter period. The use of seasonally variabile saturated hydraulic conductivity improved the efficiency of soil water balance model in terms of lower root mean square error between observed and simulated volumetric soil water content by 33.2 %. The Nash-Sutcliffe coefficient rose from 0.34 to 0.68.
