Pedotransfer functions for estimation of moisture retention curves of medium-heavy soils of South Moravia
Gavlasová, Iva ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
The most important characteristics of each soil is its hydro-physical properties, which include retention curve. Retention curve expresses the relationship between humidity and pressure head. It is course affected by many factors such as grain size and mineralogical composition, humus content, structure and bulk density of dry soil. This thesis deals with direct and indirect determination of one of the basic hydraulic characteristics of the soil, soil moisture retention curve. For laboratory determination of moisture retention curves were used for sand tank and pressure instruments. Measured body retention curves were optimized RETC program.For indirect determination of retention curves were used Pedotransfer function by Wösten et . al .(1998 ) , derived from the European soils and under HYPRES Šútora and Štekauerová (2000). As in the project Wösten et al . (1998), PTF were processed for arable land in the area. The accuracy of both models PTF was assessed by the correlation coefficient R and standard error RMSE. Simple models PTF provide estimates of retention curves with sufficient accuracy for practical use in the locality.

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).

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.

Use of family house rainwater for irrigation and soaking
Sirůčková, Renáta ; Kameníčková, Ivana (referee) ; Hyánková, Eva (advisor)
This bachelor thesis is focused on problems of rainwater and their use. The thesis is divided on two parts, theoretical and practical. The first part of the thesis deals with the general distribution of rainwater, from the creation of individual precipitation, their composition and quality, up to their surface runoff. Further, the individual possibilities of their cleaning and subsequent accumulation and soaking are analyzed. Part of the work is also the use of rainwater from the household to the garden. In the second part the specific location for the use of rainwater around a family house is solved. The specific location is situated in the village Voleč in the Pardubice Region. Here is a complete solution accumulation of rainwater, irrigation and soaking.

The effects of land management on the physical quality of subsurface soil layer
Komárková, Markéta ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
The thesis deals with the influence of soil cultivation on physical quality of the subsurface soil layers (horizons). The experimental research has been conducted nearby Šakvice on two different areas which were both cultivated in an ordinary way, e.g. by tillage. One of the two areas was exposed to PRP SOL subsidiary substance. Undisturbed soil samples were drawn in three different soil depths: 0,1, 0,2 and 0,3 m. Samples were drawn on May 13, 2009 and September 9, 2009 during the vegetation period of the grown crop. The selected physical properties of the soil, e.g. the specific gravity of the soil, porosity, poruses division, actual presence of moisture and air, were assessed using standard analytical methods. The results of a one-year research did not give evidence of a strong effect of the PRP SOL subsidiary substance on the physical quality of the subsurface soil layers.

The effect of soil structure on the hydraulic characteristics of the soil
Čermák, Petr ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
Soil is very important in the hydrological cycle of landscape. The retention and storage ability depends on the quality, type of structure and other properties of the soil. The retention ability of soil is determined by gravitational pores (the coarsest pores), which are drained off after filling the water. The accumulation depends on the capillary pores in which water is bounded by capillary forces. The soil works also as a filter´s environment which cleans naturally the water. This process can be also converse, when various substances are released from soil to water. The state and amount of water between the surface of soil and level of groundwater affect many important processes such as fertility of soil, drain from drainage area, supply of groundwater sources and others. Structure of soil changes fundamentally by cultivation of soil and types of farming crops. Aggregates are mechanical destructed by weather conditions and soil gradually loses its good qualities, fertility is reducing and flood protection is decreasing. This fact can be avoided by right choice of crops and the type of tillage soil.

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.
