Effect of basic agrotechnics for physical and hydrophysical properties of soil
Komárková, Markéta ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
In the master’s thesis, we evaluate the impact of different types of soil treatment on the physical and hydro-physical properties of the subsurface layers of soil. The experimental research took place near the town of Šakvice in two chosen areas treated conventionally, i.e. by tillage. The PRP SOL substance was applied to one of the observed areas. Unimpaired soil samples were taken during the vegetation period of the grown crops in the topsoil (10,20 cm) and in the undersoil (30 cm) on 13th May 2009 and on 10th September 2009. The chosen physical parameters of the soil, i.e. the reduced volume mass, the porosity, the distribution of pores, the actual content of water and air, were determined by standard analytical methods. The double-ring infiltration method was used during the field measuring of infiltration. The Philip’s equation and the Philip’s type three-parameter equation were used for the data analysis, serving as a base for estimation of saturated water content Ks. A protractor with a constant gradient was used during laboratory measuring. The results of a year-long research have not shown any major influence of the PRP SOL substance on the physical quality of the subsurface layers of soil in the observed area. On the contrary, the permeability od the soil obtained on the basis of Ks estimation is higher in the area treated by the PRP SOL substance.

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.

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.
