Fyzikální vlastnosti povrchových horizontů půd vybraných lokalit
Psotová, Petra
This bachelor´s thesis focuses on the evaluation of some physical properties of surface horizons of soil under the Giant Mountains. They come from three villages. In every village I took four samples of arable land and four samples of permanent grassland. An average of these results was created for each village. Soil samples were collected into core sample holders. In a review of the literature there are described the physical properties of soil, the procedure for processing results and the characterization of selected locations from the climatic, pedological, geological, hydrological and agroecological point of view. The resulting average values are, to a porosity 41,8 %, density 1,54 g.cm-3, specific gravity 2,6 g.cm-3, the minimum air capacity 6,7 % and a maximum capillary water capacity 35,1 %. According to the classification of grain on these locations are found mainly middle heavy soil, loam and sandy loam.

Vybrané fyzikální parametry jako indikátory kvality půdy
Kratochvílová, Lucie
In bachelor thesis "Selected physical parameters as indicators of soil quality" we aimed at soil physical properties in Luvi-HaplicChernozem (locality Praha-Ruzyně) and Haplic Cambisol (localities Vatín and Svárov). We followed texture, density, bulk density, porosity, micro and macro aggregates composition, and stability of aggregates. Also content and quality of soil humic substances was determined. Obtained results showed that there is a linear correlation between clay particles content and humic substances content and humification degree. Reversed correlation was found between clay particles content and aggregates stability and structure coefficient.
