Interakce mezi vybranými fyzikálními a chemickými půdními vlastnostmi v krajinném měřítku: detailní studie lokality Rudice na základě cíleného postižení prostorové heterogenity půdy v krajině
Vichta, Tomáš
In this bachelor thesis are assessed specified interacting physical and chemical soil properties of two main ecosystems (forest ecosystem, permanent grassland ecosystem) and their ecotone. Specifically, the detected soil properties, was determined by active soil reaction, soil reaction potential exchangeable, oxidizable carbon, total nitrogen, maximum capillary water capacity and minimum air capacity. For researches were chosen heterogeneous research area Rudice at TFE Křtiny Ml, the region of the Drahanska highland. In the work was used data obtained from spring 2016 (April), which has been then compared with data from autumn 2016 (October) and subsequently with each other, from physico-chemical point of view. Has been found that between some soil properties there was a change of values in two sampling dates and has been proved some certain correlation relationships between specified soil properties in permanent grassland ecosystem.

Vliv různých způsobů zpracování půdy na změny fyzikálních vlastností půdy
Hradilík, Hugo
This thesis studies the influence of different ways of soil tillage on changes in soil environment with focus on soil physical properties. In this work results from a long-term field experiment were assessed. As for physical properties, bulk density, total porosity and minimum air capacity were examined. The experiment took place at field experimental site of Mendel University in Žabčice. Soil physical properties of spring barley grown in monoculture and Norfolk four-course system after maize were studied. Two ways of soil tillage were compared – ploughing and shallow loosening. The results of measurements in 2016 and 2017 were applied. The results showed that conventional tillage using ploughing reduced bulk density and raised total porosity in contrast with minimum tillage. Conventional tillage raised minimum air capacity. Regarding shallow soil loosening, the positive effect of crop rotation in Norfolk system on bulk density and total porosity was proved. Ploughing in monoculture showed higher levels of minimum air capacity compared to the crop rotation.
