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.

Hodnocení fyzikálních vlastností půd v podmínkách trvale udržitelného vývoje vinic =: Evaluation of the physical properties of soils in conditions of sustainable development of vineyards /
 Jankovičová, Marta
This dissertation deals with the influence of the application of two different doses of compost on the change of selected physical properties of soils. Experimental sites (Lednice, Klentnice, Velké Bílovice) with different soil conditions were selected for experimentation purposes in the wine-growing region of South Moravia. Experimental measurements were performed from autumn 2013 to autumn 2016. Sampling of intact soil samples using Kopecky physical cylinders was carried out in nine variants at each site, respecting intergranular maintenance management, spatial zoning and compost batching. The physical properties were mainly monitored by the weight reduction (OHR, g. cm-3) and the total porosity (P %) which, as significant aspects, predict soil compaction. On the basis of analyzes of physical properties, pedocompact rate was found in all experimental vineyards, while the positive effect of organic matter in the form of compost on the values of OHR and the total soil porosity was demonstrated.
