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. |
