Faktor vegetačního krytu v kontextu efektivní protierozní ochrany zemědělské půdy

Aim of this diploma thesis was to study the protective effect of vegetation from the point of view of the two most common types of erosion in the Czech Republic, water and wind. The theoretical part of the thesis is focused on the degradation processes occurring in the soil, the threat of agricultural land by water and wind erosion, with a focus on wind erosion. Based on the analysis of data from the selected stations, changes in phenological occurrence of selected crops, sugar beet and corn were examined. The issue of changing climate and its influence on the course of wind erosion was characterized. On the other hand, soil erosion control was described based on the rules of GAEC (Good Agricultural and Environmental Conditions) where critical periods of growth of field crops are limited. In the practical part, the Mann-Kendall test was performed; based on this test changes in the onset of phenological phases and agrotechnical operations were found. Furthermore, the areas which are most endangered by wind erosion (Tvrdonice, district Břeclav) were defined, where based on the identification of critical periods field measurements were performed with deflameter and monitoring of erosion occurrence. Subsequently, qualitative parameters of soil particles were found on the basis of the spectral analysis of the deflametric record in the period of dangerous erosion episodes
