This presented bachelor‘s thesis deals with a determination of a granular composition of a extracted fraction from fields by the laser granulometry method and a comparison of results obtained from the pipetting method and a known eolithic sediment. In the first part of this thesis, basic problems of the wind erosion are mentioned as in the world as in the territory of the Czech Republic and Slovakia, counter-measures and methods of measurement. 8 samples from autumn 2017 and 8 samples from spring 2018 were compared from South Moravian and Trnava region with potential occurrence of wind erosion. In the comparison, differences were found between source (rising) and basic fractions. In the conclusion, a comparison of the individual fractions with the reference samples was performed. |
