In May 2019 the team from University of South Bohemia excavated pluzina field systems near the castle Rokštejn in Vysočina region. These pluzinas are not so visible in terrain and it was the reason for choosing them for comparing the difference between Valštejn and Oblík. One of the hedgerows was excavated and soils samples were taken for other analysis. In the alluvial of Brtnice river was cored the profile by the pedological drill. These obtained samples will be analysed for determination of the past local vegetation cover by the pollen analysis.
