For fifty years since its establishment in the early 1890s, the Czechoslavic Ethnographical Society was the principal representative of the field in the area of present-day Czech Republic and Slovakia. It was the centre of folk culture research; no other comparably significant institution existed in this area. The history of the Czechoslavic Ethnographical Society is interwoven with interdisciplinary relationships.The reason is that the people, who had helped to create this association up to the 1930s, did not engage themselves fully and professionally in ethnography as their only or at least main discipline. It was due to the fact that there was sparsely any workplace where they could find any existential and scholarly background. Inspiration was thus brought in by people from different fields that had a close relationship to folk culture. The same went for principal bodies of this ethnographical institution which were formed by experts from different disciplines, including the membership base which often counted above a thousand people actively interested in folk culture. the leadership of the society endeavoured to actively employ these people, often experts from different disciplines or significant regional workers, in documentation of folk culture. This was apparent predominantly during preparation and compilation of ethnographical encyclopaedia in the 1920s and 1930s. Although it remained unfinished, it has been one of the chief projects of Czech ethnography in its history.
Water erosion has been recognized as a major soil degradation process worldwide. This is of special relevance in the semi-arid areas of South Bulgaria with long periods of drought along with severe rainfall events. The main objective of this study was to evaluate the applicability of Bromus innermis L. and Lotus corniculatus L. for soil protection purposes under different site conditions. The site parameters considered were slope, fertilization and a range of soil physical parameters. The plant parameters were canopy cover, biomass, and root morphological characteristics. The experiment includes plots without and with eleven rates of NPK fertilization on gentle (6o ) and steep slopes (12o ). It was observed that the effect of fertilization on shoot and root growth was stronger on the gentle than on the steep slopes. The biomass accumulation was more sensitive to N than the PK fertilizer applications. The increase of the root density with increasing fertilization rates was more pronounced for the mass than for length or surface area. A significant effect on root diameter was found only for the variants with the highest N application. Treatments with the highest root mass density on both slopes showed the greatest potential for reducing erosion.
