Abstrakt: Glomalin is being investigated as a substance that improves soil quality, the resistance of soil aggregates and play a role in carbon sequestration. This study is the first nationwide survey of the glomalin content in the soil. Soil samples were collected from 181 locations in the Czech Republic to describe the variability of glomalin content in the soils of the Czech Republic and its dependence on soil chemical properties and climatic area. Sodium citrate buffer was used to extract easily extractable glomalin (EEG), and the glomalin concentration was determined spectrophotometrically. The soil glomalin content correlates most with the ratio of humic and fulvic acids. Moreover, the interrelation between glomalin content and climatic regions was also observed. The content of glomalin decreases from the warmest regions to the coldest. We also compared the glomalin content among different soil types groups and found out that the lowest glomalin content was found in Entic Podzols and Gleysols. On the contrary, the highest glomalin content was found in Vertisols, Phaeozems and Luvisols.
