| Popis: | Vertisols and vertic soils are known in a wide range of bioclimatic environments. The aim of this research was to identify possible vertic features in ultra-continental climate with gelic soil temperature regime with MAAT We found that Vertisols can form not only in cold environments, but also in ultra-continental cold environments with permafrost and negative mean annual air temperatures. However, their areas in Buryatia are limited in size to the warmest and driest positions in the landscape, namely south facing slopes. The discovery of Vertisols in ultra-continental climates will be a challenge for current soil classification systems, like Soil Taxonomy, which will need a provisional taxonomic category to accommodate such soils under gelic temperature regimes. We propose to introduce Gelert suborder and Vertic subgroup to Haplogeloll great group. |
