What is the soil in arctic deserts?

The soils of the arctic deserts are subdivided into two muds – arctic desert and arctic typical humic soils. The soil-forming process in the arctic deserts is hampered by low air temperatures, which do not give normal thawing of soils. The presence of humus, which gives soil fertility, in these soils is very small, about 1-2%, which also affected the vegetation of these places. The main species growing on these lands are mosses and lichens.
