Pankova E.I., Yamnova I.A. MANIFESTATIONS OF SALINITY AND SOLONETZICITY IN ZONAL SOILS OF MONGOLIAN DRY STEPPES // Arid ecosystems. 2021. V. 27. № 1 (86). P. 43-53. | PDF

The taxonomic position of dry-steppe (chestnut) soils mentioned in the books Classification and Diagnostics of Soils of the USSR (1977), Classification and Diagnostics of Soils of Russia (2004), and World Reference Base for Soil Resources (2014) is discussed. Based on the example of the soils of Mongolia, it is shown that the soils of dry steppes that formed on arenic nonsaline parent rocks are normally nonsaline and nonsolonetzic. The soils of Mongolian dry steppes that formed on saline rocks are saline and solonetzic. The soils with profiles that include loamy layers (even those with a predominantly light granulometric composition and formed on nonsaline rocks) normally feature signs of solonetzicity in the loamy horizons.

Keywords: chestnut soils, cryoarid soils, kastanozems, salic and solonetz (natrik) horizons.
