- Аннотация: Usually, soils changed by farming (agrogenic soils) are not shown on small-scale maps, the SoilMap of the Russian Federation, 1 : 2.5 M scale (1988), in particular. One of the issues of the map updating performedin the Dokuchaev Soil Science Institute is the introduction of agrogenic soils into the map contentsand representation of some of the former native soils as agrogenic soils on the updated map. Preliminarily, allnative soils shown on the map have been reclassified into the new Russian soil classification system. Agrogenicsoils in this system are separated as agro-soils in different orders and form a specific order of agrozems.Agrogenic soils have been identified in the soil polygons in agreement with the map showing the percentageof arable land in Russia as determined by I.Yu. Savin with coauthors (2020) and linked to the polygons of thesoil map. We have identified the classification position of the initial native soils involved in arable farming.Overall, 114 legend units representing agro-soils and agrozems have been identified. This number is dictatedby the diversity of native soils subjected to the agricultural impact producing their agrogenic modifications.Agrogenic soils on the updated map are shown in 4813 polygons out of the total of 25711 polygons. Chernozemsare characterized by the greatest diversity of agro-soils and the largest number of polygons containingdiverse agro-chernozems. The order of texture-differentiated soils is also rich in agrogenic soils, both agrosoilsand agrozems. Arable soils initially belonging to the order of Al–Fe-humus soils are present in a relativelysmall number of polygons and are represented only by Al–Fe-humus agrozems. The number of polygonswith participation of agrogenic soils and their proportion in the soil cover illustrates the geographicalpattern of their distribution, in particular, homogenous or mosaic patterns in the areas of different soil orders.
