Landscape geochemical phenomena were shown to be significant factors in the formation of soils in large regions and in combinations of soils from elements of the meso- and microrelief (V.

The first subdepartment of soil geography was founded in 1926 at Leningrad University by S.

Following Dokuchaev’s scheme of soil zones of the northern hemisphere, they compiled a number of quite detailed soil maps of the world (K.

New data on the geography of foreign soils were obtained by Soviet soil scientists while working in East and Southeast Asia, Central Europe, and Cuba (I. a branch of soil science that studies the pattern of distribution of soils on the earth’s surface for the purpose of soil-geographic regionalization. General soil geography studies the factors that influence soil formation and the most general laws of the geographic distribution of soils and types of soil structure. Regional soil geography is concerned with regionalization and with the description of the soils in individual regions. Soil geography relies principally on the comparative geographic method to study the distribution of soils in relation to the factors influencing soil formation. Extensive use is made of cartography in the compilation of soil maps. The new technique was applied in soil surveys carried out in different regions of European Russia and in the compilation of the country’s soil map. The accumulation of data on the soil geography of plains and mountains in both Europe and Asia led to the discovery of the patterns of soil distribution. Soil-geographic explorations and soil mapping expanded enormously during the first few decades after the Great October Revolution.
