CONTENT ADDITION TO THE STATE SOIL MAP WITH GENESIS INFORMATION OF SOIL PARENT MATERIALS AND GRANULOMETRIC COMPOSITION OF SOIL

Abstract

The substantiation of the first stage of works with the digital version of the State Soil Map (SSC) on elimination of differences on different sheets in the representation of genesis of soil-forming rocks, granulometric composition of soils and rocks is given. The content and characteristics of cartographic and literary sources containing information on the genesis of soil-forming rocks. Necessity of separate showing of granulometric composition of soil-forming rocks and soils on HCC is justified. Granulometric composition of soils on GPC is shown in the C horizon, which is a characteristic of deposits on which soils are formed. Granulometric composition of soils at description on of other maps is characterized by the upper horizons. On the example of specific analytical data of soils with differentiated granulometric composition of the profile shows ways to solve the problem.Granulometric composition of soils with undifferentiated granulometric composition of the profile is identical to that of soil-forming factors.
