Database of agricultural soils of the Western Sayan

Abstract

Based on the long-term soil research, the database “Agricultural Soils of the foothills of the Western Sayan of Khakassia” with a wide range of soil characteristics for various purposes and uses was formed and registered. The database contains attribute information about the current state of arable and postagrogenic soils in the foothills of the Western Sayan of the Republic of Khakassia. The set of independent materials is presented in the form of tables, queries, forms, reports and catalogues of text files (docx), photos (JPEG), which contain information about soil forming factors, soil classification and distribution by natural and climatic zones on the research territory. Currently, the database includes a description of 17 representative soil profiles with an optimal set of indicators, a detailed description of each pedologic horizon, an accurate geographical reference and a digital photography of each reference soil profile. It contains the taxonomic attribute of the dominant and codominant soils in various classification systems (SC RF; WRB, 2006; FAO, 1988). The main information object is the type (subtype) of soil, which includes systematized factors of soil criteria (a list of 18 sets): morphological description of the soil profile, indicators of pedological property, chemical, physical and chemical, agrophysical, hydrophysical and other indicators.
