Structure of a database of national digital map of stores of organic carbon in soils of Ukraine

Abstract

The purpose. To develop structure of database for assessment of stores of organic carbon in soils of Ukraine according to specifications of Global soil partnership of Food and agricultural organization of United Nations (FAO-GSP). Methods. Scientific analysis, generalization and mathematical statistics. Results. Attributive database which contains necessary indexes for creation of national digital map of stores of organic carbon in soils of Ukraine by means of digital mapping and simulation of soils is developed. Attributive part of the database consists of 6 messages and contains the list of indexes describing places of soil profile, methods of determination of soils’ properties and calculation of stores of organic carbon in soils of different type of land-use in conformity with specifications of Intergovernmental commission of experts on climate fluctuation. The designed database structure ensures the opportunity to derive representative data file for generalization and integrations with national database «Properties of soils of Ukraine» of NSC «A.N. Sokolovsky Institute of soil science and agrochemistry». The framed database includes the period of field investigations of soil covering beginning from 1959 up to 2016. Content of database is integrated into Global digital map of stores of soil organic carbon of FAO. Conclusions. The offered structure of database may be used for development of similar specialized relational databases with the purpose of their application in digital mapping and simulation of soils. Creation of the specialized processing center with the uniform harmonized system of storage of information on the state of soil covering will ensure an opportunity of its use for scientific researches and formation of soil-protecting policy of the state.
