Correlation between the legends of the 1:2.5 M soil map of the soviet union and the FAO soil map of the world

摘要

The legend of the 1:2.5 M Soil Map of the Soviet Union is the basis for the integrated soil informational space of the FSU countries. Its correlation with the system used by the UN Food and Agricultural Organization (FAO) makes it possible to relate it to soil nomenclature of other countries and to international standards of soil data interpretation.
