The actual and permissible acidity levels on the territory of the Asian part of Russia are evaluated. The critical acidity load was chosen as a measure of stability. To show the actual amounts of precipitation affecting the acidity balance in soil, sea-salt correction was applied. Such main calculated characteristics as precipitation of acid and base compounds, total acidity load, and critical acidity loads are mapped. It is shown that the critical acidity loads on the territory of the Asian part of Russia vary from 0 to 7 kEq ha-1 yr-1.
