DescriptionHydrothermal conditions have a significant effect on catalase activity of soils of the South of Russia. The linear dependence of catalase activity in the upper horizons soils from average annual rainfall, aridity index of de Martonne and the coefficient of moisture of Mezentseva. In terms of catalase activity of the entire humus profile we revealed that the maximum activity has leached black soil, located in the medial climate conditions of the South of Russia
