Hydrothermal 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 s ...

The results of study of groups and forms of iron compounds in leached chernozemic soils of Western Ciscaucasia for three crop rotations according to scheme grain-grass-hoeing are presented. With long-term use of leached black soil in terms of Agrigento there is a substantial change in the contents of the various groups and iron compounds. On the non-fertilized variant of rotation, the total co ...
