Healthy soil as a necessary condition of human life

摘要

The extent of soil degradation and soil pathology in Russia is discussed. The concept of a federal target program "National System of the Chemical and Biological Security of the Russian Federation (2009-2013)" is examined. A definition is given to healthy soil of agrocenoses and its main functional characteristic-ecological stability (including balanced biodiversity, self-cleaning capacity, and suppressive activity of the phytopedocenosis). Urgent applied scientific problems of regional soil sanitation are formulated. Criteria and modern methods of ecological monitoring and assessment of soil quality and health are considered. A systems approach to sanitation of soils infected by highly harmful phytopathogens-the causative agents of root rots of cereal crops-is demonstrated using the induction of soil suppressiveness as an example.
