Pre-anthropogenic evolution of biosphere based on mechanisms of struggle for life created dynamic stability of the Earth ecosystems comprised of species with maximum matching to all the biogeochemical niches. Intellect specific of only one species changed biosphere to support civilizations but at the same time interfered natural processes and transformed the state of the organized natural biogeochemical cycles. As a result, soil as the main basis of nutrients and biomass production is subjected to physical and chemical degradation and needs reclamation. To survive and develop as a species, Man should escape short-term decisions and use his knowledge and scientifically based approaches to find the ways for stable existence in changeable noosphere.
The main idea of the present session is to discuss the problem of optimization of eco-geochemical state of anthropized soil to improve the quality of agricultural and forestry production and, finally, human health in conditions of inevitable man-made contamination.
We invite specialists in soil science and all stakeholders to:
1) present their ideas and experience in assessment of the ecological and health risk due to soil contamination in their regions, countries and localities;
2) discuss how we should evaluate soil contamination in conditions of: a) natural nutrients deficiency; b) soil over-fertilization; soil pollution;
3) clear up what levels of elements concentration may be treated as pollution and demonstrate theoretical approaches and modern technologies that may be considered optimum in reclamation of technogenically transformed soils to improve their ecological quality and to contribute to human health.
