- Аннотация: Soil contamination is one of the key factors of land degradation due to disturbance of natural soil environment functioning. These harmful changes lead to decreasing of ecosystem primary production and further problems of deforestation and desertification. Climate change, coupled with pollutant exposures, may have potentially serious adverse consequences for natural ecosystems in contaminated regions. In our research we evaluated possibility of application of different organic, mineral and biological amendments for remediation of multicontaminated soils of industrial barrens near Ni-Cu smelter in the Kola Peninsula, Russia. These barrens, the last stage of technogenic transformation of the initial coniferous forests, are characterized by complete absence of vegetation, depletion of nutrients and organic matter, and development of erosion processes. We provide both laboratory and field experiments to show effect of commercial applicants – coal humate, peat-gel, biochar, mycorrhizae infection in combination with and compare to NPK-fertilizer and calcium carbonate – on test-culture and soils at different stages of contamination. We can conclude, that organic amendments may be recommended for remediation of contaminated soils due to promotion of heavy metals stabilization, nutrients enrichment and test-culture growing. Further enhanced ecosystem production in response to proper soil management can contribute to carbon sequestration in the vast degraded lands.
