Involvement of Soil Microorganisms in C, N and P Transformations and Phytotoxicity in Soil from Post-Industrial Areas Treated with Chemical Industry Waste

Soil degradation is an unavoidable phenomenon that poses a real threat, as it limits soil utility and reduces its resources. Early assessment of can prevent further deterioration. Various parameters microbial activity may be helpful in this evaluation. Therefore, the purpose study was to assess usefulness microbiological (total abundance oligotrophic bacteria filamentous fungi), biochemical (soil respiration) enzymatic (dehydrogenase, protease, acid alkaline phosphatase fluorescein hydrolytic activity) indicators, well phytotoxicity, monitoring condition chemically degraded soils due severe alkalization. The experimental material collected three sites located at different distances from reservoir with liquid post-production waste. analyzed indicators were correlated physical chemical properties variants level sampling sites, profile seasonal variability. All showed significant changes their individual sites. location closest waste characterized by lowest values discussed activities highest phytotoxicity. Individual also depending on season layer. Considering exposed degradation, total bacterial fungal counts, proved most sensitive indicators.
