Item type:Article, Access status: Open Access , Relationships between microbial and chemical properties in mine soils reclaimed for forestry(2010) Chodak, MarcinMeasurement of several microbial properties is necessary for comprehensive assessment of mine soils. Therefore, the applied methods should maximize amount of acquired information. Objectives of the work were to assess relationships between microbial properties of mine soils and to assess of their dependence on some soil chemical and physico-chemical properties. The measured microbial properties included microbial biomass, basal respiration, activities of dehydrogenase, acid phosphatase and urease. Biolog® assay was used to assess physiological properties of soil microbial communities. The chemical and physico-chemical properties included the contents of C, N and pH in KCl. Spearman correlation was applied to study relationships between the properties measured. Most of microbial properties were correlated with each other. However, the Biolog® derived parameters weakly correlated with Cmic and enzyme activities what indicates that they bear complementary information on soil microbial communities. Activities of acid phosphatase and urease depended mainly on microbial biomass. Positive correlation between Shannon index based on Biolog® data and microbial biomass indicates that in the mine soil the physiological abilities of microbial communities increase as increases the microbial biomass.
