Forest Ecosystems
The status, abundance and diversity of soil microbial communities are one of the main basic indicators for the assessment and monitoring of forest ecosystems. In the context of the important role that microorganisms play in forest ecosystems, it is crucial to study and monitor their abundance in soil habitats. In order to supplement the knowledge about the soil microbial communities in the different soil horizons, we studied 16 soil profiles from the territory of Vitosha Nature Park. The soils from tested areas 1-8 are determined as Dystric Cambisols and the soils form tested areas 9-16 as Umbrisols. The main soil characteristics: pH, total nitrogen content, humus and organic carbon content have been studied using standard laboratory analyses. The total microbial number of the individual soil horizons have been established respectively for the Dystric Cambisols A and B horizons, for the Umbrisols A1 and A horizons. The Koch method was used. The percentage distribution of the main microbial groups: spore-forming and non-sporeforming microorganisms, actinomycetes and micromycetes have been determined. For all studied soils, a decrease in the total microflora with an increase in the depth of the soil profile was found. In Umbrisols this decrease is less compared to Dystric Cambisols. In both soil types, the results show a significant reduction in the group of micromycetes in the underlying soil horizon, regardless of soil type. In soils with higher acidity, a higher percentage of the micromycetes is observed, regardless of soil type and soil horizon. Higher values of the correlation coefficient were found when comparing the microbial abundance in the lower soil horizons with the humus content, compared to the upper soil horizons.
