Microbiological properties of Alluvial-meadow soil on flooded and non-flooded river terrace
- 1 ISSAPP „N. Poushkarov, Sofia, Bulgaria
Soil properties and hydrological regimes of flooded and non-flooded terrains create different conditions for soil microbial activity. The aim of this study was to characterize the microbiological properties of two profiles of Alluvial-meadow soil, situated on flooded and non-flooded terrace of the Maritsa River and to relate them to some soil physical properties. The main groups of soil microorganisms and the enzyme activity (β-glucosidase and phosphatase) of the soil were determined. It was found that soil characteristics and vegetation cover cause differences in microbiological properties. The soil profile from the first flooded river terrace of the Maritsa River was characterized by the largest amount of cellulolytic microorganisms. The heterotrophic microorganisms, mineral nitrogen – utilizing bacteria, microscopic fungi and actinomycetes prevailed in the soil profile on non-flooded terrace. Higher enzyme activity was also observed in this profile.
