The health, richness, and variety of microbial life in soil represent basic indicators for the evaluation and surveillance of forest ecosystem vitality. The vital role these microorganisms occupy in forest ecosystems underscores the necessity to in-depth assess and monitor their populations within soil habitats. Aiming to deepen our comprehension of microbial communities across different soils and soils horizons, we conducted an investigation of 22 soil profiles situated within the territory of Vitosha Nature Park...

The present study aimed to track the changes in microbial communities during home composting of biodegradable plastic products (PLA). 6 waste mixtures and controls were prepared, with C:N about 30, placed in containers. The amount of PLA compared to the compostable mixture is 1%. Different depositing methods were used - active composting and placing part of the material in biodegradable bags. Temperature, humidity, pH, C:N ratio were measured. The amounts of bacteria, actinomycetes, micromycetes were recorded duri...

Intercropping increases biodiversity in vegetable fields. It affects both above-ground and soil communities. The aim of the research was to study and analyze the soil microbiological and enzymatic activity in intercropping of cabbage with leek, green bean, tagetes, flower mix, and dill. The studies were carried out in two directions: 1) of microflora, as a sensitive indicator of the microbiological status of soils; 2) enzyme research, such as functional characterization and expression of microbial activity. Soil b...

Microbiological studies of forest soils are an important field of research due to the role of forest as carbon sinks and the main role of microorganisms in biogeochemical cycle and in the transformation of organic mass. Microbiological monitoring of soils in forest ecosystems is of key importance to achieve accurate and comparable data. This paper examines the interrelationship of soil microbial communities with different environmental characteristics. For the purpose of the study, the influence of soil type, the ...
