Abstract
The focus of the study was on the dynamics of the variation in the
population of copiotrophic and oligotrophic bacteria and actinobacteria as
well as the level of acid and alkaline phosphatase activities taking place
during pine bark composting, depending on the application of different
organic admixtures and the Effective Microorganisms microbiological
preparation as well as variation in pH values and temperature. Above all,
the trend in the variation in the population of microorganisms under
analysis and enzymatic activity depended on the type of admixture applied
to the composted pine bark. Apart from that, the course of microbiological
activity was also influenced by temperature variation, which resulted from
the course of the composting process. The results obtained in the
experiment proved that the admixture of PGM (plant green matter) to the
composted prisms had stimulating influence on the microbiological indexes
under analysis.
