The basal respiration, microbial biomass and value of
metabolic quotient of microbial associations (qCO2) in the brown soils of the
64 coniferous, mixed and deciduous forests in the margins of 300–1200 m above
sea level of protected and forest land use territories of the Western
Carpathians has been studied. Analysis of the dependence between microbial
activity and biomass for all samples (n = 64) resulted in an inverse hyperbolic
relationship. Established that proportionate increase of quantity the active
microorganism cells and decrease of the total microbial biomass is consequence
of energetic optimization in soil of forest ecosystems and its adaptation to a
soil conditions.
