Abstract:
Biological activity of the soil characterizes the soil fertility and it
reflects the ecological vocation of soil microflora. In this paper we present
the results of the eco-pedological and pedo-biological researches
accomplished in the forestry ecosystems (Quercus sp.) located in NorthEastern of Romania- Moldavian Plateau, county Iasi. The studies of soil
microflora pointed out the physiological activity (soil respiration and
cellulosolysae) and the enzymatic activity (catalase, invertase, urease and
total phosphatase) in the ecological conditions. Our results showed the
moderate to high values for physiological activity of the soil, moderate values
for enzymatic activity and low to moderate values for the indicators of soil
quality. These values pointed out the moderate to high levels, significant for
the biochemical processes of transformation of the organic matter, in the
humification trend and the partial mineralization of organic matter.
