Resumo
The study of soils of different ages developing on the drying bottom of the shallow-water Yudinsk reach of Lake Chany (Western Siberia) has shown that soil salinization is a powerful factor affecting the biomass and metabolic activity of microorganisms. Strong salinity of parent materials retards the development of microbial population in the young soils. With an increase the soil age of lake depressions, desalinization takes place, and the rate of the formation of microbial biomass increases. Its metabolic activity becomes more pronounced, though the specific rate of metabolic activity slows down. The carbon of the microbial biomass and basal respiration in the soils developing on drying lake bottoms in the forest-steppe zone reach the values typical of the zonal chernozemic soils in about 80 years.
