Грибы в городских почвах: биомасса, распространение, функции

Abstract

Urban soils with woody and herbaceous vegetation differ in the level of content and seasonal dynamics of alive fungal biomass, and enzymatic cellulase activity. Compared with the zonal and other urban soils, Urbic Technosols Humic contain the least amount of alive fungal biomass. A bit higher content of alive fungal biomass was found in Urbic Technosols Novic, which were artificially constructed using soil remediation mixtures. The highest content of alive and active fungal biomass was found in Terric Techniс Retisols and background Albic Retisols of urban parks. An activity of fungal CO2 emission increased to the maximum in the fall. The content of the alive fungal mycelium in these soils was highest in late summer. And in winter its content was the same as during the growing season. The assemblages of cellulolytic fungi in urban soils were depressed. We have showed the possibility the development of cellulolytic fungi in urban soils in the cases of the addition of litter, remediation mixtures and wood chips.
