Peculiarities of the Succession Process in the Microbial Complex of Alluvial Soil under the Change of Vegetation Type
A. A. DANILOVA
Abstract
During 18 years after sowing the natural vegetation in arable soil, the abundance of fungi increased by 40 % and amounted to 50-60 % of that under natural forest. The abundace of microorganisms utilizing various nitrogen sources and oligotrophs decreased therein by 20-30 % and exceeded respective parameters under forest on the average by 30 %. The rate of change of the abundance of some or other group of microorganisms during restoration of natural vegetation on arable soil was determined by its place in the trophical chain formed in the process of decomposition of vegetable litter.
