Abstract
Is definite the quantitative and quality composition of chernozem usual and southern streptomycetes cenosis. It is rotined that humus horizons of chernozem usual more biogenic, than chernozem southern. Analysis of specific structure of streptomycetes association and calculation of some biodiversity indexes by Margalef, Berger-Parker and Serensen it was allowed to set the specific features of forming of these microorganisms cenosis in investigated soils.
Highlights
Different subtypes of chernozems differ as on microorganisms quantitative composition, including, streptomycetes, so on microorganisms taxonomical groups correlation in a cenosis (Sherbakov et al, 1983)
Comparative researches in relation to streptomycetes participating in forming of microbal cenosis of chernozem southern and chernozem usual in a steppe area not conducted
The conducted researches were showing the presence in chernozem soils of features of microorganism’s, which assimilates mineral nitrogen, amount fluctuation
