Formation of links between microorganisms of certain groups in haplic luvisol under the influence of mineral fertilization and liming

The aim of the research was to form connections between separate groups microorganisms as a part gray forest soil (Haplic Luvisol) during cultivation spring wheat with use various fertilizers and liming systems. Research methods: microbiological, laboratory-analytical, statistical. carried out in landfill monitoring system on basis stationary experiment Department Agrosoil Science Soil Microbiology at NSC “Institute Agriculture NAAS” - Development improvement intensive technologies agricultural crops expanded fertility reproduction. main results study: number ammonifiers is positively correlated total (0,955), mineral nitrogen immobilizers, denitrifiers, nitrifiers, cellulose-destroying bacteria, actin- micromycetes, coefficient mineralization compounds, biological activity (0,911). conclusions previous are confirmed: Azotobacter not diagnostic microorganism for effective fertility, evidenced by insignificance correlation coefficients yield (0,265), winter (0,131), soybeans (0,303). correlates inversely most studied indicators, especially significant polysaccharide-synthesizing microorganisms, actinomycetes, melanin-synthesizing micromycetes (-0,719), acid-forming (- 0,611), physiological biochemical own cells, pedotrophic index. direct nature relationship established group optimal nutrition plants immobilizers (0,854), pedotrophs (0,970), cellulose-destructive (0,724) autochthonous (0,878) (0,588), probability colony formation coefficient, (0,646). Indigenous show high level dependence pedotrophs, denitrifiers cells (0,935).
