Agriciltural microbiology| Резюме: | The influence of the system of fertilizers on the number of phosphorus-mobilizing microorganisms as the component of microbiocenosis of meadow chernozem was studied. It was established thatamountofphosphorus-mobilizingmicroorganismshadnotcorrelated with phosphoric mineral fertilizer dose applied in crop rotation and degree of phosphorus mobility in soil and was determined apparently by the availability of carbon-bearing substratum. It was also shown that in variants with artificial PK-background and annual mineral fertilizer use the raised contents of phosphorus mobilizing microorganisms, pedotrophs, cellulolytic microbes, oligonitrophyls and the immobilizers of mineral nitrogen was observed. In the soil of extensive variant the content of mineral nitrogen immobilizers and azotobacter was maximized. Utilization of organic material had exceeded its syntheses in all studied agricultural backgrounds. |
