Correlation links of physiological groups of microorganisms with fertility indicators of degraded chernozem for different fertilizer systems

Goal. To develop a comparative correlation model of the interconnections ecological-trophic groups soil microorganisms with agrophysical, physicochemical indicators, humus condition, productivity degraded chernozem and to determine energy efficiency use intensive, low-intensive, organic fertilizer systems using by-products crops as fertilizers in 5-field grain-spray crop rotation for conditions Central Right-Bank Forest-Steppe. Methods. Field laboratory experiments, statistically analytical method. Results. Taking into account that intensive fertilization system causes an overdrying layer 0-20 cm, increases level moisture, it can be argued best preserving substance are created system. For low-cost systems, saturation complex Ca2+ is carried out by reducing chemical load on chernozem. That leads decrease metabolic acidity amplification biogenicity due growth number activity ammonifying, amylolytic, pedotrophenic, oligotrophic humus-extraction microorganisms, which provides reproduction agrocnosis short-crop rotation. Conclusions. system, density structure when drainage increases, enhances process mineralization extraction microorganisms. low-intensive there loosening cm chernozem, stimulates increase ammonifying pedotrophemical lesser extent, influences amylolytic
