The paper considers and evaluates the effects of individual components in an integrated approach, describes in detail the synthesis of nanobiocomposite based on sludge waste biochemical treatment plant, extraction of components that have a significant impact on the aggregation of soil colloids, studied the main physicochemical properties of these agents. The effect of the concentration of nanobiosubstrate and its individual components (microbial exopolymers, nanoparticles of polyvalent metals, humic and fulvic acids) on the destabilization of soil particles in a long-term experiment (the report presents the results for the first 4 months). Analysis of the impact on the structure-forming processes of individual components of the sludge system showed that nanoparticles of polyvalent metals make the most significant contribution, slightly less affected by the action of humic and fulvic acids. Exopolymers have the least effect on aggregation processes. Rheological characteristics were studied, which additionally assessed the degree of restoration of soil structure. The enrichment of the degraded soil with the nanobiosubstrate developed by us promotes the development of thixotropic properties with coagulation structures in the system.
