Rezumat

Through the lens of the concept of applying substances of humic origin for soil fertilization purposes, bioorganomineral preparations of humic origin represent pedogenetically active substances, „carriers of the pedogenetic code”, the administration of which in the rhizo- and phyllosphere contributes to the intensification of micro- and meso-pedogenetic processes that take place in soils and manifests itself in the sustainability of substance and energy exchange processes in the "soil-plant" system. In the present research, the influence of solid and liquid bioorganomineral preparations obtained through the biological recycling of waste of various origins on the direction and intensity of pedogenetic micro- and meso-processes was evaluated. It has been established that their administration contributes to the improvement of the pedofunctional system [bioenergetic system ↔ structural-aggregate system] with quantitative manifestations in the characteristics and regimes of the soils. In the composition of the humic system of soils, the total content of humic acids increases and that of fulvic acids decreases. The relative content of the unhydrolyzed residue is slightly reduced. In the composition of the aggregate system, the content of agronomically valuable aggregates (10-0.25 mm), agronomically precious (5-1 mm) and grainy chernozemous aggregates (3-1 mm) increases. At the same time, the intensification of phosphorus mobilization processes can be seen in the soils as a result of the improvement of their state of settlement and the intensification of phosphatase activity. The cellulolytic activity of the soils intensifies significatly, but this, however, is largely dependent on the climatic conditions.
