Аnnotation Purpose. Justify the possibility and feasibility of using the technological standard (Tn) to regulate the technological load on soils to eliminate the conditions of their degradation using the energy assessment of the action of agricultural machinery systems and agronomic measures in terms of the structural-aggregate and humus state, as well as biological activity. Methods. General scientific (field, morphological-genetic, comparative-analytical, agroanalytical, laboratory) and special (determination of the content of elementary soil particles (ESP) and microaggregation by the microscopic method according to Bulygin S. Yu.). Results. Under the conditions of stationary experiments of the Right-Bank Forest-Steppe of Ukraine, it was revealed that more than 60 years of use of alkaline chernozem soil in a 10-field crop rotation with a field of clover with a traditional tillage system using moldboard plowing against the background of different fertilization options did not significantly worsen any of the parameters of agrophysical and humus state, biological activity, quantitative and species composition of the microbiological pool. More than 40 years of use of dark gray podzolized soil at a full rate of fertilization, applying lime to neutralize hydrolytic acidity and growing green manures after cereal early ripening crops, leaving the non-marketable part of the crop on the field under the conditions of a traditional processing system with moldboard plowing in a 7-field crop rotation , also with a field of clover, did not worsen the main parameters of its fertility. A conceptual mathematical model has been developed for the processing soil conservation agriculture systems based on the studies. Conclusions 1. Agrophysical parameters of soil have different information content and different sensibility. Each hierarchical level of the soil body system is characterized by a certain set of indicators, including agrophysical ones. It has been established that a scientifically grounded crop rotation against the background of moderate doses of mineral fertilizers, necessary chemical ameliorants with the abandonment of the non-commercial part of the crop and the use of green manure after early grain crops guaranteed to hold the agro physical condition of soils from deterioration. 2. The guarantor of a quasi-stable humus state is the stability of the agrophysical framework of the soil system and the harmony of the microbiological pool, the quantitative and species composition of which determines the balance of the synthesis and mineralization of humus and other organic substances. 3. Changing the effective influence of the living soil phase is determined by its agrophysical state, which leads to a change in the humus state – the first iteration passed. Next – the next and next chain of the spiral of the “life” of the soil (thesis-antithesis synthesis by Hegel), until the bottom or the top of the dynamic equilibrium is achieved, which is determined by the level of agriculture culture. 4. The direction (vector and trend) of the soil formation is determined by the energy ratio of the energy of the Sun in the form of a fresh vegetable residue (the second factor of the genesis of soils according to Dokuchaev) to anthropogenic energy, which is consumed in the implementation of crop technologies, which determines the value of the technological regulation (Tn). 5. The energy assessment of technologies for growing crops under the conditions of long-term stationary experiments made it possible to determine technological standards (Tn): for meadow-chernozem soil – 8.6, for dark gray podzolized soil – 7.2. Keywords: technological standard of energy load, elementary soil particles (ESP), coefficient of microaggregation, humus state, microbiological activity, energy assessment of plant technologies.
