Opis:: The issues of soil fertility preservation are relevant in all countries of the world. Concrete actions, technological and organisational solutions allowing to overcome this complex and continuous phenomenon by using exclusively agroengineering approaches are proposed. The preservation of the structure of agricultural soils requires urgent adoption of technological and organisational decisions in the following areas: maximum limitation of immobilisation of nitrogen in the soil after introduction of organic residues into the soil; development of technological methods and tools for the soil cultivation, aimed at loosening the surface layer of the soil with a minimum area of its contact with the airborne environment; improvement of the fundamentals of aggregation of agricultural machines, taking into account the maximum permissible slipping of wheeled energy facilities at the level of 15%, and a conceptual approach to their ballasting with respect to the requirements of the tire ecophilicity; application of a soil structure indicator when determining the ploughing frequency by means of ploughs with skimmers or their twotier analogs; wide practical application of the controlled traffic farming system; adoption of a legislative document on specific conformity of the land users for the level of soil fertility for agricultural purposes.

Opis:: The humus content in the soil is the most important factor affecting the yield of agricultural crops. The research of the impact of the soil cultivation methods upon the humus content is an urgent scientific and practical task of modern agriculture. This paper analyzed long-term (45 years) field experiments on the impact of ploughing, deep and shallow non-moldboard tillage upon the humus content in the chernozem soil of central Ukraine. The research materials reflect a broad picture of influence of the processing methods upon the accumulation of total humus. For example, with respect to ploughing with deep non-mouldboard cultivation, accumulation of the total humus in the 40th year of research, was +0.0028%; with shallow non-mouldboard cultivation it was +0.0005%.

Opis:: The negative impact of global and regional climate changes upon the crop yields leads to the violation of the crop production stability. The development of reliable methods for assessment of the climatic factors by the reaction of the crops to them in order to minimize the impact of climatic stresses upon the sustainability of food systems is an urgent scientific task. This problem was studied on the example of growing corn. A mathematical analysis of the main meteorological indicators for 16 years of research has been performed on the basis of which the frequency and direction of the occurrence of atypical and extreme weather conditions in various periods of the corn vegetation season were established by the coefficient of significance of deviations of the weather elements from the average long-term norm. It has been proved that the probability of occurrence of such weather conditions in the period from April to September is 38–81% in terms of the average temperature of the month, and 31–69% in terms of precipitation. By using the information base of the corn yields in a stationary field experiment with the gradations of factors: A (the fertilizer option) – A1-A12, B (the crop care method) – B1-B3, C (the hybrid) – C1-C7, the most critical month of the corn ontogeny was established when the weather has a decisive influence upon the formation of the crop. With the help of the correlation-regression analysis it was proved that the corn yield most significantly depends on the average monthly temperature in June, and for the hybrids with FАО 200–299 – on the amount of precipitation in the month of May. The obtained mathematical models make it possible to predict the yield of corn at a high level of reliability depending on the indicators of the main climate-forming factors in June, that is, even before the flowering of the plants (before the stage of ВВСН 61).

Opis:: The paper summarises the results of the comprehensive scientific research carried out in the form of a two-factor stationary experiment (5 primary tillage systems × 3 fertilization systems) with rotation (2016–2020) of cereal crops (winter wheat – grain maize – spring barley – soybean) in grey forest fine sand and light loam soil. The effectiveness of the tested agricultural production method has been proven by the amplitudes of the actual cropping capacities: winter wheat – 2.80–5.00 t∙ha–1; grain maize – 4.16–8.89 t∙ha–1; spring barley – 1.78–4.45 t∙ha–1; soybean – 1.02–3.17 t∙ha–1. The rehabilitation of the physical, agrochemical and biological status of the edatope and the consolidation of the physiological processes in the grain cenoses achieved by the systemic approach to the soil tillage and fertilisation have provided for an increase in the natural biological potential of the plough land by a factor of 1.3–1.8 (from 2.96 to 5.21 t∙ha–1 of grain units, units for the equivalent measuring of different plant cultivation products). Factographic justification has been provided for the environmental, technological and technical-and-economic feasibility of implementing agronomic technologies based on the adaptive combination of mouldboard and non-mouldboard tillage (to a depth of 6–45 cm) and organic and mineral fertilization system (6.5–7.0 t∙ha–1 of plant cultivation by-products + N70P58K68). In this case, the effective fertility of an area unit in crop rotation reaches 5.72 t∙ha–1 in grain units, the production cost of raised grain – 117 €∙t–1, the earning capacity – 788 € (ha∙year) –1, the level of plant cultivation profitability – 139%. In the comparable alternatives of the system-based soil tillage (every-year ploughing, subsurface blade tillage and especially tillage with disk implements), the indices estimated above are significantly lower.

Opis:: A high degree of ploughing the soils is a destabilization factor of agrolandscapes and intensification of the erosion processes. Therefore, there arises a need to study the direction of the soil processes during the transfer of the arable land into a state of fallow. The state of microbiocenosis of a two-year-old abandoned land (fallow) was investigated using the gray forest soil in the variants of spontaneous overgrowth, sowing of grass mixtures and sowing of grass mixtures with simultaneous optimization of mineral nutrition of the phytocenosis as an example. It has been established that the least stable microbiocenosis is formed during the cultivation of the grass mixtures, which is characterized by the minimum total number of microorganisms (647.1 million CFU•g–1 of absolutely dry soil) and the minimum number of significant relations between the constituents (components) of the microbial community (98). The total number of microorganisms in the microbiocenosis of the spontaneous overgrowth variant and the legume-grass mixture exceeds that of the cereal grass mixture variant by 6.29 and 34.8%, respectively. A similar indicator for the total number of significant relations was 4.08%. Application of mineral fertilizers intensifies the process of mineralization of nitrogen compounds and slows down the consumption of the soil organic matter in the variants of sudden recovery of phytocenosis and cultivation of the legume-cereal grass mixture. The soil of the variant of the grass mixture is characterized by minimum total biological activity; it is 1.33 and 33.2% lesser than the total biological activity of the variants of spontaneous overgrowth and cultivation of the legume-grass mixture.
