“…The results obtained are confirmed by L. Gao et al (2019), found that in the soil layers of 0-10 cm and 10-20 cm, the No-till system and deep soil loosening showed a significantly higher proportion of aggregates >250 µm (macroaggregates) compared to the traditional tillage system, and the proportion of aggregates <53 µm (microaggregates) was significantly higher in the traditional system compared to No-till and deep soil loosening. The opposite results were obtained by V. Kyryliuk et al (2020), who found that minimising tillage, namely surface mouldboard tillage, worsened the soil structure compared to ploughing, especially in the 0-20 cm soil layer.…”

“…When there is insufficient moisture, it is important to prepare the soil in such a way as to ensure that the maximum possible amount of precipitation is retained. In particular, the study by V.

Modern crop production technologies depend on the intensity of soil cultivation. Traditional cultivation methods increase production costs and harm the environment. The research relevance is determined by the need to find effective and environmentally friendly alternative tillage technologies that will reduce the cost of agricultural production and have a positive impact on the environment. The research aims to determine the influence of the soil tillage system on the formation of soybean plant productivity. Research methods: long-term stationary experiment, laboratory determination of soil agrophysical properties, statistical data processing. The field research was carried out at the Agronomic Research Station, a separate subdivision of the National University of Life and Environmental Sciences of Ukraine, in a stationary experiment of the Department of Agriculture and Herbology. Soybean yields under the No-till system were found to be 22.7% higher than under the conventional system, which in absolute terms was 2.81 t/ha under the No-till system and 2.29 t/ha under the conventional system. No-till provided higher soil moisture content and the share of agronomically valuable aggregates at a higher soil density than the traditional system. In general, the efficiency of moisture use by soybean plants under the shelf tillage system was 16.0% lower compared to the no-till system. The use of the conventional tillage system on average in 2020-2022 led to a decrease in the structural structure of the 0-30 cm soil layer studied by 8-33%. The amount of agronomically valuable aggregates (0.25-10 mm) depended on the tillage system. The No-till system increased the agronomically valuable structure in the 0-10 cm soil layer by 15.5%, the 10-20 cm layer by 10.3% and the 20-30 cm layer by 9.1% compared to the conventional tillage system at the beginning of the growing season and by 4.2%, 7.3% and 4.7%, respectively, at the end of the growing season. The practical significance of the obtained research results is to determine the optimal soil cultivation system for the realisation of the genetic potential of soybean to form its stable productivity

To achieve the optimal compromise between yield and soil fertility that will help balance two important aspects of agricultural production -high crop yields and long-term soil fertility -it is necessary to understand the impact of changing row spacing on vegetable crop growth and the soil environment. The research aims to determine the adaptive properties of the "Pharaoh" variety by studying the feeding area and plant density to obtain high-quality chufa nodules in the Kyiv region. The main research methods were field studies and analysis of the variance of morphological traits and economically valuable indicators of chufa. It was found that different plant densities had an impact on the development of vegetative organs of chufa due to competition for resources during the growing season. The variety "Pharaoh" showed a high intensity of aboveground mass formation in sparse crops with a plant density in the range of 28-33 thousand plants per hectare, with the number Plant and Soil Science, ( 14)3 of leaf bundles reaching 145.2-147.4 pieces, and their average height is 50.4-52.3 centimetres. At the same time, the size of the nodules increased with a lower plant density, since with a larger feeding area, plants formed more powerful ones with thicker leaf bundles. Plants arranged in a 60×60 cm spacing (28 thousand plants/ha) formed larger nodules with the largest dimensions: 3.1 cm in length, 1.0 cm in width, and 1.2 cm in thickness. It has been substantiated that chufa of the "Pharaoh" variety was characterised by higher economic and valuable indicators under the schemes of planting 60×50 and 60×60 cm nodules. The high marketable yield of freshly harvested nodules was formed at a plant density of 28-33 thousand units/ha and amounted to 4.2-4.6 t/ha. The highest average yield of nodules after drying was obtained under the plant spacing of 60×60 and 60×50 cm, which was 3.35 and 2.99 t/ha, which was 20.9 and 7.8% higher than the control, respectively. Chufa is a promising crop in terms of food security and income generation, and precise management of plant placement will help to balance yield and soil fertility

“…The study of this process is always done by analyzing the corresponding physical models. They include either structural models, which consider the object of study at the atomic-molecular level, or structureless model, in which a solid body is considered as a continuous homogeneous medium [2,3]. Combined probabilistic-statistical models are also known, where the medium is presented in the form of a solid body consisting of randomly arranged elements with their own low-level microstructure [4,5].…”

The formation of anti-erosion procedures is based primarily on achieving an equilibrium state that affects the state of the soil or constituent rocks of the slope. In this regard, the formation of a model that can demonstrate the processes of slope destruction, which can be represented not only by soil, but also by rocks or other formations, becomes relevant. In particular, it should be relevant for urban soils and technologically transformed landscapes. The novelty of the study is determined by the fact that all possible materials that form both slopes of natural origin and technological origin are considered as objects of potential erosion activity. The authors of the article are considering the possibility of applying reclamation measures that will reduce the maximum erosion activity within not only natural, but also urban landscapes. The article developed a model for analyzing the potential of erosion activity in combination with the physical parameters of the slopes and their mechanical composition. The practical significance of the study is determined by the fact that the proposed measures and the developed model for countering erosion activity can reduce technological costs for reclamation activities and thus increase the economic and technological efficiency of the project.
