The impact of technologies for the development and use of virgin, fallow lands on agroecological stability and soil fertility

Relevance. The research was carried out in order to analyze the impact of technologies for the development of virgin and fallow lands on erosion processes in the steppe zone in the 60s and modern conditions.Methods. The analysis of approaches to the prevention of soil degradation and desertification of the territory is carried out based on materials obtained in the steppe zone of the Republic of Khakassia in the second half of the XX century and in modern conditions. We used the results of the application of technologies for the development of virgin and fallow lands of Tselinnoye LLC in different periods. Information about dust storms was taken from data from the Bey and Shire weather stations. In 1954–1960 when plowing the chernozem of the southern virgin lands, technology was used using plows, huskers and other tillage tools. The lack of adapted ways of developing and using new lands has led to an outbreak of wind erosion of soils over large areas, including in the south-east of the country.Results. The dump system of soil treatment during the mass development of virgin and fallow lands in the 60s, without taking into account soil, climatic and other conditions, led to a strong development of wind erosion. The number of days with dust storms in Khakassia reached up to 4.8–11.6 per year. In modern conditions, the removal of highly ventilated soils from arable lands and the use of strip placement of crops and minimal tillage on the rest of the arable land contribute to increasing the erosion resistance of agricultural landscapes. The use of the Tornado 500 herbicide in August during the development of the deposit reduces the erodibility by 2.5 times, compared with the technology with its introduction in early summer.

Combining a field experiment and literature to model the regrowth probability of perennial storage organs fragmented by tillage: Case study of Cirsium arvense (L.) Scop

Management of perennial weeds has become increasingly difficult with the reduction of herbicide use. Creeping perennials accumulate reserves in specialized belowground organs from which they regenerate new plants after a disturbance. Through tool selection, tillage operations could be optimized to reduce perennial-weed reserves and limit regeneration. In the present study, the effect of five tools on the fragmentation of the creeping roots of Cirsium arvense (L.) Scop. (Canada thistle), a major perennial weed in arable crops, were analysed. A field trial was set up to measure the lengths of the root fragments left after tillage. Five tools were tested: mouldboard ploughing, rotary harrow, disc harrow, rigid-tine cultivator and goose-foot cultivator. Fragment-length distribution varied according to the tool: rotary harrow left the smallest (3.7 cm on average) and least variable fragment lengths, mouldboard ploughing the longest (12.7 cm) and most variable ones. The other tools produced intermediate-sized fragments (8–10 cm). Based on these results and literature, a model was proposed to predict perennial-weed regeneration probability from storage-organ fragments after one tillage run. The effects of six factors, which were agronomic (tillage tool), environmental (soil conditions and temperature) and biological (storage-organ fragment diameter, maximal belowground-shoot length and pre-tillage storage-organ distribution), were tested through a sensitivity analysis. According to the model, the probability of fragment regeneration success is lower for the rotary harrow than for the mouldboard plough. The most important drivers of fragment regeneration success were the biological traits: fragment diameter and maximal belowground-shoot length per unit fragment biomass. The present model should be complemented to predict the effect of tillage on perennial-weed regrowth and help improving non-chemical weed-management strategies. To achieve this, further research is needed on plant regrowth potential from storage organs and their architecture in the soil.

Performance Evaluation of Biomimetic-Designed Rotary Blades for Straw Incorporation in an Intensive Tillage System

A rotary tiller is a common tillage tool for straw incorporation in an intensive tillage system. However, rotary tillage for seedbed preparation in dense-straw mulching conditions experiences high torque and poor performance of straw incorporation. Nowadays, a great deal of studies have been focused on mimicking the morphological features of low-resistance animals to improve the performance of soil-engaging tools. Accordingly, the present study investigated the performance of three C-type rotary blades (i.e., conventional, serrated, and biomimetic) under three straw lengths (50, 100, and 150 mm) for incorporation of straw into the field using an in situ field tillage testing bench. Compared to the conventional and serrated blades, the biomimetic blade had lower straw displacement (decreased by an average of 50 mm and 7 mm, respectively), higher straw burying rate (increased by an average of 5.2% and 7.8%, respectively), better straw distribution (decreased by an average of 9.1% and 10.4% on the coefficient of variation, respectively), as well as lower torque and power (decreased by an average of 3.3 N·m and 4.4 N·m, respectively) under all straw lengths. The improved performance of the biomimetic blade could be attributed to the fact that its typical teeth configuration was designed by mimicking the smooth arc of the mole-rat’s claw. These results demonstrated that the biomimetic-designed blade could be a better option for incorporating dense straw into the field conditions.

Substantiating the structural and technological parameters of tillage rotary X-like working bodies

The object of this study is the process of grinding and crumbling the surface layer of the soil with turf of winter crops by X-shaped working bodies. It has been established that the use of a grinding group based on X-shaped rotary working bodies as part of combined tillage tools makes it possible to preliminary loosen the surface layer of heavy soils (overdried or overmoistened). It was established that the optimal values of the parameters of the section of the X-shaped rotary working bodies for the quality of loosening the soil in a layer of 0–10 cm at a depth of cultivation of 14±2 cm depend on the speed of the unit. Thus, at a speed of movement of the unit of 2 m/s, the optimal value of the diameter of the rotor blade is 335.9 mm, the distance between the axes of the rotor batteries is 316.4 mm, and the distance between the rotor blades in the battery is 195.6 mm. At a unit movement speed of 2.5 m/s, the optimal values of these parameters are 331.2, 325.7, and 211.3 mm, respectively, and at a unit movement speed of 3 m/s – 330.1, 346.8, and 106.1 mm. It was also established that the stability of the movement of the X-shaped working bodies according to the root mean square deviation of the working depth increases with the increase in the speed of the unit. Thus, at a unit movement speed of 2.5 m/s, the root mean square deviation of the soil tillage depth is 1.21 cm, at a unit movement speed of 3 m/s – 1.07 cm, and at a unit movement speed of 3.5 m/s – 0 .63 cm. It was also established that the stability of the movement of the working bodies according to the depth of cultivation decreases with an increase in the speed of movement of the unit. Thus, at a movement speed of the unit of 2.5 m/s, the average soil tillage depth is set at the level of 13.1 cm, at a movement speed of the unit of 3 m/s – 12.6 cm, and at a movement speed of the unit of 3.5 m/s – at the level of 11.9 cm.

Stress Evaluation Using Finite Elements in a Manual Agricultural Tool

This study addresses the imperative need for efficient hand-held agricultural tools, particularly in challenging contexts like hillside agriculture, by focusing on the redesign and evaluation of a manual tillage tool. The objective is to comprehensively assess the stress and fatigue life of a redesigned tool, considering different manufacturing materials such as steels (AISI/SAE 4140, 4130, 1060), A356 aluminum, and nodular cast irons. Employing finite element method simulations and the Von Mises equation, this research confirms an optimal performance within elastic limits for all materials, mitigating the risks of plastic deformation or breakage during normal operation, with Von Mises stresses ranging from 8.39 to 16.30 MPa. All the tools yielded optimal results, meeting the critical requirements for soil penetration resistance, reporting no fatigue failures, and exhibiting useful life values over 1.75 x 1013 years. In terms of ergonomics, A356 aluminum stands out, as it is less heavy and implies a lower effort by the operator, promoting efficient tillage without compromising comfort. This research provides nuanced insights for the design of agricultural tools, emphasizing the harmonious balance between efficiency, longevity, and operator comfort in sustainable practices.

Discrete element modelling of the effect of disc angle and tilt angle on residue incorporation resulting from a concave disc

Understanding crop residue behaviour during tillage is critical for improving performance of tillage tools for conservation agriculture. A laboratory experiment was conducted using a concave disc to incorporate corn residue into sandy loam soil. Dynamic attributes, including soil cutting forces and residue incorporation, were measured under different lengths (75, 125, and 200 mm) of corn residue at constant disc and tilt angles. A residue-disc-soil interaction model was developed using discrete element method (DEM). Model parameters were calibrated and validated using experimental data. The validated model was used to predict the dynamic attributes at different disc and tilt angles. Experimental results demonstrated a general increasing trend in draft force (FD) and residue incorporation rate (RI), as the corn residue length increased. The two calibrated model parameters, stiffness of soil particle and stiffness of soil-residue interface were 1.15 × 106 and 13.5 N/m respectively. The validated model had an average relative error of 9.0 % and 18.2 % for predicting RI and FD respectively, as compared with the measurements. Within the angle range of 10° to 30°, the FD and RI decreased as the tilt angle (α) increased, whereas increased as the disc angle (β) increased. The effects of β were more pronounced than those of α. The optimal angles were α = 20°, β = 25° which resulted in a minimum FD and a maximum RI. The results provided new insight into residue-disc-soil dynamics and could be used to guide the selection of disc operating parameters.

Technology and technical means for the implementation of reproduction methods for soil fertility

Soil fertility is determined by the presence of humus as the main part of organic matter. The extended reproduction of soil fertility is ensured by the introduction of organic and mineral fertilizers, the cultivation of sidereal crops and the decomposition of plant residues. (Research purpose) The research purpose is developing the technologies and means of mechanization for extended reproduction of fertility. (Materials and methods) For the joint application of liquid organic fertilizers and the cultivation of siderates, a unit has been developed that implements a hose technology for transporting liquid organic fertilizers. Fertilizers are fed through pressure hose lines to the working parts deep into the soil layer. The combined unit consists of a tractor K-744 Kirovets and an adapter for deep tillage with liquid fertilizers, as well as a seeder for small-seeded crops. To level the surface of the field after the passage of the unit and the sealing of the sown seeds of the sideral culture, the unit is equipped with a tooth roller. (Results and discussion) Formulas for determining the critical processing depth are given, the power calculation of the unit is performed. The design of the tillage tool allows to install flat-cutting working parts with a grip of 0.80 meters and slits with a grip of 0.45 meters. Tests of the combined unit were carried out. The depth of tillage was 36±1 centimeters, the seeding rate of the sideral crop (oilseed radish) was 25 kilograms per hectare, the operating speed range of the unit was from 0.4 to 0.8 meters per second. (Conclusions) The uniformity of the subsurface distribution of organic fertilizers was 90-95 percent. The specific energy intensity of the technological process of the combined unit based on the K-744 tractor for intra-soil fertilization is 40-65 kilowatt hours per hectare (excluding the capacity for pumping fertilizers). Energy consumption depends on the depth of cultivation and resistivity of the soil. The proposed method allows preventing water and wind erosion of the soil, improving its agronomically valuable properties. Reducing the pesticide load on the soil and its microflora contributes to the transition to a model of sustainable agroecosystems, improving and improving crop quality. The proposed technology provides extended reproduction of soil fertility.

Substantiation of the Use of a Flexible Chain-Type Subsoiler for Improving the Agrotechnological Properties of Soil

Technogenic influence on agricultural soils leads to the transformation of their morphological features, significantly worsens their agrochemical, physical, mechanical and agrotechnological properties, prevents the optimal use of potential soil fertility and, as a result, leads to a decrease in crop yield. Mechanical soil decompaction when using various types of subsoilers, including the flexible chain-type working body (the chain), is used to prevent the negative consequences of technogenic influence. According to the results of the analytical calculations, the proportionality factor of the chain length, which determines the ratio of the width of the plow grip to the chain length of a flexible subsoiler, was established. The specified coefficient is proportional and equals 2.4. The use of the specified coefficient allows us, at the stage of the development of the design and technological documentation, to determine the main design parameter of the flexible subsoiler, which is the length of the used chain depending on the width of the plow grip. The surface of the field cultivated with the experimental tillage tool meets the requirements for sowing the agricultural crops without performing additional technological operations.

Comparison of microstructure, mechanical, and electrochemical performance of laser-deposited FeCrV15 alloy at varying powder feed rates

In the realm of surface modification, repair, and reinforcement of components exposed to challenging operational conditions, such as tillage tools, laser cladding stands out as an innovative manufacturing technique. Employing this additive manufacturing approach, a functionally graded material with outstanding strength and properties is incorporated to enhance the desired attributes of the base material. This comparative investigation scrutinized and assessed the microstructural characteristics, hardness, wear resistance, and corrosion behavior of high carbon ferrochrome FeCrV15 coatings fabricated at two distinct powder feed rates, namely 5 and 6 g/min, respectively. The analysis delved into how the resultant coatings' molten bead deposition, microstructural evolution, hardness, wear resistance, and corrosion resistance were influenced by the powder feed rate. Evaluation of hardness was conducted using a Vickers microhardness testing apparatus, while phase identification was accomplished utilizing an X-ray diffractometer. The morphologies of the microstructures were scrutinized employing optical microscopy and scanning electron microscopy coupled with energy dispersive spectroscopy (SEM/EDS). Furthermore, the corrosion response of the deposits in a soil–water environment was probed utilizing an Autolab potentiostat. A comprehensive assessment of the coatings' sliding wear performance was undertaken using an Anton Paar Tribometer. The findings of the study reveal that an escalation in the powder feed rate engenders heightened grain refinement within the microstructure, yielding a defect-free sample and augmenting the wear performance (with a wear rate of 2.42 × 10–6 mm3/N/m for sample B, surpassing 2.39 × 10–5 mm3/N/m for sample A and outstripping 1.72 × 10–3 mm3/N/m for the steel substrate). Additionally, the corrosion resistance is enhanced (with a corrosion rate of 0.0032 mm/yr for sample B, surpassing 0.0036 mm/yr for sample A, which, in turn, exceeds 0.1168 mm/yr for the steel substrate) in the case of sample B.

ANÁLISIS NUMÉRICO Y EXPERIMENTAL DEL DESGASTE ABRASIVO DE DOS ACEROS UTILIZADOS EN APEROS DE LABRANZA

This study combines computer simulation using the Discrete Element Method (DEM) with field experiments to assess the resistance to abrasive wear of AISI 1010 and AISI C1064 steels in tillage tools. It was found that the wear on AISI 1010 was over 50% higher than on AISI C1064. The DEM model accurately predicted wear (e=0.005g, R^2=99.8%), regardless of operational conditions and steel characteristics. The mean absolute errors of the simulation compared to field tests were 0.01937 g for AISI C1064 and 0.08619 g for AISI 1010.

Investigation of Furrow Formation by Rotary Tillage Tools with an Active Drive

Power driven rotary tillage tools are widely used in agriculture. However, the process of furrow formation by these tillage tools remains insufficiently studied. (Research purpose) To study the process of furrow formation by the actuating elements of rotary working bodies with an active drive. (Materials and methods) The experiments were carried out on a laboratory setup in a soil bin filled with sandy soil. The attack angle of the working elements ranged from 30 to 90 degrees, and the kinematic parameter varied from 0.8 to 2.2. The actuating element of the investigated rotary tillage tools was made in both circular and elliptical blade forms with the least curvature line (the major semi-axis of the ellipse). The actuating element with an elliptical blade has the ability to adjust the angle of inclination relative to the axis of rotation of the of the tillage tool. (Results and discussion) Rotary tillage tools with a circular blade form a furrow parallel to the travel direction. It has been established that an increase in the attack angle of the tillage tool from 30 to 90 degrees results in a twofold increase in the width of the furrow. The actuating element, made along the elliptical line of the blade, forms a furrow having the shape of a parallelogram when viewed from above. At a small angle of attack, this actuating element forms a short, narrow furrow deviating from the unit’s travel direction within the boundaries of the furrow width of the rotary tillage tool. (Conclusions) The results obtained make it possible to choose the parameters for the studied rotary tillage tools, which will ensure the formation of optimal furrows. This will increase the evenness of the furrow bottom and the degree of weed destruction, i.e. improved soil quality.

Mechanical, wear and corrosion behaviours of laser additive manufactured iron-based heterogeneous composite coatings for tillage tools

Steel is commonly used in engineering components, and it has a high tendency to wear and corrosion attacks when exposed to unfavourable working conditions. The use of chromium-vanadium-iron-rich carbide reinforced iron-based hard facings has become more important in improving the corrosion and wear resistance of such steel subjected to abrasive and impact conditions. In this study, the chromium-vanadium-iron carbide reinforced coatings were developed using in-situ by depositing FeCrV15+Cr powder through laser cladding on carbon steel. The influence of the reinforcement on the microstructure of the coating in relation to its laser processing condition and extra chromium addition was investigated. Furthermore, the effect of the coating's reinforcement on the hardness, microstructures, anti-corrosion, and anti-wear properties of the carbon steel used in tillage and mining operations was investigated. The result is a defect free deposits with a solid metallurgical attachment to the substrate and improved microhardness. FeCrV15 deposits had a wear-resistant (with a wear rate of 2.42 × 10−6 mm3/N/m) and anti-corrosion capability (with a corrosion rate of 0.001869 mm/yr) that were several folds higher than the steel substrate (with wear rate of 1.72 × 10−3 mm3/N/m and corrosion rate of 0.1168 mm/yr). The general grain refinement of the FeCrV15 deposits was richly enhanced in the iron base matrix. This resulted in outstanding wear and corrosion resistance attributed to the better production of VC–Cr3C2–Cr7C3 particles and better grain refinement of the microstructural formation.

Agrotechnical performance indicators of the asymmetric working body of a fallow cultivator

BACKGROUND: Obtaining sustainable and high-quality harvest is important for the production of agricultural products. It is known that up to 40-45% of all energy costs are spent on preparing the soil for sowing when cultivating agricultural crops. Surface-fallow tillage is a subtle technological process, it influences on normal distribution of the seed material in depth and, as a consequence, the further uniformity of seedlings. To ensure the process flow of pre-sowing preparation of the soil for sowing, a new asymmetric working body for a fallow cultivator was developed in the Donskoy Agrarian Scientific Center, the structural subdivision of the SKNIIMESKh, Zernograd. There is a task to conduct a comparative analysis of operation of the new working body with V-shaped sweeps when preparing the soil for sowing. AIM: Conducting a comparative analysis of operation of a serial V-shaped sweep with the new proposed asymmetric working body of a fallow cultivator by field research in the fields of the Donskoy ANC. METHODS: The research in the fields of Donskoy ANC was conducted according to the GOST 33687-2015 “Machines and tools for surface tillage” regional standard. Well-known statistical extrapolation methods implemented in the Microsoft Excel environment were used for data processing. RESULTS: The optimal operating parameters of the new proposed asymmetric working body have been determined in comparison with the serial working body of a fallow cultivator. CONCLUSIONS: According to the conducted laboratory and field studies, the parameters and operating modes of the new asymmetric working body were obtained.

Vertical tillage effects on crop production and pest management in Pennsylvania

AbstractWithin the last four decades, widespread transition to no‐till corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] production in Pennsylvania has improved soil conservation and soil quality but can result in residue and pest management challenges. To effectively manage residue in no‐till cropping systems, some growers have adopted vertical tillage, a residue management practice characterized by cutting and incorporating crop residue within the top 5–10 cm of soil. Despite few studies documenting effects on crop production and soil conservation, vertical tillage has become widespread. Replicated on‐farm trials were conducted over a 2‐year period in 2021–2022 to improve grower and consultant decision‐making regarding the role of vertical tillage relative to continuous no‐till on southeast Pennsylvania farms located within the environmentally sensitive Chesapeake Bay Watershed. We assessed the effects of vertical tillage on corn residue cover, winter annual weed abundance, slug damage, and soybean performance in 40 paired strip trials comparing spring vertical tillage to no‐till using three different vertical tillage tools used by farmer cooperators. Vertical tillage equipment type is a driver of variation in changes to surface residue cover. Baseline surface residue cover was similar among no‐till strips, but a greater proportion (32%) of strips had mean surface residue cover levels below a 60% conservation program compliance threshold when a Kuhn‐Krause Excelerator was used. Relative to no‐till, vertical tillage resulted in a 50% reduction in winter annual weed cover, a 24% reduction in slug damage, and no significant differences in soybean stand establishment or grain yield.

Predicting the Power Requirement of Agricultural Machinery Using ANN and Regression Models and the Optimization of Parameters Using an ANN–PSO Technique

Optimizing the design and operational parameters for tillage tools is crucial for improved performance. Recently, artificial intelligence approaches, like ANN with learning capabilities, have gained attention for cost-effective and timely problem solving. Soil-bin experiments were conducted and data were used to develop ANN and regression models using gang angle, velocity ratio, soil CI, and depth as input parameters, while tractor equivalent PTO (PTOeq) power was used as an output. Both models were trained with a randomly selected 90% of the data, reserving 10% for testing purposes. In regression, models were iteratively fitted using nonlinear least-squares optimization. The ANN model utilized a multilayer feed-forward network with a backpropagation algorithm. The comparative performance of both models was evaluated in terms of R2 and mean square error (MSE). The ANN model outperformed the regression model in the training, testing, and validation phases. A well-trained ANN model was integrated with the particle-swarm optimization (PSO) technique for optimization of the operational parameters. The optimized configuration featured a 36.6° gang angle, 0.50 MPa CI, 100 mm depth, and 3.90 velocity ratio for a predicted tractor PTOeq power of 3.36 kW against an actual value of 3.45 kW. ANN–PSO predicted the optimal parameters with a variation between the predicted and the actual tractor PTOeq power within ±6.85%.

Использование жидких комплексных микроудобрений для роста и развития робинии псевдоакации и сосны крымской в засушливых условиях

The article presents data on the results of testing complex micronutrients when sowing seeds of Robinia pseudoacacia L. and Pinus nigra subsp. pallasiana (Lamb.) Holmboe. at a production nursery. Stratification provides seeds with rapid germination under optimal conditions of oxygen access and maintaining a humidity level and temperature of 10°C. Fertilizers “Volski Biochem” are able to increase the energy of germination of seeds of the studied species, increase their growth rate and contain all the necessary nutrients for plants. The highest content of trace elements is found in the preparation “Microel”. Established that the best option for planting seeds are RCL‑81 forest cassettes, which naturally and correctly distribute the root system of seedlings, increase their ability to form active root tips, provide oxygen to plants and eliminate waterlogging with improper watering. The percentage of safety for seedlings in the first and second year was almost the same. Pine seeds require de-spraying on the VSG‑01 air gravity apparatus before processing and planting. The possibility of using tools for tillage and crops is provided by an ordinary method with the location of narrow sowing lines along the tapes. Proven that the use of complex micro fertilizers allows pine and robinia seedlings to have an optimal ratio of the aboveground part and the root system, accelerated growth and development, and an even stem. The maximum growth of robinia was 71–98 cm, pine trees 10–29 cm, which fully met the standards and requirements for the cultivation of planting material of woody species. Revealed that the differentiation of robinia and pine seedlings in height begins in the second half of June, in the variant of the experiment with sowing seeds in a box, the largest gains of seedlings were observed in the third decade of June, after which there was a noticeable decrease in growth. As a result, the best growth and development indicators were observed in Crimean pine in the 1st variant of the experiment, in robinia pseudoacia in the 1st and 2nd variants. The growth rates of two-year-old seedlings of the studied species are identical to those of annual seedlings

Computational Approach to Geometric Modeling of Plow Bodies

In this article, a detailed analysis of modern research and publications on the selected subject was carried out related to the computer-variant geometric modeling of the working surfaces of the plow blades. Based on this, a new method of proper design was proposed. The performed scientific investigations aimed to create a flexible, productive, and universal approach for the automated shaping of tillage tools. The accentuated effectiveness of geometric modeling was achieved using a developed special mathematical apparatus adapted for use in the environment of current computer information systems of an engineering profile. The implementation was based on such parametric lines as heterogeneous rational B-splines, which are acceptable in automated design systems. The specified geometric models were characterized by the coverage of a sufficiently large range of plow heads. The indicated means of forming could conveniently adapt to the changing conditions of designing tillage tools suggested by theoretical calculations and practical experiments. The given facts contributed to the multifaceted clarification of the specified information. They also ensured the appropriate integration and the possibility of determining the most rational options among the studied varieties of plow dumps. Simultaneously, the most common group of dumps with cylindrical and other plow working surfaces was considered. The significant role of geometric models for qualitative coordination and the effective combination of many other models (e.g., strength, manufacturing technology, and operation conditions) was emphasized. This was aimed at comprehensive optimization throughout their life cycle, in this case of plows. The proper solution to the presented problems contributed to a successful solution to the actual scientific and applied problem of improving the quality of machinery.

Modernized tilling unit

It is noted in the work that the increase in the efficiency of agricultural production in our time is not possible without reducing energy costs. At the same time, the technical means of mechanization of the tillage process have a high material consumption, which leads to an increase in energy consumption, indicating energy and environmental problems. In an effort to improve the quality of soil preparation, expand the functionality of the unit, reduce energy consumption, simplify design and import substitution, the use of known tillage tools has been studied and analyzed. As a result, on the basis of exploratory research, a modernized tillage unit has been developed. The new elements of which are that a chopper module is mounted behind the disk module, consisting of staggered chopper rollers in two rows. The modernized tillage unit considered in the article, developed on the basis of KubGAU, improves the quality indicators of soil cultivation, on which the effective accumulation and consumption of soil moisture depends, reduces energy consumption by increasing the functionality of the unit.

Comparative Agrotechnological Assessment of Disk Tillage Tools

Currently, in Krasnodar Territory, disk tools are most often used for surface tillage. The efficiency of using disk tools primarily depends on the design and technological layout of their working bodies, soil and climatic conditions of operation and the number of working passages through the field. The article presents an agrotechnical assessment of disk tillage tools based on open data from machine testing stations of the Russian Federation. Based on the results obtained, the main agrotechnical performance parameters that do not meet generally accepted requirements are determined.
