“…In all three study years, the CT processing showed lower compaction compared to the DH and CH processing systems, which is consistent with the results of [31], conducted at similar depths. The deep processing of SS, performed using a submersible with seven working bodies at a working depth of 50 cm, resulted in the lowest penetrometer resistances in all three study years, which is consistent with the results of [28,29]. Resistance in the 2nd year of maize planting was statistically significantly affected by tractor tire pressure at sowing in the first two measurements (as follows F = 6.67; F = 4.26; F = 2.48 n.s.…”

“…In both measurements of the third year of research, compaction under the influence of tire pressure was 13.2% higher than at pressure p 1 in the first measurement and 20% higher in the second measurement, which corresponds to the results of the research of Parkhomenko et al (2019) [29]. Soil resistances in the 3rd year of observation were statistically significantly affected by depth measurement in both measurements (as follows F = 68.37; F = 35.51).…”

“…The authors of [28,29] found that using a subexcavator with a greater tillage depth reduced soil compaction while improving soil infiltration capacity. Increasing the tillage depth of the same cultivation tool when implementing basic tillage CH and SS resulted in a reduction in soil compaction.…”

Intensive agricultural practices affect soil compaction, and their indirect and direct effects on crop growth and development are an increasingly important focus of scientific research. The objective of this study was to determine the influence of different tillage systems on soil compaction and to observe the influence of tractor tire pressure on penetrometer resistance during sowing. The three-year study was conducted on the heavy pseudogley soil of Brod-Posavina County in the Republic of Croatia. During the research, crops were observed in the following cropping sequence: soybean (Glycine max L.) in the first year, maize (Zea mays L.) in the second year and winter wheat (Triticum aestivum L.) in the third year. The tillage systems as the main study factor were conventional tillage (CT) plowing to a depth of 35 cm, disc tillage (DH) to a depth of 15 cm, loosening (CH) to a depth of 30 cm, and undermining (SS) to a depth of 50 cm. The following pressures were used as a subfactor of this study, namely the pressure of the front and rear tires of the tractor during sowing: p1 (front 1.0 bar/rear 0.8 bar), p2 (front 2.0 bar/rear 1.6 bar), and p3 (front 3.0 bar/rear 2.4 bar). The tillage systems applied resulted in different soil compaction, thus the deepest tillage SS had the lowest resistance and the DH tillage had the highest resistance in all three experimental years. Penetrometer measurements showed the influence of tire pressure p1 on reducing compaction as early as the first year in 2017, while in the last year of research in 2019, tractor tire pressure p3 during sowing contributed to a significant increase in soil compaction.

“…The mechanisation of agriculture at the beginning of the twentieth century was a real game-changer when it came to sustaining food production and increasing the yield potential of arable land. However, decades of monoculture and uniform practices contributed greatly to an increased negative impact on the environment [1,2]. This led researchers from different fields to focus their efforts on trying to find efficient solutions that make agricultural practices more sustainable and environmentally friendly [3].…”

The ageing population, climate change, and labour shortages in the agricultural sector are driving the need to reevaluate current farming practices. To address these challenges, the deployment of robot systems can help reduce environmental footprints and increase productivity. However, convincing farmers to adopt new technologies poses difficulties, considering economic viability and ease of use. In this paper, we introduce a management system based on the Robot Operating System (ROS) that integrates heterogeneous vehicles (conventional tractors and mobile robots). The goal of the proposed work is to ease the adoption of mobile robots in an agricultural context by providing to the farmer the initial tools needed to include them alongside the conventional machinery. We provide a comprehensive overview of the system’s architecture, the control laws implemented for fleet navigation within the field, the development of a user-friendly Graphical User Interface, and the charging infrastructure for the deployed vehicles. Additionally, field tests are conducted to demonstrate the effectiveness of the proposed framework.

“…This leads to the operator's increased fatigue and a decrease in the productivity of up to 10-15% [8]. The main reason for the slip of the plowing unit from the straight-line direction is the impact of the plow on the tractor [9][10]. The composite surface of the moldboard plow leads to a deviation of the normal resistance force P by a certain angle β=15 o …25 o relative to the longitudinal axis of the tractor [11].…”

The discrepancy between the plow width and the tractor width leads to the asymmetry of plowing units. The geometry of the plowshare surface of the moldboard plow contributes to the generation of lateral forces on the working tool. All this leads to the imbalance of the tool and the deviation of the tractor from straight-line movement during plowing. To maintain straight-line movement, the driver has to adjust the machine every 5-10 meters, which is highly tiresome. To study the causes of lateral slips of the plowing unit, we constructed a mathematical model, which consists of the equations of controlled movement and equations of the tractor's uncontrolled shear under the action of external forces from the plow. The description of the force interaction of the drive with the ground is based on the mathematical theory of friction, taking into account anisotropy and elastic properties in contact. Based on the passive shear model, we constructed a hodograph diagram of the maximum tractor shear force from the side of the working tool. We found that the shear force reaches its maximum friction value only in the case of a translational shear, when its line of action passes through the tractor's center of gravity. In all other cases, the shift (slip) of the tractor is caused by a lower force. We formulated the features and assumptions of the model as applied to caterpillar and wheeled tractors. As a result, we found that, regardless of the direction of the lateral displacement of the plow's traction resistance, the tractor is slipped towards the plowed field. The result of the numerical experiment showed that the main reason for the slip of the wheeled plowing unit is the difference in soils along the sides of the tractor but not the deviation of the plow traction resistance.
