“…Moreover, the harvested grass is often transported along the GBZs. The lower infiltration rates in fields close to the GBZs, as compared to fields 10–50 m from the GBZ, can also be linked to soil compaction, since this land is where the farmers turn the farm machinery (Obour et al 2018 ).…”

Phosphorus retention and bank erosion was investigated in two types of buffer zones in cereal fields in Norway: zones used for grass production and zones with natural vegetation. Farmers’ views on the two types of buffer zones were collected through questionnaires and in-depth interviews. Our results indicate that the grassed buffer zones had higher levels of plant-available phosphorus and lower infiltration rates than the natural ones. Bank erosion was higher in zones with grass production than those with trees. Interviews with farmers revealed diverging opinions on the zones. Most farmers were sceptical to natural vegetation with trees, whereas farmers who had already planted trees in the riparian zones were generally satisfied. Buffer zones can have many different functions, and we conclude that a holistic approach is needed when assessing the usefulness of this measure, taking into account water quality, biodiversity and the production of food, fodder and biomass.

“…Multivariate statistical techniques were used in this study since they are pointed out as an important tool in the study of soil physical quality indicators (Oliveira et al, 2015), soil management analysis (Mantovanelli et al, 2015;Soares et al, 2016), and crop productivity as a function of soil physical quality (Obour et al, 2018). In fact, they are efficient in distinguishing conventional management with and without additional compaction, demonstrating the simultaneous effect of mechanized tillage on soil physical attributes (Figures 2 and 3).…”

With agricultural expansion in Amazonian regions, studies are needed to verify the effect of mechanization on the soils of the regions. This study aimed to assess soil physical attributes under different compaction conditions induced by tractor traffic on a soil of southern Amazonas State, Brazil. Treatments consisted of three compaction levels: conventional soil tillage without additional compaction (CT) and conventional soil tillage with additional compaction with four (CTc4) and eight tractor passes (CTc8). An intense increase in soil aggregate diameter was observed in the superficial soil layer (0.00-0.05 m) from four tractor passes, decreasing in the successive soil layers (0.05-0.20 m). Soil density increased up to a depth of 0.10 m. The reduced macroporosity and soil moisture on the soil surface (0.00-0.05 m) did not significantly alter soil microporosity in the different treatments. For the macroporosity, the 0.00-0.05 m layer was the most impaired, with a reduction of more than 50% for the treatments submitted to compaction (CTc4 and CTc8). The penetration resistance for the 0.00-0.05 m layer was increased by more than 150% between the treatment without compaction (CT = 0.88 MPa) and compaction (CTc4 = 2.25 MPa; CTc8 = 2.50 MPa). These results show a greater caution in the agricultural machinery management in Amazonian soils, which may be aggravated due to the intense water regime in the region.

“…The process of compaction of the soil is aggravated by numerous passes of energy-saturated tractors across the field as a result of the implementation of a full cycle of agricultural cultivation technology. The authors of the studies (Obour et al, 2017;Obour et al, 2018;Silva et al, 2018) note that soil compaction depends on the timing and time of tillage operations, while soil compaction reaches the lower layers to a depth of 1 m.…”

Implementation of agricultural technologies for crop cultivation is not possible without the use of energy-saturated tractors. As a result of the passage of tractor movers, they have a negative effect on the soil, leading to its compaction and lower crop yields. The aim of the research is to determine the influence of movers of various running systems of energy-saturated tractors on the physical and mechanical properties of the soil. To assess the impact of tractor movers on the soil, mathematical dependencies were presented to determine the soil index characterizing the physical and mechanical property of the soil, which is changed as a result of the impact and its influence when assessing the complex indicator of soil impact. The results of field studies of the effects of movers of the tractors K-701 and K-744 on the soil are presented. As a result of the research, it was found that the serial single mover of an energy-saturated tractor exerts a strong effect on the soil, creating a high voltage IV International Scientific and Practical Conference "Modern S&T Equipments and Problems in Agriculture" 180 in it leading to excessive soil compaction. The use of double wheels in comparison with single wheels makes it possible to reduce the negative impact on the soil; in particular, a decrease in stresses occurring in the soil to 10.1% and a decrease in soil density along the tracks of movers to 13.8% were recorded. The results of the calculation of a comprehensive indicator of the negative impact on the soil by different tractors are presented. The proposed methodology allows optimal manning of the enterprise's vehicles providing minimal impact on the soil and crop preservation.
