“…On the other hand, the working rate of an offset disc harrow like that used by Barro et al (2022) can be even much lower, ranging from 0.12 to 0.43 ha h −1 m −1 depending on the soil and tillage depth and requires about 1.5 kN m −1 of width when working at around 6.5 cm depth. In addition, disc harrows have greater fuel consumption, about 5.5 L ha −1 or more (Choudhary et al , 2021). Similarly, power harrows, even when working very shallowly (e.g., 6 cm depth), require greater power and imply greater fuel consumption (8 L ha −1 ) at the speed of 9 km h −1 (Balsari et al , 2021).…”

Summary Cover crops and conservation soil tillage are reconsidered in cropping systems for their several agronomical and ecosystem services. In this frame, an important role is played by cover crop termination and seedbed preparation, which are crucial for a timely and successful establishment of the following cash crop. This work was aimed at testing a disc chain harrow for terminating a cover crop of hairy vetch and preparing a seedbed for soybean and defining its operational characteristics. A total of three trials were carried out to (1) compare two types of discs in two different front + rear combinations and two different working speeds (8 vs. 14 km h−1) in terms of efficacy of hairy vetch termination; (2) evaluate the seedbed preparation by the disc chain in terms of soybean establishment as a following cash crop; (3) evaluate operational characteristics (working speed, fuel consumption, absorbed power, etc.) of the disc chain at the two different speeds. Results demonstrate that the disc chain is a valid tool for cover crop termination and seedbed preparation in a conservation tillage approach. The quality of work was affected by the type of disc and the working speed. The disc chain showed good operating performance, with low mechanical pulling force, low energy requirement for traction, and low fuel consumption as compared to alternative conservation practices for cover crop termination and/or shallow soil tillage.

“…Tillage is one of the most energy-intensive operations in agriculture [31]; high amounts of energy are devoted to cutting, breaking, and possibly overturning soil layers, reducing the size of clods and rearranging soil aggregates [32]. The results of this study for the NS variant, namely the 1.2% reduction in UD (see Table 1), though not significant, support the findings of the study by Urbanovičová et al [33], who reported that biostimulants had a positive effect on UD reduction.…”

Food production sustainability is one of contemporary agriculture’s fundamental challenges. Farmers are currently facing high input prices in crop production and declining organic matter in the soil. For this reason, a field experiment was established to assess the effect of the biostimulant NeOsol (NS), the manure stabilizer Z’fix (ZF), farmyard manure (FM), and their combination in farm practice. In situ measurements provided information on the change in bulk density (BD), unit draft (UD), saturated hydraulic conductivity (SHC), and cone index (CI). Furthermore, the vegetation status was investigated via vegetation indices, and the yield and quality parameters were assessed. Management of the experimental field resulted in an overall decrease in BD over time for the treated variants compared to the control (CL). The decrease with time was also verified in the case of UD and CI at the depth zone of 10–20 cm. Variants FM (by 8.0%), FM_NS (by 7.3%), and FM_ZF_NS (by 3.8%) proved to have lower UD values than CL. An overall increase in SHC and in yield was observed over time. Concerning SHC, only FM (by 58.5%) proved different from CL. The yield of all the treated variants, i.e., NS (by 8.2%), FM (by 10.8%), FM_NS (by 14.1%), FM_ZF (by 17.8%), and FM_ZF_NS (by 20.1%), surpassed CL. Simultaneously, none of the examined treatments proved to have any adverse effect either on soil or on plant-related variables.

“…The greatest energy-consuming agricultural practice is tillage, which is used in primary production. According to Borin et al [7], tillage contributes to around 25% of the overall energy input for crop production, and 92% of this energy is currently provided by fossil fuels [8]. Several studies have extensively characterized the energy consumption of the tractor-implemented system under various operating parameters (i.e., working depth and speed), as well as various soil types and moisture levels [9][10][11][12].…”

Manufacturers are looking for innovative solutions to improve the sustainability of their products in terms of environmental, economic, and social issues. Many studies demonstrate that conservative tillage techniques can be more advantageous for the environment and farmer profits than conventional tillage techniques. However, conservative tillage tools have certain disadvantages, including challenging weed control and stagnation issues in humid conditions due to low soil porosity at depth. In this study, field tests were conducted comparing the performances of a conventional tillage technique, using a ripper and a rotary tiller, and the usage of an innovative rotary ripper (Rotoripper). The comparison was performed in terms of energy requirements, through data acquisition during tillage operations, tilled soil quality, through soil sieving and cone penetration tests, and ownership costs, through acquired field data and literature databases. The results indicate that increased porosity of the soil in the deepest layer and increased cost-effectiveness are the main advantages attainable with the use of the Rotoripper instead of conventional tillage equipment. However, because of the low soil segregation level achieved with the Rotoripper, additional tillage activities are required before planting.
