“…There are relatively accurate and robust techniques able to estimate the effect of soil random roughness on machines performances. As reported by Bögel et al [26] many measurements devices were adopted to quantify soil surface from mechanical solutions (e.g., pin meter and chain ruler), to laser scanner, cameras or acoustic instrumentations. The method commonly used for determining the degree of cloddiness resulting from tillage operations is the sieve analysis (i.e., the clods diameter is calculated splitting the sample into a given number of fractions) while as an alternative, image analysis techniques or others can be used for the determination of surface roughness [17].…”

“…Indeed, the profilometer positioning introduces errors of few centimeters. In addition, in comparison with static techniques, images taken from the UAV can maintain near-nadir looking geometry over scales of several agricultural fields [26]. The other suitable tools for determining soil roughness and cloddiness (e.g., the terrestrial laser scanning), as pointed out by Milenković et al [28,29] are not practical and suitable for the analysis of large areas.…”

The evaluation of soil tillage quality parameters, such as cloddiness and surface roughness produced by tillage tools, is based on traditional methods ranging, respectively, from manual or mechanical sieving of ground samples to handheld rulers, non-contact devices or Precision Agriculture technics, such as laser profile meters. The aim of the study was to compare traditional methods of soil roughness and cloddiness assessment (laser profile meter and manual sieving), with light drone RGB 3D imaging techniques for the evaluation of different tillage methods (ploughed, harrowed and grassed). Light drone application was able to replicate the results obtained by the traditional methods, introducing advantages in terms of time, repeatability and analysed surface while reducing the human error during the data collection on the one hand and allowing a labour-intensive field monitoring solution for digital farming on the other. Indeed, the profilometer positioning introduces errors and may lead to false reading due to limited data collection. Future work could be done in order to streamline the data processing operation and so to produce a practical application ready to use and stimulate the adoption of new evaluation indices of soil cloddiness, such as Entropy and the Angular Second Moment (ASM), which seem more suitable than the classic ones to achieved data referred to more extended surfaces.

“…To evaluate the seedbed quality, soil coverage by crop residues, surface roughness and cloddiness in the tilled layer were measured [31]. Generally, conventional primary tillage increases soil roughness and cloddiness when compared to the no-tillage system or minimum tillage [32,33]. A uniform soil surface, well-pulverized seedbed and evenly distributed residue are key to achieving perfect planting conditions [34,35].…”

Conventional seedbed preparation is based on deep ploughing followed by lighter and finer secondary tillage of the superficial layer, normally performed by machines powered by the tractor’s Power Take-Off (PTO), which prepares the seedbed in a single pass. Conservation methods are based on a wide range of interventions, such as minimum or no-tillage, by means of machines with passive action working tools which require two or more passes The aim of this study was to assess both the power-energy requirements of conventional (power harrows and rotary tillers with different working width) and conservation implements (disks harrow and combined cultivator) and the soil tillage quality parameters, with reference to the capability of preparing an optimal seedbed for wheat planting. Field tests were carried out on flat, silty-clay soil, using instrumented tractors. The test results showed significant differences among the operative performances of the two typologies of machines powered by the tractor’s PTO: the fuel consumption, the power and the energy requirements of the rotary tillers are strongly higher than power harrows. However, the results also showed a decrease of these parameters proceeding from conventional to more conservation tillage implements. The better quality of seedbed was provided by the rotary tillers.

“…Field preparation is one of the most important and expensive operations in crop production. Soil quality after tillage is mainly influenced by soil condition, soil type, and tillage operation parameters including implements, forward speed, depth, and tools (Bögel et al., 2016). Soil factors like clod size and clod distribution are influenced by tillage operations.…”

“…Therefore, using a combined tillage implement and reducing the number of passes is gaining popularity due to its positive effects on time, efficiency, and costs. Tillage tools are often designed to minimize the draft force and power requirements (Bögel et al., 2016). Various combinations of machinery or implements with rotary-powered tillage have been developed and have been found to be more energy efficient than similar single, passive tillage tools when they were tested under actual field conditions (Shinners et al., 1993).…”

Reducing energy use in soil preparation has become increasingly important since it is a major cost in planting. Experiments were conducted with a combined tillage implement consisting of a subsoiler and a rotary harrow to reduce the cost due to step reduction in soil preparation. Three tillage operations, two forward speeds, and two rotational rotor speeds were determined as input factors in this study. Soil clod size, performance parameters, and the specific energy requirements of a combined tillage implement were investigated. The field experiments were using two different soil conditions. Increasing the rotor speed from 299 to 526 rpm decreased the mean soil clod diameter at a depth of 0–200 mm from 22.98 to 19.83 mm and from 31.77 to 26.57 mm for fields 1 and 2, respectively. The specific energy requirement was affected significantly by rotor speed and tillage operation. The specific energy requirements for the combined tillage implement with an on-frame pivot joint and an on-pivotable-shank joint were less by 10.4 and 21.1% and by 18.4 and 24.7%, for fields 1 and 2, respectively, compared to the total power requirement for the separate use of a subsoiler and a rotary harrow.
