“…In compatible with our findings, Hargreaves et al. () stated that large, angular aggregates in the top 0–10 cm of the trampled soil are the signs of compaction. Non‐porous angular structures in subsurface layers were scored as 3.0 by Castioni et al.…”

“…The compacted subsurface layers in RT and NT systems were also characterized by dense large angular and hard to break clods ( Figure 5). In compatible with our findings, Hargreaves et al (2019) stated that large, angular aggregates in the top 0-10 cm of the trampled soil are the signs of compaction.

“…Therefore, the visual evaluation of soil structure (VESS) method which does not require long‐term training and expensive equipment (Johannes, Weisskopf, Schulin, & Boivin, ) has been preferred to determine structural quality of soils under different management and cultivation practices (Guimarães et al., ; Leopizzi et al., ; Moncada et al., ). The VESS is a reliable tool for identifying the compaction in surface horizons and helps in the management of compacted soils which may cause yield loss (Hargreaves et al., ). Despite the aforementioned merits of the VESS method, the major drawback is the lack of information on features of soil layers below the 25 cm depth of soil surface where severe compaction might occur in conventionally tilled soils.…”

Current agricultural practices and their impacts on the sustainability of crop production can be evaluated by simple and reliable soil structure assessment tools. The study was conducted to determine the effects of long‐term (2006–2017) tillage systems on structural quality of a clayey soil using the visual evaluation of soil structure (VESS) and classical field and laboratory measurements. A field experiment with seven tillage systems, representing both traditional and conservation tillage methods, was conducted on a clayey soil in the Cukurova region, Turkey. Soil samples from 0–10, 10–20 and 20–25 cm depths were analysed for mean weight diameter (MWD), porosity and organic carbon. Penetration resistance (PR) was determined in each treatment plot. The VESS scores (<2) of upper 0–5 cm indicated a good structural quality for all tillage systems. The VESS scores were positively related to PR and MWD and negatively to macroporosity (MaP) and total porosity. In reduced and no‐till systems, poorer soil structures were observed in subsurface layers where firm platy and angular blocky structures were defined. Mean VESS score (3.29) in 20–25 cm depth where PR was 3.01 MPa under no‐till indicated a deterioration of soil structural quality; thus, immediate physical interventions would be needed. Lower VESS scores and PR values under strategic tillage which was created by ploughing half of no‐till plots in November 2015 indicated successful correction of compaction caused by long‐term no‐till. The results suggest that the VESS approach is sensitive and useful in distinguishing compacted layers within the topsoil.

“…Agricultural machinery fieldwork will cause certain state (S) changes, such as soil compaction, which produces varying degrees of I [22]. These I factors include a reduction in the drought resistance of the cropland and the destruction of the soil structure [23]. The CLQ could be regulated in the agricultural production process by improving tillage methods, optimizing planting patterns and promoting soil and water conservation behaviors among farmers [24], which are referred to as the…”

Quantitative evaluations of the cultivated-layer quality (CLQ)of sloping farmland are important for the effectively improving and rationally utilizing of the cultivated layers. Using a red soil watershed as the research object, we quantitatively analysed the relationship among factors influencing the CLQ using structural equation modeling based on the DPSIR framework (A framework for describing the interactions between society and environment developed by the European Environmental Agency) to describe the CLQ evolution process. We identified the key indicators of the driving factors (D) during cultivated-layer degradation and critical environmental pressure (P) to construct a reasonable cultivatedlayer (RCL) by principal component analysis (PCA). We defined the main CLQ diagnostic indicator set to assess the CLQ by factor analysis and analysed the reasonable measures to improve the CLQ. The results show quantified direct or reverse effects among D, P, state performance (S), problem impacts (I) and response strategy (R). The contribution rates of D and P were affected by the comprehensive effects of natural and human factors or human factors along. The CLQ diagnostic indicator set included 7 soil indicators and sub-soiling is the main adjusted measure for cultivated-layer recovery. These results could provide important technological paths for objectively understanding the causes drivers of the degradation and improving the CLQ for red soil sloping farmland.

“…Soil physical quality properties such as bulk density, porosity, water retention capacity, and penetration resistance, indirectly affect crop development and yield (Hargreaves et al, 2019). In the no-tillage system, restrictions related to compaction may be greater (Peixoto et al, 2019), since soil mobilization is restricted to the sowing line.…”

Cultivated soils, when submitted to agricultural practices, tend to compact due to the pressure exerted by agricultural machines and implements, a process that compromises soil quality and system sustainability. Specific properties of each soil, such as particle size and organic matter content, interfere with the process and degree of compaction and, consequently, plant growth. This study aimed to analyze the effect of different degrees of compaction (DC) on soil physical properties and black oat (Avena strigosa Schreb) growth. For this purpose, four soils were collected: Latossolo Vermelho distrófico retrático (Ferralsol LV CN), Cambissolo Húmico alumínico típico (Cambisol CH LG), Nitossolo Bruno distrófico típico (Nitisol NB PA), and Nitossolo Bruno distrófico húmico (Nitisol NB SJ). They were submitted to five degrees of compaction (bulk densities corresponding to 80, 85, 90, 95, and 100 % DC), defined by their relation to the maximum density obtained by the Normal Proctor Test. For each DC, porosity, soil water retention curve, penetration resistance, hydraulic conductivity, and aeration capacity were determined. In a greenhouse, the oats were cultivated in the four soils with five different degrees of compaction. The experiment was carried out in a completely randomized design, factorial scheme, and five replications. Crop measurements included the growth rate, shoot dry matter, and forage quality analysis. Soil compaction changed the physical properties of soils. In all tested soils, macroporosity and total porosity decreased, more intensely at LV CN. It had macroporosity below the critical level (0.10 m 3 m-3) from DC 85. Hydraulic conductivity also decreased in all soils, which is evidence of significant environmental degradation from DC 90 onwards. Microporosity increased in the four soils due to compaction effect, and it is one of the reasons why permanent wilting point has increased. It resulted in a problem at NB SJ , mainly because it reduced the available water volume at DC 90, 95, and 100. Penetration resistance has also increased from DC 80 to 100 at all soils, exceeding the limit of 2 MPa in DC 80 for NB SJ , DC 85 for NB PA and LV CN , and DC 95 for CH LG , representing a risk to root development. Regarding black oat crop, there was a reduction in shoot dry matter only in Cambisol and in the higher DC, fiber content keeps within a satisfactory amount, without affecting forage quality in all soils and DC, thus showing that black oat is tolerant to compaction.
