“…However, the mechanized intervention cost was higher than NT and MT management, as it required less intensity using machines. Luz et al [7] found similar results, indicating traditional soil management does not benefit to alleviate compaction when compared to a conservationist system. According to Souza et al [15], soil preparation is a high-cost operation in sugarcane renovation fields, and results from soil preparation are not maintained during the crop cycle; this occurs due to heavy machine traffic and rearrangement of soil particles in wheel interaction (Marques Filho et al) [16] and weathering agents such as rain and wind [18].…”

“…In this soil layer, the average resistances were MT (1.48 MPa), CT (1.39 MPa) and Ctrl (1.04 MPa). Luz et al [7] stated that conservationist tillage alone could not preserve the physical soil structure so other management practices are necessary. Lima et al [6] showed that lower SPR might not be related to greater volume roots in sugarcane; however, the machines' transit lines present a 35% reduction in root volume.…”

“…Sugarcane demands the most intensive machine traffic, as it is a semi-perennial crop. The intense machine traffic causes soil compaction and affects crop productivity [3][4][5][6][7][8]. Understanding soil preparation effects on crop productivity becomes important to achieve a sustainable agriculture model [9,10].…”

“…Conventional tillage promotes intensive mechanization and disturbs the internal soil structure [7], intensifying on bare soils that are more subject to compaction [16]. Therefore, conservationist tillage has grown in sugarcane crops with a view to greater plant development, lower production costs and environmental benefits.…”

The quality of sugarcane broth can be affected by soil management. In compacted soils the productivity is reduced, and the raw material is poor. This research aimed to evaluate productivity and quality of sugarcane for four soil management types: (CT) heavy harrow + light harrow; (CTI) Subsoiler + light harrow; (MT) Subsoiler and (NT) no soil movement. The variables investigated were resistance to soil penetration (SPR), the chemical raw material quality (broth) and crop yield. In crop rows, SPR did not reach severe levels up to 0.3 m for sugarcane root development. However, below this layer, MT, NT, and CTI reached SPR limiting values of 2.50, 2.35 and 1.95 MPa, respectively. In inter-crop rows, compaction was concentrated in soil surface layers (0–0.3 m). In addition, all adopted managements presented SPR above the critical value (2 MPa). The soil preparation forms qualitatively affected the sugarcane broth, showing higher fiber and protein contents in NT, MT, and CT. The PS, Brix, TRS, and Pol were not affected by soil management. Still, higher absolute values were found in the NT, indicating an increase in broth quality when applying conservation management. The highest yields were obtained by reduced tillage (MT), surpassing the lowest yield management (NT) with an increase of 10.5 Mg ha−1.

“…The results obtained through this method are immediately available, allowing the ranchers to be aware of the soil state and its vulnerability without needing extended training or specialized knowledge. Previous studies conducted in different parts of the world show the capacity of VESS to reveal differences between land use types and management options (Da Luz et al., 2022; Gutknecht et al., 2023; Mutuku et al., 2021; Purnama et al., 2022).…”

The visual evaluation of soil structure (VESS) is an affordable and easy‐to‐use method for assessing soil quality that could help in the early detection of soil quality changes in pasturelands of less developed countries where ranchers cannot afford quantitative soil studies. Here, we assessed the soil quality of three pasture areas in the Colombian Amazon region using the VESS method and tested its suitability through a correlation analysis with key physical and biochemical soil indicators of quality measured at the same study locations. Moreover, by integrating all assessed soil indicators, we determined a soil quality index (SQI) to correlate with VESS scores. A forest area was used as a reference to evaluate changes in soil indicators and soil quality due to pasture use for >25 years. Our results revealed high VESS scores, indicating poor soil quality in pasture areas and suggesting a compaction process that starts at 6.5 cm soil depth, corroborated by increases in soil bulk density, soil resistance to penetration, and reduction in soil porosity. Soil C and N contents were 35% and 33% lower in pasture than forest. This same pattern was observed in the geometric mean of the enzymatic activity. The VESS scores were significantly correlated with most of physical and biochemical soil indicators and with the overall SQI, demonstrating the ability of VESS to integrate and reflect attributes related to the essential physical, chemical, and biological functioning of soils from the Colombian Amazon region, becoming a useful tool for detecting signs of soil quality degradation in pasturelands.
