“…Despite the similar conditions observed in SCplant and SCratoon related to soil water dynamics, sugarcane fields are still susceptible to soil compaction [51,52], mainly in the 10-20 cm layer. The risk of compaction in sugarcane fields is dependent not only on machinery traffic but also on the management system [46].…”

Brazil is the world’s largest sugarcane producer with projections for expanding the current area by 30% in the coming years, mainly in areas previously occupied by pastures. We assess soil water changes induced by land-use change (LUC) for sugarcane expansion in the central-south region of Brazil. For that purpose, soil samples were collected in a typical LUC sequence (native vegetation–pasture–sugarcane) in two contrasting soil textures (i.e., sandy and clayey). Soil hydro-physical properties such as pores size distribution, bulk density, soil water content, water tension, and drainage time at field capacity, plant-available water, and S-index were analyzed. Our data showed that long-term LUC from native vegetation to extensive pasture induced severe degradation in soil physical quality and soil water dynamics. However, conventional tillage used during conversion from pasture to sugarcane did not cause additional degradation on soil structure and soil water dynamics. Over time, sugarcane cultivation slightly impaired soil water and physical conditions, but only in the 10–20 cm layer in both soils. Therefore, we highlight that sustainable management practices to enhance soil physical quality and water dynamics in sugarcane fields are needed to prevent limiting conditions to plant growth and contribute to delivering other ecosystem services.

“…Because of this reduction, they reported higher susceptibility to soil compaction, increasing bulk density, and reducing macroporosity. Cavalcanti et al (2019) show the importance of increasing OM on soil physical properties in a Ultisol grown with sugarcane, which reduces bulk density and minimizes the compaction process. The NB SJ and CH LG had similar behavior, with volume below the critical limit close to DC 90.…”

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.

“…Changes in soil bulk density, water content at the field capacity and soil texture and structure may affected these soil physical functionalities. Furthermore, loss of soil structure and changes in soil texture due to intensive tillage for sugarcane monoculture systems and successive mechanized harvesting with heavy machinery (Silva et al 2018;Cavalcanti et al 2019) during long crop growth cycle seems to have induced consequent changes in pore architecture, soil particle size distribution which caused changes in soil water retention and negatively impacted field capacity.…”

“…It is expected that in the long term, consecutive mechanized harvests and tillage for sugarcane replanting will lead to induce the formation of plough pans, with significant reductions in soil pore spaces and water availability leading to deterioration of soil physical functions for plant growth (Cavalcanti et al 2019(Cavalcanti et al , 2020de Lima et al 2020;Jimenez et al, 2020). Cherubin et al (2016), observed that physical quality of the soil reduced by 90-56% of its full capacity from native vegetation soils to sugarcane as the consecutive monoculture of sugarcane deteriorated the soil physical quality for plant growth.…”

Soil deterioration and yield decline are the main factors affecting the environmental sustainability of long-term irrigated sugarcane monoculture. This research was conducted to detect changes of soil physical, chemical and physicochemical quality parameters associated with intensive irrigated sugarcane monoculture with groundwater for long term. Sugarcane monoculture resulted in a severe impact on some soil physical indicators of soil quality as increased the soil bulk density and reduced soil clay content, decreased soil aggregate stability and the water content at the field capacity causing decreases in soil porosity and decline in soil fertility. Significant impacts on some soil chemical indicators of soil quality were also recorded as reduced soil organic matter content and increased soil pH and EC producing soil salinity. Fields under long-term irrigated sugarcane monoculture had low OM values ranged from 2.09 to 2.61% while areas under crop rotation had the highest OM values ranged from 2.62 to 3.39%. Fields under sugarcane monoculture system had higher pH, EC and SAR values ranged from 7.96 to 8.41, from 2.98 to 4.22 dS m -1 and from 7.75 to 11%, while fields under crop rotation system had the lowest pH, EC and SAR values ranged from 7.64 to 7.92, 1.41 to 2.42 dS m -1 and from 4.51 to 5.86%, respectively. From these results, it could be concluded that long term sugarcane monoculture has significantly deteriorated soil physical and chemical properties indicating the urgent demand for more sustainable management practices to preserve soil quality.
