“…Although a higher bulk density in PA in comparison to NV was observed, this increase did not reflect in alterations in h FC and t FC in the Clayey soil. However, the lower stocking rate during grazing in the Clayey soil when compared to the Sandy soil (Table 2) can be an important aspect [36] that attenuated water dynamic changes in this soil. In addition, it should be noted that excessive soil water retention at higher h in PA can impair grass growth, due to a limited supply of oxygen to plants, since macropores were <0.10 m 3 m −3 , which is considered critical for air fluxes in the soil [37].…”

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.

“…Indeed, increased soil density and reduced total porosity were observed as a result of grazing one year after the first experiment was established [60] and confirmed seven years later [61] , but these changes were reversed with each soybean cycle. Generally, grazing intensity did not affect these soil attributes, except for one study [67] . In this study, increased soil bulk density and decreased macro porosity and total porosity were detected in the top 5 cm of soil under intense and moderate grazing intensities (10 and 20 cm sward height, respectively) compared to lighter grazing intensities (30 and 40 cm sward height) and the ungrazed treatment.…”

“…The development of conservationist systems such as the CLI system increases the soil-water infiltration rates (Bell et al, 2011;Bono et al, 2012;Bonetti, Anghinoni, Gubiani, Cecagno, & Moraes, 2019), verified by the increase in grazing time with the supply and maintenance of crop residues on the soil surface, both for annual crops and pastures (Lanzanova et al, 2007). However, soil water infiltration can decrease depending on the intensity of cattle trampling and grazing management (Tuffour, Bonsu, & Khalid, 2014).…”

“…Alternatively, BIR values obtained from water infiltration rate curves in CLI systems have been used to compare other land-use systems (Bono et al, 2012;Sone et al, 2019;Andrade, Ferreira, Ponciano, & Ponciano, 2020). In this context, grazing height is one of the variables experimentally used in CLI systems (Barbosa et al, 2013;Fidalski & Alves, 2015b;Bonetti et al, 2019), which could be used to estimate other variables.…”

Grazing intensity on palisade grass as a function of grazing height in a crop-livestock integration (CLI) system alters the structural soil quality and water infiltration. This study aimed to verify the magnitude of the stocking rate and shoot and root dry matter of palisade grass at the end of the fifth cattle grazing period of an experiment in the CLI system on the visual evaluation of soil structure (VESS), soil-water infiltration rate, and basic infiltration rate (BIR) as a function of grazing heights on Urochloa brizantha cv. MG 5 Vitória in the northwestern Paraná State, Brazil. The experimental design consisted of randomized blocks with three replications and 1-ha experimental plots on an Oxisol. Four treatments with grazing heights of 10, 20, 30, and 40 cm were used in the CLI system, controlled with variable stocking rates of Purunã cattle in the autumn/winter season on Urochloa brizantha cv. MG 5 Vitória in succession to soybean in the summer. The maximum soil water infiltration was stabilized at 30 cm of grazing height of the palisade grass under continuous grazing in the CLI system. The increase in the stocking rate decreased the shoot dry matter of palisade grass, soil water infiltration, and structural soil quality.
