“…5) may be related to the positive effects of maintaining sugarcane straw on the soil surface. These results are supported by Franco et al (2015), who reported reduction of SOC in deeper layers in these same sugarcane sites. Dalchiavon et al (2013) also verified that maintenance of sugarcane straw on the soil surface increases SOC stocks, decreases bulk density and soil resistance to penetration, and improves sugarcane yield.…”

“…Large root systems promote high C inputs and act on the formation and stabilization of soil structure. Greater C stock within upper soil layers was confirmed by Franco et al (2015), who reported average SOC stock decreases of 6% from 0 to 10 to10 to 20 cm layer and 18% from 0 to 10 to 20 to 30 cm layer in these pasture sites. Roots release a variety of exudates that have a cementing effect on soil particles and they can physically influence microaggregate formation via the compressing action of growing roots and in the entanglement of soil particles to form and stabilize macroaggregates (Tisdall and Oades, 1982;Six et al, 2004;Bronick and Lal, 2005).…”

“…Recently, Franco et al (2015) verified that native vegetation had greater SOC stocks (0-30 cm layer) compared to pasture (average À26%) and sugarcane (average À36%) soils at these same sampling sites. Furthermore, Franco et al (2016) found significantly greater macrofauna diversity in these native vegetation soils than in pasture and sugarcane soils.…”

“…Recent studies have shown that the LUC from pasture to sugarcane depletes soil organic carbon (SOC) stocks Franco et al, 2015) and increases soil susceptibility to compaction due to heavy and intense traffic during mechanical harvest and transport (Braunack and McGarry, 2006;Lozano et al, 2013;Souza et al, 2014). Therefore, soil compaction has been identified as the main concern in modern sugarcane production systems in Brazil (Lozano et al, 2013;Souza et al, 2014) and has been characterized by increases in bulk density, leading to a reduction in macroporosity and water infiltration (Braunack and McGarry, 2006;Castro et al, 2013;Souza et al, 2014).…”

Cherubin, Maurício R.; Franco, André L.C.; Guimarães, Rachel M.L.; Tormena, Cássio A.; Cerri, Carlos E. P.; Karlen, Douglas; and Cerri, Carlos C., "Assessing soil structural quality under Brazilian sugarcane expansion areas using Visual Evaluation of Soil Structure (VESS)" (2017 Increasing global demand for biofuel has accelerated land-use change (LUC) in Brazil, primarily through the planting of sugarcane (Saccharum officinarum) to replace degraded pastures. The intensive mechanization associated with this LUC has increased concerns regarding structural quality of Brazilian tropical soils. Through decades of research focusing on identifying sensitive indicators of soil degradation due to land use and management, the Visual Evaluation of Soil Structure (VESS) method has emerged as a simple, fast, reliable and accurate semi-quantitative approach for assessing soil structure changes. VESS integrates soil properties related to size, strength and porosity of aggregates, and root characteristics into a single score (Sq -structural quality) that ranges from 1 (good structural quality) to 5 (poor structural quality). Although the VESS method was developed for temperate soils, it has been used successfully as an indicator of soil and crop management practice effects on structural quality of tropical and subtropical soils. Our objectives were to evaluate soil structural quality changes associated with a LUC sequence (i.e., native vegetation to pasture to sugarcane) at three sites under Oxisols, Alfisols and Ultisols across centralsouthern Brazil using the VESS; and to correlate VESS scores with quantitative measurements of soil physical properties. Average VESS scores were 2.0, 2.7, and 3.1 for native vegetation, pasture, and sugarcane, respectively. Overall the VESS method was able to detect soil structural quality changes under LUC for sugarcane cultivation, indicating a decrease in soil quality from native vegetation through pasture to sugarcane. The VESS scores were significantly correlated with quantitative soil physical property measurements, suggesting VESS is a reliable indicator of soil structural quality in tropical soils. A VESS score Sq = 3.0 seems to be suitable as a guide for management decisions. We conclude that VESS scores provide an efficient method to identify impacts of sugarcane expansion on soil structural quality, and recommend that VESS assessment be incorporated into monitoring protocols for evaluating not only sugarcane expansion areas, but also overall soil quality/health in Brazil.

“…Após 20 anos de cultivo de cana-de-açúcar foram encontradas perdas de 40 e 35% dos estoques de C e N do solo, resultando em emissão de C em 1,3 Mg ha -1 ano -1 causada pela respiração da MOS (FRANCO et al, 2015). Porém, a substituição da colheita realizada após a queima das folhas pela colheita sem queima favorece o aumento do estoque de C no solo pela redução das emissão de gases do efeito estufa BERNOUX, 2008).…”
