Least Limiting Water Range and Load Bearing Capacity of Soil under Types of Tractor-Trailers for Mechanical Harvesting of Green Sugarcane

Abstract: The expansion of the sugarcane industry in Brazil has intensified the mechanization of agriculture and caused effects on the soil physical quality. the purpose of this study was to evaluate the limiting water range and soil bearing capacity of a Latossolo vermelho distroférrico típico (Rhodic Hapludox) under the influence of different tractor-trailers used in mechanical sugarcane harvesting. the experiment was arranged in a randomized block design with five replications. The treatments consisted of green sugar… Show more

“…After reaching equilibrium at each potential, the samples were weighed. The RP was determined by means of an electronic penetrograph with a constant penetration velocity of 0.01 m min -1 , base diameter of 4 mm and semi-angle of 30° (Pereira et al, 2015). After determination of PR, the samples were taken to greenhouse for drying and then the soil bulk density (sD) was obtained by the relation between the dry soil mass at 110 ºC for 24 h and the volumetric ring volume at which the soil was collected (Arcoverde et al, 2019).…”

“…For the determination of the LLWR, followed the procedures described by Pereira et al (2015), considering the upper limit to be the lowest value among the water content retained in the soil at a matric potential of -0.01 MPa (Reichardt, 1988), corresponding to field capacity (SWF C ) or the value at which the air-filled porosity (SWF C ) was 10% (Grable & Siemer, 1968). In turn which, the lower limit was considered to be the greatest value among the retained water contents at a matric potential of -1.5 MPa (Savage et al, 1996) in relation to the permanent wilting point (SW PWP ), and the soil moisture content at root penetration (SW PR ) reaches 2.0 MPa (Taylor et al, 1966;Pereira et al, 2015) and 4.0 MPa for sugarcane (Oliveira Filho et al, 2016).…”

“…Soil compression curves have also been used to identify structural changes in the soil caused by compaction. Modeling evaluates load-bearing capacity (LBC), which indicates the maximum pressure that the soil can bear under different moisture levels without increasing compaction (Pereira et al, 2015).…”

“…In Brazil, soil compression curves have been widely used to evaluate soil response in reference to different soil properties and management practices, such as tillage systems (Silva et al, 2002a,b;Veiga et al, 2007), grazed pasture and eucalyptus forest (Suzuki et al, 2015), orange orchard (Fidalski et al, 2015), Oxisols with different textures (Severiano et al, 2011), sugar cane crop (Pacheco and Cantalice, 2011;Pereira et al, 2015), pastures (Pires et al, 2012), coffee crop (Araujo-Junior et al, 2011;Pais et al, 2013), and agroforestry systems (Watanabe et al, 2016). Other studies have focused on investigating the methods applied in determination of σ p and pedotransfer functions (Dias Junior and Pierce, 1996;Imhoff et al, 2004;Cavalieri et al, 2008;Suzuki et al, 2008;Severiano et al, 2011;Silva and Lima, 2016).…”
