“…Seraut (1990) studied different types of tires with a pressure of 0.08 to 0.16 MPa, and found that the pressure at the soil surface was similar to the tire inflation pressure and the pressure in the soil, at a depth of 0.30 m, was directly related to that of the tire. Porterfield and Carpenter (1986), based on the mean contact pressure of a tire on a rigid surface, found that the surface compaction level depends on the contact pressure, whereas deep compaction depends on the contact area, width of the tire and the load it bears.…”

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 sugarcane harvesting with: harvester without trailer (t1); harvester with two trailers with a capacity of 10 mg each (t2); harvester with trailer with a capacity of 20 mg (t3) and harvester and truck with trailer with a capacity of 20 mg (10 mg per compartment) (t4). the least limiting water range and soil bearing capacity were evaluated. the transport equipment to remove the harvested sugarcane from the field (trailer) at harvest decreased the least limiting water range, reducing the structural soil quality. the truck trailer caused the greatest impact on the soil physical properties studied. the soil load bearing capacity was unaffected by the treatments, since the pressure of the harvester (t1) exceeded the pre-consolidation pressure of the soil.

“…Because this study characterized responses to a wide range of skidder traffic intensities of one skidder (i.e., a Timberjack 450C grapple skidder) at a single site with a particular set of soil characteristics, the intensity of the responses should not be extrapolated to sites of differing conditions. For example, the exact magnitude of soil compaction caused by skidder traffic is dependent on a number of soil characteristics such as soil type, soil depth, soil texture, soil moisture content, surface organic layer thickness, and coarse rock content (e.g., Mace, 1971;Greacen and Sands, 1980;Corns, 1988;Williamson and Neilsen, 2000) and characteristics of the skidder such as tire width, tire pressure and wear (e.g., Porterfield and Carpenter, 1986). However, because the nature of the responses is consistent with findings from related studies, a pattern is beginning to emerge with respect to the sensitivity of the ground flora to skidder traffic and the potential advantages of restricting traffic to a designated trail system.…”

“…Porterfield and Carpenter (1986) indicate that the shallow compression level depends mainly on the contact pressure and deep compression depends on the area and contact pressure applied to the soil and width of the tire.…”

Contact pressures and the impact of farm equipment on Latosol with the presence and absence of sugarcane straw

High contact pressures applied to soil result in a greater degree of compaction, in addition to promoting other negative effects. The objective of this study was to quantify contact areas by using different methodologies, and pressures of farm equipment employed in production activity and evaluate structural changes caused in a Red Latosol with the presence and absence of straw cover. The design was completely randomized in a factorial scheme of type 4 (tire on front axle, tire on rear axle, tire on a sugarcane wagon and metallic track of sugar cane Harvester) x 2 (presence and absence of straw). The contact area (CA) of the run was obtained by three procedures: analytical measure of the area of an ellipse (CA1); digital measurement of area of an ellipse (CA2); and measurement of real contact area (RCA), with digital resources. The contact pressure was calculated from the ratio of mass of each machine's axle and the contact area of the run. The contact area obtained according to the procedure of the ellipse (CA1 and CA2) is overrated when compared to actual area obtained digitally (RCA). The straw reduces the contact pressure in the soil, due to the deep tire treads and consequently, increased contact area. Areas where the traffic of the machines occurred with soil covered with the presence of straw showed reduced soil resistance to penetration, cone index and pre-consolidation pressure, confirming that the increased contact area produced by straw reduced the pressure applied and the compression power dissipated in the soil.

RESUMOAltas pressões de contato aplicadas ao solo resultam em um maior grau de compactação deste, além de promover outros efeitos maléficos. O objetivo deste estudo foi quantificar as áreas e pressões de contato de conjuntos motomecanizados empregados na atividade sucroalcooleira e avaliar as alterações estruturais proporcionadas em um Latossolo Vermelho com e sem cobertura de resíduos vegetais (palha). O delineamento empregado foi o inteiramente casualizado em esquema fatorial do tipo 4 (pneu acoplado no eixo dianteiro, pneu acoplado no eixo traseiro, pneu acoplado a um transbordo agrícola canavieiro e esteira metálica de colhedora de cana de açúcar) x 2 (com e sem palha na superfície). A área de contato (CA) dos rodados foi obtida por três procedimentos: medida analítica da área de uma elipse (CA1); medida digital da área de uma elipse (CA2); e medida da área de contato real (RCA), com recursos digitais. A pressão de contato foi calculada a partir da relação da massa dos eixos de cada conjunto motomecanizado e a respectiva área de contato do rodado. A área de contato obtida de acordo com o procedimento da elipse (CA1 e CA2) é superestimada quando comparada área real, obtida digitalmente (RCA). Os resíduos vegetais diminuem a pressão de contato na interface rodado-solo, devido ao maior aprofundamento das garras do rodado e por consequência, aumento da área de contato.
