“…Após o tráfego da escavadeira hidráulica adaptada na camada de 0 a 0,10 m, a resistência do solo à penetração apresentou aumento médio de 39%, enquanto após o tráfego do harvester de pneus, o aumento foi de 77% na mesma camada. Essa susceptibilidade na camada de 0 a 0,10 m de profundidade também foi relatada Silva et al (2016). Além disso, estudo de Ampoorter et al (2010) relatam que as alterações físicas do solo tendem a ser mais intensas logo abaixo da linha de tráfego das máquinas.…”

O objetivo foi avaliar a qualidade estrutural do solo após corte florestal com harvester de pneus e escavadeira hidráulica adaptada em LATOSSOLO VERMELHO distrófico típico. O experimento foi delineado de forma inteiramente casualizada com instalação de quatro unidades amostrais com três pontos de repetição. Além disso, foram coletadas amostras de solo na trilha de tráfego dos rodados da máquina nas camadas de 0 a 0,10; 0,11 a 0,20; 0,21 a 0,30; e 0,31 a 0,40 m de profundidade para determinação dos parâmetros de densidade e porosidade total e, também, foi mensurada a resistência do solo à penetração na trilha dos rodados e entre rodados. Dessa forma, foi possível determinar que a densidade e a porosidade total média antes do tráfego das máquinas foram de 1,10 g cm-3 e 53,85%, respectivamente, ocorrendo efeitos significativos nessas variáveis após o tráfego do harvester de pneus em todas as camadas avaliadas. Quanto a resistência do solo à penetração, verificou-se que houve aumento significativo na trilha dos rodados do harvester, tanto de pneus como de escavadeira, contudo, havendo incremento de cerca de 77% na camada de 0,10 m após tráfego do harvester de pneus.

“…According to Severiano et al (2010), the adoption of preventive measures to avoid additional soil compaction by mechanical sugarcane harvesting is recommended, including the control of pressure level per axle of the machine (Bennett et al, 2015), as well as, control of the inflating pressure of tires and increasing the number of axles of trailers, reducing thus the load applied on soil by the machine. Traffic over crop residues has also been suggested as a preven- tive measure, in addition to monitoring soil moisture to perform agricultural driving at moisture contents below the limit (Silva et al, 2016). These preventive traffic control measures (Sousa et al, 2017) may be a promising alternative to avoid the spread of soil compaction throughout the entire sugarcane cultivation area.…”

Mechanical sugarcane harvesting increases soil compaction due to the intense traffic of agricultural machinery, reducing longevity of sugarcane crops. In order to mitigate the harmful effects caused by agricultural traffic on the soil structure in sugarcane fields, this study evaluated impacts of mechanical sugarcane harvesting on traffic lane under two soil tillage systems based on load bearing capacity models. The experiment was carried out in the region of Piracicaba, state of São Paulo, Brazil, on a Rhodic Nitisol, under conventional tillage (CT) and deep strip-tillage (DST). For CT soil tillage was applied to the entire area with a heavy disk harrow, at operating depths from 0.20 to 0.30 m followed by a leveling harrow at a depth of 0.15 m. For DST, soil tillage was performed in part of the area at a depth of 0.80 m, forming strip beds for sugarcane planting, while the traffic lanes were not disturbed. Undisturbed soil samples from traffic lanes were used in the uniaxial compression test to quantify preconsolidation pressure and to model the soil load bearing capacity. The surface layer (0.00-0.10 m) was most susceptible to compaction, regardless of the tillage system (CT or DST) used. In the DST, the traffic lane maintained the previous soil stress history and presented higher load bearing capacity (LBC) than the traffic lane in the CT. As in CT the soil was tilled, the stress history was discontinued. This larger LBC in DTS minimized the impacts of the sugarcane harvest. Under CT, additional soil compaction due to mechanical sugarcane harvesting in the traffic lane was observed after the second sugarcane harvest. There was a reduction in load bearing capacity from 165 kPa to 68 kPa under CT and from 230 kPa to 108 kPa under DST, from the first to the second harvest at surface layer. Water content at mechanical harvesting was the most relevant factor to maximize impacts on the soil structure in traffic lanes, for both tillage systems.

“…The precompression stress (σp) is derived from the compression curve, which is a plot of the changes in soil bulk density or void ratio against the logarithm of the applied pressure to the soil. The application of pressure lower than the σp to the soil causes an elastic (recoverable) deformation, but when the pressure applied to the soil is higher than the σp, irrecoverable plastic deformation of the soil structure occurs (SILVA et al, 2016). Consequently, σp has been used by several authors as an indicator of sustainability of soil structure under varying load-bearing conditions (GONTIJO et al, 2011).…”

The intensive agricultural machinery traffic to which soils under coffee crops are exposed may cause significant changes in soil structure. The goals of this study were to: a) characterize the spatial variability of precompression stress (σp) and volumetric water content (θ) of a Red-Yellow Latosol (Oxisol) and determine their spatially dependent structures using ordinary kriging semivariograms; b) using this date to construct a load-bearing capacity (LBC) map for the site, identifying the depth with higher ; and c) use the map as a decision support tool regarding agricultural machinery logistic management in coffee plantations. The research was conducted on an experimental farm of the Agricultural Research Company of Minas Gerais (Epamig), Patrocinio, MG, on a clayey Oxisol. Samples were collected from 2.0 × 1.5 m sampling pits at intersections of a rectangular 40 × 150 m grid, totaling 28 sampling points. The soil samples were collected with metal rings (0.0254 m in height and 0.0630 m in diameter) using an Uhland sampler. Sampling at each pit was at 3 layers: 0.00–0.03 m, 0.10–0.13 m, and 0.25–0.28 m, and seven samples arranged in a matrix form were collected at each layer, totaling 588 samples. The σp and θ showed a spatially dependent structure. The depth of 0.00–0.03 m showed higher LBC, indicating that this depth was more compacted compared to other depths. Based on the σp maps, the tractor and the combine should not traffic into the areas at water content of 0.45 m3 m-3, because the soil has a LBC of 200 kPa. If this condition is not respected, additional compaction will occur. Tractor traffic is permissible when the water content reaches values less than 0.36 m3 m-3, whereas for combine traffic, the water content values must be less than 0.30 m3 m-3.
