“…Resistance to penetration is a soil quality indicative that may indicate the effects of sugarcane cultivation. Some growing areas may have compaction levels above the critical value in more than half of the sites evaluated (Oliveira Filho et al, 2015), thus showing the impact of sugarcane on the physical properties of the soil.…”

ABSTRACT:The objective of this study was to evaluate from physical and mechanical parameters the evolution of the compaction of an Oxisol in areas with different sugarcane cultivation times in the city of Salto do Jacuí, RS. The evaluations were conducted in areas with two, four e six years of cultivation and an area of native forest. Soil samples with preserved structure were collected in soil layers from 0.00 to 0.05 m; 0.05 to 0.10 m; and 0.10 to 0.20 m, as to determine soil physical and mechanical attributes. The results have shown that over time conventional sugarcane cultivation provides an increase in soil bulk density and soil penetration resistance values and a decrease in soil porosity, mainly due to the reduce in soil macroporosity. These changes are of such magnitude that they can be considered restrictive to root development. In six years of cultivation, the bulk density was closer to the preconsolidation pressure density value, indicating higher soil degradation.Key words: bulk density; penetration resistance; soil compaction; soil porosity Atributos físico-mecânicos de um Latossolo Vermelho em áreas com diferentes tempos de cultivo de cana-de-açúcar RESUMO: O objetivo deste trabalho foi avaliar, a partir de parâmetros físicos e mecânicos, a evolução da compactação de um Latossolo Vermelho em áreas com diferentes tempos de cultivo de cana-de-açúcar no município de Salto do Jacuí, RS. As avaliações foram realizadas em áreas com dois, quatro e seis anos de cultivo e em uma área de mata nativa. Amostras de solo com estrutura preservada foram coletadas nas camadas de 0,00 a 0,05 m; 0,05 a 0,10 m e 0,10 a 0,20 m para determinação dos atributos físicos e mecânicos do solo. Os resultados mostraram que, ao longo do tempo o cultivo convencional da cana-deaçúcar proporciona um aumento na densidade e nos valores de resistência à penetração do solo e diminuição da porosidade do solo, principalmente pela diminuição da macroporosidade. Essas alterações são de tal magnitude, que podem ser consideradas restritivas ao desenvolvimento radicular. Em áreas com seis anos de cultivo, a densidade esteve mais próxima do valor de densidade na pressão de preconsolidação, indicando uma maior degradação do solo. Palavras

“…Soil compaction influences all stages of crop development. Nevertheless, in many areas with low sugarcane yields, the critical values and effects of soil compaction are ignored, while the producers claim not to know the location and intensity of soil compaction (Oliveira Filho et al, 2015).…”

Soil tillage that maintains the productivity of sugarcane plantations, providing an area for the root development and without traffic on crop rows, has given rise to new technologies in rural areas. the purpose of this study was to evaluate the soil physical properties in two sugarcane plantations, one of which was prepared with deep tilling and the other with conventional tillage. the experiment was conducted in lençóis paulista, São paulo State. Soil penetration resistance and relative density were analyzed. the cone index was lower in deep-tilled soil without traffic in all layers, than in deep-tilled soil with traffic and in conventional tillage. In both tillage treatments, the relative density values were acceptable in the 0.00-0.15 m soil layer, but considered detrimental for sugarcane development in the 0.15-0.30 and 0.30-0.45 m layers.

“…Sugarcane cultivation systems involve a large number of operations with heavy farm machinery as tilling, mechanized harvesting and in-field transport, which raise the possibility of compaction and increased soil density (Cavalieri et al, 2011). Repetitive in-field traffic during the crop cycle, which occurs under different soil moisture conditions (Oliveira Filho et al, 2015), hampers normal root development and crop productivity. This set of tilling operations reduces soil macroporosity, aggregate size, water infiltration, and increases soil density and resistance to root penetration (Vasconcelos et al, 2010), thus reducing the performance of the crop.…”

The cultivation systems of sugarcane can cause changes to the soil's physical properties and root development, which in turn, can affect the productivity of the crop. The main objective of this study was to evaluate different soil management systems and their influence on the physical attributes of soil, plant root system development and the productivity of plant cane in re-established area. The experimental design was randomized blocks in 6 x 3 factorial scheme with 4 repetitions. The soil treatments were: T 1 = Desiccation + moldboard plowing + light harrow (DPH); T 2 = Subsoiler + light harrow (SH); T 3 = Desiccation + no-tillage (DNT); T 4 = Desiccation + subsoiler (DS); T 5 = stubble thrasher + subsoiler (StS) and T 6 = stubble thrasher + mid harrow + moldboard plow + light harrow (StHPH), each evaluated at three depths (0.0-0.20; 0.20-0.40 and 0.40-0.60 m). The effects of these treatments were evaluated by analyzing physical properties of soil, root development of the plants and productivity of the crop. All evaluated tillage systems improved penetration resistance, but only to the depth of 0.20 m. The best rates of root development occurred with the T1 treatment. Root development was significantly lower with higher penetration resistance values in all evaluated systems. Sugarcane productivity was significantly higher in systems with greater soil disturbance.
