“…In each plot one trench was opened perpendicular to the plant rows and between two plant rows to collect 18 monoliths (width 0.25, height 0.10, length 0.10 m), according to Vasconcelos et al (2003) and Otto et al (2009Otto et al ( , 2011. The monoliths were collected with a stainless steel box, with openings in the top and bottom, which was driven into the soil in the trench wall at the same points and layers used for soil sampling.…”

“…The root images were scanned in an optical scanner (resolution 400 dpi) to analyze root diameter, density, surface area and volume using software SAFIRA®. The roots were dried in a forcedair oven at 65 °C to constant weight, to determine dry matter (Otto et al, 2009(Otto et al, , 2011.…”

“…Soil compaction also affects the soil structure, changing the aggregate stability and modifying the particle arrangement (Tullberg et al, 2007;Roque et al, 2010;Vezzani & Mielniczuk, 2011). These changes create a less favorable environment for the development of the cane root system (Alvarez et al, 2000;Otto et al, 2009Otto et al, , 2011, reducing the productivity (Paulino et al, 2004;Braunack & McGarry, 2006). Agricultural managers are concerned about the restrictions in the soil for root development in sugarcane fields, for hampering the commercial production (Smith et al, 2005).…”

SUMMARYThe cultivation of sugarcane with intensive use of machinery, especially for harvest, induces soil compaction, affecting the crop development. The control of agricultural traffic is an alternative of management in the sector, with a view to preserve the soil physical quality, resulting in increased sugarcane root growth, productivity and technological quality. The objective of this study was to evaluate the physical quality of an Oxisol with and without control traffic and the resulting effects on sugarcane root development, productivity and technological quality. The following managements were tested: no traffic control (NTC), traffic control consisting of an adjustment of the track width of the tractor and sugarcane trailer (TC1) and traffic control consisting of an adjustment of the track width of the tractor and trailer and use of an autopilot (TC2). Soil samples were collected (layers 0. 00-0.10; 0.10-0.20 and 0.20-0.30 m) in the plant rows, inter-row center and seedbed region, 0.30 m away from the plant row. The productivity was measured with a specific weighing scale. The technological variables of sugarcane were measured in each plot. Soil cores were collected to analyze the root system. In TC2, the soil bulk density and compaction degree were lowest and total porosity and macroporosity highest in the plant row. Soil penetration resistance in the plant row, was less than 2 MPa in TC1 and TC2. Soil aggregation and total organic carbon did not differ between the management systems. The root surface and volume were increased in TC1 and TC2, with higher productivity and sugar yield than under NTC. The sugarcane variables did not differ between the managements. O cultivo do canavial com uso intenso de máquinas, principalmente na colheita, resulta na compactação do solo, o que influencia no desenvolvimento da cultura. O manejo com controle de tráfego agrícola representa uma alternativa ao setor, podendo preservar a qualidade física do solo, resultando em maior crescimento radicular, produtividade e qualidade da cana. Objetivou-se com este trabalho avaliar a qualidade física de um Latossolo Vermelho com e sem controle de tráfego agrícola e seu efeito no desenvolvimento radicular, na produtividade e na qualidade tecnológica da cana-de-açúcar. Os manejos avaliados foram: testemunha sem controle de tráfego (NTC), controle de tráfego com ajuste da bitola do trator e do transbordo de cana colhida (TC1) e controle de tráfego com ajuste da bitola e uso de piloto automático (TC2). Amostras de solo foram coletadas nas camadas 0,00-0,10; 0,10-0,20; e 0,20-0,30 m nas linhas de plantio e do rodado (entrelinha) e na região do canteiro, distante 0,30 m da linha de plantio. A produtividade foi medida com balança específica para transbordo. As variáveis tecnológicas da cana foram medidas em cada parcela. Os monólitos de solo foram coletados para análise do sistema radicular. O TC2 apresentou menor densidade e grau de compactação e maior porosidade total e macroporosidade na linha de plantio. A resistência do solo à pe...

“…Besides these factors, the determination of SPR values depends on soil bulk density (Db) (OTTO et al, 2011), water content in the soil (ASSIS et al, 2009;FIGUEIREDO et al, 2011;MORAES et al, 2012), soil pore-water pressure (FREUDLUND et al, 1978;KIM et al, 2008), particle size distribution (VAZ et al, 2011), clay content (MOLIN et al, 2006, soil type (SILVA et al, 2004), soil compressibility , and soil-metal friction (DEXTER et al, 2007).…”

“…This effect is directly associated with the reduction in the availability of water in the soil, soil aeration, and nutrients to plants, along with the increase of soil resistance to root growth (LETEY, 1985;MEDEIROS et al, 2010). Among various methods to determine the state of soil compaction and physical quality, the evaluation of soil penetration resistance (SPR) has been commonly used in experimental studies, not only related to precision agriculture (SILVA et al, 2004;BOTTEGA et al, 2011;CHERUBIN et al, 2011;DALCHIAVON et al, 2011;GIRARDELLO et al, 2011) but also to assessments of management conditions of agricultural areas (GOEDERT et al, 2002;NEIRO et al, 2003;FREDDI et al, 2007;SILVA et al, 2009;CALONEGO & ROSOLEM, 2011;OTTO et al, 2011) and forests (SEIXAS & SOUZA, 2007;SINNETT et al, 2008).…”

Soil physical quality can be easily and quickly evaluated by using simple equipment to identify levels of soil compaction. Hence, it is necessary to know the variables responsible for changes in the soil penetration resistance (SPR). The aim of this review is to identify the main factors related to the various equipment used for assessing SPR as a soil physical quality indicator in agriculture. This literature review describes the different types of equipment used and its relationship with SPR. A wide range of procedures, devices, and equipments are available. Much of variability in SPR results is related to the equipment model, cone angle and diameter, and penetration rate. Usually, restrictions to root growth are correlated with SPR values above 2-3 MPa. However, comparisons of SPR values obtained under different soil moisture regimes in the same soil type have provided conflicting results of difficult interpretation. In order to minimize these problems, there is a need for standardization of measurement procedures and interpretation, and/or correction of SPR values according to a soil water content of reference.
