“…The agricultural traffic increased the amount of water stored in the soil, mainly until 10 cm soil depth, which can be attributed to the rearrangement of pores in the soil profile (Moraes et al, 2016a). In the 0-5 cm layer, the water content at field capacity in the plots with one tractor pass increased by 35% -from 0.26 cm 3 cm -3 (without traffic) to 0.35 cm 3 cm -3 , as a function of the increase of soil compaction level, and the consequent reduction of pore size (Moraes et al, 2016a), which favoured improvements in the water retention at more negative potentials (McHugh et al, 2009). This indicates that the traffic favoured increases of plant-available water capacity at 0-10 cm soil depth, mainly after the first pass of the 3.8 Mg tractor, with a tire-ground contact pressure of 120 kPa.…”

“…by which agricultural machines travel in the same places to reduce the level of compaction in cultivated areas (McHugh et al, 2009), which has resulted in increased mean productivity of the areas (Tullberg et al, 2007). The main effects of soil compaction caused by excessive agricultural traffic are the increase of soil bulk density, soil penetration resistance and, consequently, the reduction of total porosity (McPhee et al, 2015), macroporosity (Dal Ferro et al, 2014), soil-water storage (Moraes et al, 2016a) and crop root growth (Bengough, 2012).…”

-The objective of this work was to determine whether compaction by tractor traffic in areas managed under controlled traffic can be limiting to corn crop, under different tillage systems, in a Typic Paleudult of medium texture. Two experiments were carried out, one in the field over two crop seasons and another in a greenhouse. The treatments consisted of minimum tillage with chiselling; no-tillage subjected to one, three, or six passes of a tractor weighing 3.8 Mg; and an area without traffic. Evaluations were performed for soil physicohydraulic parameters (soil bulk density, penetration resistance, and water retention curve), root and shoot growth, and grain yield. The agricultural traffic increased bulk density, soil penetration resistance, and water content at field capacity. The highest values for soil penetration resistance (1,600 kPa) and bulk density (1.67 g cm ) in the trafficked soil were not limiting to corn development and increased grain yield for both crop seasons. Tractor traffic of up to six passes is beneficial to corn cultivation, and it increases water availability and corn grain yield.

“…Porém, o decréscimo na RP foi maior no tratamento livre do tráfego. Estes resultados podem ser explicados em parte pelo sistema de manejo utilizado na área, em que o constante aporte de cobertura vegetal, e a presença de sistema radicular de culturas diferentes (aveia, soja, milho), condicionam a atividade biológica que contribui para a melhoria na estrutura do solo (McHUG et al, 2009). Assim, o tráfego controlado pode contribuir para aprimorar a qualidade do Sistema plantio direto por potencializar os efeitos biológicos na melhoria da estrutura (TULLBERG et al 2007;QINGJIE et al,2009).…”

RESUMO -Organizar o tráfego de máquinas agrícolas que atualmente ocorre de maneira aleatória dentro das áreas comerciais é uma ação com efeito de mitigar os problemas de compactação. Uma vez que o tráfego de máquinas de grande porte sob condições inadequadas de umidade (elevada umidade) do solo, associada com a inadequada rotação de culturas e baixo aporte de massa seca, acaba induzindo a ocorrência da compactação do solo. O controle do tráfego de máquinas agrícolas (tráfego controlado) é uma opção para mitigar as perdas de produtividade das culturas associadas a compactação do solo. Este estudo foi conduzido com o objetivo de avaliar as modificações impostas pelo tráfego controlado de máquinas na resistência do solo a penetração, no desenvolvimento do sistema radicular e na produtividade da soja. O solo do local é classificado como Latossolo Vermelho com textura muito argilosa. Os tratamentos investigados foram: (a) Sem tráfego de máquinas (tratamento de referência) (ST); (b) Tráfego restrito a passagem do conjunto trator-semeadora (TT); e (c) Tráfego máximo acumulando passagens de pulverizador e do conjunto trator-semeadora (TM). O delineamento experimental foi o de blocos inteiramente casualizados, com 3 blocos e 5 repetições. A implantação parcial do sistema de tráfego controlado aumentou a resistência do solo a penetração em locais onde ocorreu o tráfego das máquinas, porém não alcançando valores críticos. O sistema radicular da soja apresentou maior comprimento na camada entre 0,10-0,30 m no tratamento ST, que apresentou produtividade de grãos 7% maior que o tratamento TM, sem apresentar diferença estatística entre eles.Palavras-chave -agricultura de precisão, compactação do solo, penetrometria.Abstract -Controlled traffic farming (CTF) is an efficient tool to mitigate the negative impact of soil compaction in croplands. Since, the traffic of heavy machinery under high soil moisture associate to lack of soil disturbance under no-till, mainly in crop systems with absence of crop rotation result in soil compaction. As alternative to soil management emerge CTF with potential to avoid yield loss by soil compaction and increase machinery efficiency. The objective of this study was to evaluate the changes imposed by CTF in soil penetration resistance and soybean root growth and grain yeld. The soil is classified as an Oxisol and the climate is cfa in Koeppen classification. The treatments investigated were: (a) No traffic, the reference treatment (NT); (b) Planter and tractor traffic (TT) and (c) Maximum Traffic, accumulating sprayer and tractor-planter (MT). The design experimental was a randomized block with 3 blocks and 5 replicates. In this study, a partial CTF was implanted where the traffic caused an increase in soil penetration resistance but the critical values to this parameter was not reached. The ST treatment had a higher soybean root growth in the 0.10 -0.30 m soil layer and a grain yield increase of 7 % in relation to the MT, without stastical difference.

“…Soil compaction is defined as "the process by which the soil grains are rearranged to decrease void space and bring them into closer contact with one another, thereby increasing the bulk density" (Kroulík et al, 2011). Soil compaction leads to negative consequences such as the reduction of soil porosity, decrease of aeration (McHugh et al, 2009), reduction of saturated hydraulic conductivity and an increase in soil resistance to roots exploration (Balbuena et al, 2003;Valdes-Abellan et al, 2015). Some different approaches have been recently proposed in the last year for fast characterisation of soil condition, mainly consisting of sensors mounted on tines or discs allowing on the go data collection (Chukuw & Bowers, 2005;Hemmat et al, 2008;.…”

Soil compaction is a critical issue in agriculture having a significant influence on crop growth. Sugar beet (Beta vulgaris L.) is accounted as a crop susceptible to compaction. Reduction of leaf area, final yield, and root quality parameters are reported in compacted soils. The most obvious visual indicator of topsoil compaction is root depth affected by agricultural tractor and machinery traffic up on the soil. Such indicators are mainly correlated to initial soil condition, tyre features, and number of passages. Monitoring and controlling frequency and position of machine traffic across the field, in such a way that passages are completed on specific, well-defined tracks, can assist with minimization of compaction effects on soil. The objective of the present work was to analyze the subsoil compaction during the growing period of sugar beet with different farming approaches including controlled traffic passages and random traffic. To this end, tests were carried out following each agro technical operation using penetrometer readings in order to monitor the state of cone-index after each step. In addition, at the harvesting time, root quality parameters were analyzed with particular attention to length and regularity of the taproot, total length, circumference, mass, and above-ground biomass. Such parameters were usefully implemented in order to evaluate the effects of controlled traffic passages compared to the random traffic in a cultivation of sugar beet. Results highlight how an increase in crop yield, derived from samples monitored, higher than 10% can be expected with implementation of a careful traffic management.Additional key words: soil; traffic management; compaction; crop parameters.Correspondence should be addressed to Andrea Pezzuolo: andrea.pezzuolo@unipd.itAbbreviations used: CI (cone index); CT (controlled traffic area); CTF (controlled traffic farming); CT0 (soil portion not affect by machines compaction); CT3 (lanes undergoing three machines passes); CT8 (lanes undergoing eight machines passes); RT (random traffic area); WW (work widths).
