Resumo: | The objective of this work was to evaluate the soil compaction effect on its physicohydric properties and on chisel energy demand, as well as to quantify the behavior of these properties below the chisel working depth. The experiment was carried out in a sandy loam Alfisol, with the following treatments: no-tillage for 13 years; no-tillage for 13 years and chiseling; no-tillage with additional compaction; and no-tillage with additional compaction and chiseling. Compaction along the chiseling depth was verified through data of traction effort associated to the chisel, obtained with the aid of an octagonal ring linked to a data acquisition module. Soil bulk density, total porosity, macroporosity, microporosity, hydraulic conductivity and soil resistance to mechanical penetration were also determined. Soil compaction increased both soil bulk density and resistance to mechanical penetration, reducing the total porosity and the macroporosity, without causing significant effects in microporosity. The compaction increased chisel energy demand in 21.64%, increasing the mean value of traction effort from 5.33 kN to 6.35 kN. Soil chiseling did not increase soil compaction status below the chisel working depth in the sandy loam Alfisol. |

O trabalho foi conduzido em Argissolo Vermelho-Amarelo de textura francoarenosa, com os seguintes tratamentos: plantio direto por 13 anos; plantio direto por 13 anos em solo escarificado; plantio direto em solo com compactação adicional; e plantio direto em solo com compactação adicional escarificado. A compactação, ao longo da profundidade escarificada, foi verificada por meio dos dados de esforço de tração associados à haste escarificadora, obtidos com auxílio de um anel octogonal ligado a um módulo de aquisição de dados. Foram determinados densidade, porosidade total, macroporosidade, microporosidade, condutividade hidráulica saturada e resistência mecânica do solo à penetração. A compactação elevou a densidade e a resistência mecânica à penetração do solo, reduziu a porosidade total e a macroporosidade, porém sem causar efeitos significativos na microporosidade. A compactação aumentou a demanda energética da haste escarificadora em 21,64%, o que elevou os valores médios de esforço de tração de 5,33 para 6,35 kN. A escarificação não elevou o estado de compactação do solo abaixo da profundidade de trabalho da haste escarificadora, em solo francoarenoso.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPqMentges, Marcelo IvanReichert, José Miguelda Rosa, David PeresVieira, Davi Alexandreda Rosa, Vanderleia TrevisanReinert, Dalvan José2011-01-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7901Pesquisa Agropecuaria Brasileira; v.45, n.3, mar. 2010; 315-321Pesquisa Agropecuária Brasileira; v.45, n.3, mar. 2010; 315-3211678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7901/6021https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/7901/3507info:eu-repo/semantics/openAccess2014-10-17T17:04:49Zoai:ojs.seer.sct.embrapa.br:article/7901Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-17T17:04:49Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
