Resumo: | The objective of this study was to evaluate the chiseling effect duration in an Oxisol, based on the study of soil and planter shank relation. The treatments were: no-till for 13 years; four years since chiseling (2001); two years since chiseling (2002); and six months since chiseling (2005), where all treatments were submitted or not to traffic with agricultural machinery. Data about vertical force and moment associated to: shank, soil mobilized area, specific operational resistance, macroporosity, microporosity, total porosity and soil density, were collected, and draught on shank was calculated. Increasing of time since chiseling required increasing of the forces, and six months since chiseling showed the smallest demand. Four years since chiseling had similar behavior to the no-till treatment, resulting in the smallest soil mobilized area and the greatest operational resistance. Physical property differences occurred only in layer 0–0.10 m, and recent chiseling showed the greatest soil macroporosity, and the smallest soil microporosity and bulk density. After four years, chiseling effect was not found on soil-planter shank relations. |

Os tratamentos foram: solo sob semeadura direta há 13 anos; solo escarificado há quatro anos (2001); solo escarificado há dois anos (2003); e solo escarificado há seis meses (2005), todos com ou sem tráfego de máquinas agrícolas. Dados de esforço vertical, momento associado à haste sulcadora, área de solo efetivamente mobilizada, resistência específica operacional, macroporosidade, microporosidade, porosidade total e densidade do solo foram coletados, e o esforço de tração na haste sulcadora foi calculado. A demanda de esforços aumentou com o incremento no decurso do tempo de execução da escarificação, e o solo escarificado há seis meses apresentou a menor demanda. O solo escarificado há quatro anos apresentou comportamento similar ao solo sob semeadura direta, e ofereceu a menor área mobilizada e a maior resistência operacional. Nos parâmetros físicos, diferenças foram observadas apenas na camada 0–0,10 m, onde o solo recém escarificado apresentou a maior macroporosidade, e menor microporosidade e densidade do solo. Após quatro anos, não se evidenciou mais o efeito da escarificação na relação entre solo e haste sulcadora.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraEmbrapa TrigoRosa, David Peres daReichert, José MiguelSattler, ArcenioReinert, Dalvan JoséMentges, Marcelo IvanVieira, Davi Alexandre2008-10-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/28Pesquisa Agropecuaria Brasileira; v.43, n.3, mar. 2008; 395-400Pesquisa Agropecuária Brasileira; v.43, n.3, mar. 2008; 395-4001678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/28/213https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/28/36https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/28/37https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/28/38info:eu-repo/semantics/openAccess2014-04-30T18:21:02Zoai:ojs.seer.sct.embrapa.br:article/28Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-30T18:21:02Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
