Resumo: The study was carried in 2002, in Rolandia, north of Paraná State, and had as objective to asses the chemistry modifications on a clayey Oxisol, comparing the conventional management system of sugar cane used by growers of Rolandia Cooperative Agriculture, and the systems of no tillage with wheat crop in rotation with others crops, both with eight years of succession, using as reference a native vegetation area localized beside the evaluated systems. Six trenches were digged in each system, for carrying about morphological study by the method of Crop Profile. Based on the identification of the homogeneous morphological units found in the description of the soil profile, samples were taken for chemistry analysis. No tillage system improved the main chemistry and morphological soil characteristics in the 0-0.40 m layer. Sugar cane conventional system exhausts the soil in some profile structures. The Crop Profile Method helped to have an appropriate notion about the main changes found in the studied treatments.

Foram abertas seis trincheiras em cada sistema avaliado, para realização do estudo morfológico pelo método do perfil de manejo utilizado na identificação das unidades morfologicamente homogêneas que serviram para nortear a retirada de amostras para as análises químicas. O Sistema plantio direto melhorou as condições químicas do solo nos primeiro 40 cm de profundidade. O sistema convencional com cultivo de cana-de-açúcar esgota o solo em determinadas regiões em relação a outras. O método do perfil de manejo permitiu uma adequada percepção das principais alterações encontradas nos tratamentos estudados e se mostrou muito útil na delimitação de regiões distintas, facilitando a amostragem.UEL2008-09-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/276010.5433/1679-0359.2008v29n3p485Semina: Ciências Agrárias; Vol. 29 No. 3 (2008); 485-498Semina: Ciências Agrárias; v. 29 n. 3 (2008); 485-4981679-03591676-546Xreponame:Semina.
