Resumo: The study aimed at assessing the degree of modification of certain physical properties and of the colour of the superficial soil layer of a Dark-Red Latosol of medium texture, subjected to the continuous cultivation of sugar cane during 25 years in Jaboticabal, SP, Brazil. The treatments consisted of two types of soil use, i.e. absence of cultivation (native vegetation) and intense cultivation with sugar cane, at three depth levels of 0-10, 10-20 and 20-30 cm. The continuous cultivation altered the colour of the level 0-10 cm from 2.5YR2.5/4 (absence of cultivation) to 2.5YR3/4, and impaired the macro structure and lessened the degree of flocculation of the soil's clay.

Os tratamentos foram constituídos por dois tipos de uso do solo, ou seja, ausência de cultivo (vegetação nativa) e cultivo intenso com cana-de-açúcar e por três profundidades no perfil, 0-10, 10-20 e 20-30 cm. O cultivo intenso e contínuo alterou a cor do solo na camada de 0-10 cm de 2,5YR 2,5/4 na ausência de cultivo para 2,5YR3/4 e degradou a macroestrutura, reduzindo o grau de floculação da argila do solo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPrado, Renato de MelloCenturion, José Frederico2001-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6113Pesquisa Agropecuaria Brasileira; v.36, n.1, jan. 2001; 197-203Pesquisa Agropecuária Brasileira; v.36, n.1, jan. 2001; 197-2031678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6113/3180info:eu-repo/semantics/openAccess2014-09-16T18:16:23Zoai:ojs.seer.sct.embrapa.br:article/6113Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-16T18:16:23Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
