Resumo: | The objective of this work was to analyze the effect of integrated crop-livestock systems on soil hydraulic properties, and test the potential use of these properties as physical quality indicators of a Cerrado Oxisol. The field study was conducted at Embrapa Cerrados, Planaltina, DF, Brazil, considering soil layers of: 0–5, 10–15, 20–25 and 40–45 cm. Crop-livestock systems caused significant changes in soil bulk density, volumetric soil-water content, soil penetration resistance, total porosity, macroporosity, effective microporosity, unsaturated pores and available water. An increase was observed in both soil resistance and bulk density for all systems in comparison to the cerrado. However, higher soil resistance did not appear as a limiting factor for annual crops growth in a rotation sequence. Total porosity and macroporosity were higher in the cerrado, and in the systems with no-tillage in relation to conventional tillage. Soil penetration resistance, macroporosity, bulk density and available soil-water properties are reliable indicators of the soil physical quality. |

As amostras de solo foram coletadas nas camadas 0–5, 10–15, 20–25 e 40–45 cm. Todos os sistemas de uso e manejo do solo alteraram significativamente a densidade, umidade volumétrica, resistência à penetração, porosidade total, macroporosidade, microporosidade efetiva e água prontamente disponível do solo. Foram observados incrementos na resistência à penetração e na densidade do solo em todos os sistemas em comparação ao cerrado nativo. A compactação resultante do pisoteio animal durante quatro anos da fase pastagem, nos sistemas de integração lavoura-pecuária, não atingiu valores críticos, que pudessem limitar cultivos anuais subseqüentes. A porosidade total e a macroporosidade foram maiores no cerrado e nos sistemas em plantio direto em relação aos em preparo convencional. Os atributos avaliados são indicadores confiáveis da qualidade físico-hídrica do solo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMarchão, Robélio LeandroBalbino, Luiz CarlosSilva, Euzabio Medrado dados Santos Junior, João de Deus Gomesde Sá, Marcos Aurélio CarolinoVilela, LourivalBecquer, Thierry2007-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7641Pesquisa Agropecuaria Brasileira; v.42, n.6, jun. 2007; 873-882Pesquisa Agropecuária Brasileira; v.42, n.6, jun. 2007; 873-8821678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7641/4560info:eu-repo/semantics/openAccess2014-10-10T20:45:50Zoai:ojs.seer.sct.embrapa.br:article/7641Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-10T20:45:50Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
