Resumo: | This study evaluated alterations in the physical properties water content, soil density and porosity in areas under no tillage and tillage systems in the cultures of soybean and maize in three agricultural years. The experiment was carried out at the Experimental Nucleus of Agricultural Engineering of Unioeste (Cascavel, state of Paraná). Soybean culture occurred in the first two years and in the third year maize, as summer crop, black oats and forage turnip as winter cover crops.. During these three years the study observed reduction of water content and soil density and increase of porosity . The variations as regards the physical properties of the soil showed direct proportional relation between water content and soil density and was in inverse proportion for soil porosity. The soil presented improvements on its physical conditions for the porosity increase and density reduction with the black oats and forage turnip crops and maize. The soybean/maize management in rotation with black oats and forage turnip showed more adequate in the improvement of the physical conditions of the soil as compared with the management systems, since neither of the systems had a major impact in the improvements of the physical properties evaluated throughout this whole period. |

O experimento foi instalado no Núcleo Experimental de Engenharia Agrícola da Unioeste (Cascavel, Estado do Paraná). Nos dois primeiros anos foi implantada a cultura de soja; no terceiro ano, milho, como cultura de verão, e aveia preta e nabo forrageiro, como cobertura de inverno. Durante os três anos, foram observados redução do teor de água e densidade do solo e aumento da porosidade. As variações nas propriedades físicas do solo mostraram relação diretamente proporcional entre teor de água e densidade do solo e inversamente para porosidade. O solo apresentou melhorias nas condições físicas pelo acréscimo de porosidade e redução de densidade com as culturas de aveia preta+nabo forrageiro e milho. O manejo soja/milho em rotação com aveia preta+nabo forrageiro mostrou-se mais adequado na melhoria das condições físicas do solo do que os sistemas de manejo, uma vez que nenhum dos sistemas teve maior destaque na melhoria das propriedades físicas avaliadas em todo o período.Universidade Estadual de Maringá2008-02-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/75510.4025/actasciagron.v29i5.755Acta Scientiarum.
