Resumo: | The northwest area of the State of Parana presents, in most of its extension, loamy to sandy texture soils that, depending on the system of management and tillage of the soil and crops, they can be predisposed to high levels of physical degradation of the soil. With the objective of characterizing the effect of cultivation systems for the cassava crop (Euphorbiaceae) in a Dystrophic Red Latossol (Oxisol), experiments were installed in the experimental area of the Pinduca Ltda Company, Araruna - PR. Three systems of cultivation were adopted: no-tillage of the cassava on the residues of the oats crop following the cultivation of annual crops without disturbing the soil, cultivation areas under minimum tillage with subsoiling, and conventional tillage with moldboard plow and disc harrowing. The physical properties evaluated were the size distribution of the aggregates after dry sieving, the soil resistance to root penetration, the bulk density and the porosity of the soil. The results indicated that the adoption of the different cultivation systems resulted in important alterations in most of the physical properties of the evaluated soil. The mean weight and geometric diameter of the aggregates differed among the systems of cultivation. The no-tillage cultivation system promoted increases in the bulk density of the soil and reduction in the macroporosity in comparison to the plowed systems of soil cultivation. In the absence of disturbing the soil, the soil resistance to penetration was restrictive to the growth of the plants in comparison to the systems of minimum and conventional cultivation of the soil |

O objetivo deste trabalho foi avaliar algumas propriedades físicas de um LATOSSOLO VERMELHO Distrófico, sob três sistemas de preparo do solo, para a implantação da cultura da mandioca (Euphorbiaceae). O experimento foi instalado em área da Fazenda Experimental Pinduca Ltda, Araruna, Estado do Paraná. Os sistemas de preparo adotados foram: plantio direto da mandioca na palhada da cultura da aveia sem revolvimento do solo, plantio em áreas sob preparo mínimo com escarificação e, preparo convencional com aração com arado de aivecas e gradagem. As propriedades físicas do solo avaliadas foram: distribuição dos tamanhos de agregados por peneiramento a seco, resistência do solo à penetração, densidade e porosidade do solo. Os resultados indicaram que os sistemas de preparo considerados levaram a alterações significativas na maioria das propriedades físicas avaliadas. O diâmetro médio ponderado e geométrico dos agregados foi significativamente maior no sistema de plantio direto em relação ao preparo mínimo e o preparo convencional. O plantio direto promoveu aumentos na densidade do solo e redução na macroporosidade em comparação com os outros sistemas de preparo. A resistência do solo à penetração apresentou valores considerados restritivos ao crescimento da cultura da mandioca no tratamento submetido ao sistema de plantio direto, em comparação com os sistemas de preparo mínimo e convencionalUniversidade Estadual de Maringá2008-04-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/227710.4025/actasciagron.v24i0.2277Acta Scientiarum.
