Resumo: | The objectives of this work were: a) to develop bearing capacity models for a Yellow Red Latossol cultivated with coffee, in function of the associated methods of weed control, pre-consolidation pressure and moisture; b) to identify, through these models, the weed control method most resistant and most susceptible to soil compaction between the rows and in the traffic lines. The experiment was set up at the EPAMIG Experimental Farm in Patrocínio, Minas Gerais state, in a coffee field (Coffea arabica L.). The methods of weed control were: between the rows: rotary tiller, disk harrow, were mower and no weeding (control). In each management system, 15 samples were collected at 0-3, 10-13 and 25-28 cm depths (totalizing 315 samples) to generate the bearing capacity model both between the lines and in the traffic lines, except for the control treatment, where sampling was done only between the lines. To obtain the bearing capacity models, the undisturbed soil samples with different moisture contents were subjected to uni-axial compaction. Between the rows, the rotary tiller and were mowers, at 0-3, 10-13 and 25-28 cm, promoted soil compaction, while the grade harrow promoted a relief of the soil’s mechanical resistance at the same depths. In the traffic line, the rotary tiller, at 0-3 cm, was the method of weed control most susceptible to compaction; at 10-13 cm the rotary tiller, disk harrow and were mower promoted soil compaction; at 25-28 cm a higher susceptibility was observed with the were mower. |

Objetivou-se, neste estudo: a) desenvolver modelos de capacidade de suporte de carga (CSC), para um LVA cultivado com cafeeiro, em função dos métodos associados de controle de plantas invasoras, pressão de preconsolidação e umidade b) identificar, através do uso desses modelos, o método de controle mais resistente e mais suscetível à compactação, nas entrelinhas (EL) e linhas de tráfego (LT). O estudo foi conduzido na Fazenda Experimental da EPAMIG de Patrocínio MG, em uma lavoura cafeeira (Coffea arabica L.). Os métodos de controle utilizados foram: nas entrelinhas - enxada rotativa, grade de disco, roçadora e sem capina (testemunha). Para cada condição de manejo, coletou-se nas profundidades 0-3, 10-13 e 25-28 cm, 15 amostras para gerar o modelo de CSC, tanto nas EL como nas LT, totalizando 315 amostras, com exceção do método sem capina, em que foi realizado apenas nas entrelinhas. Para a obtenção dos modelos, as amostras com diferentes umidades foram submetidas ao ensaio de compressão. Nas EL, a enxada rotativa, roçadora e grade de discos nas profundidades 0-3, 10-13 e 25-28 cm promoveram compactação do solo, enquanto que a grade de discos, nas mesmas profundidades, proporcionou um alívio da resistência mecânica do solo. Na LT, como método de controle a enxada rotativa, na profundidade de 0-3 cm foi o método de controle mais susceptível à compactação do solo; na profundidade 10-13 cm, quando foi utilizada a enxada rotativa, a grade de discos e a roçadora promoveram compactação do solo; na profundidade 25-28 cm, uma maior suscetibilidade à compactação foi promovida quando utilizou-se a roçadora.Editora UFLA2011-03-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/335Coffee Science - ISSN 1984-3909; Vol. 5 No. 2 (2010); 123-136Coffee Science; Vol. 5 Núm. 2 (2010); 123-136Coffee Science; v. 5 n. 2 (2010); 123-1361984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/335/pdfCopyright (c) 2011 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessAparecida dos Santos, Gislenede Souza Dias Junior, MoacirTácito Gontijo Guimarães, PauloSant’Anna Moreira Pais, Paula2013-02-24T13:55:25Zoai:coffeescience.ufla.br:article/335Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:37.694495Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |

The experiment was set up at the EPAMIG Experimental Farm in Patrocínio, Minas Gerais state, in a coffee field (Coffea arabica L.). The methods of weed control were: between the rows: rotary tiller, disk harrow, were mower and no weeding (control). In each management system, 15 samples were collected at 0-3, 10-13 and 25-28 cm depths (totalizing 315 samples) to generate the bearing capacity model both between the lines and in the traffic lines, except for the control treatment, where sampling was done only between the lines.
