Resumo: | In 1993, it was evaluated the compaction of a Planosol (Albaqualf) submitted to different tillage systems, measuring soil density through the volumetric ring method, in three layers. Treatments consisted of six tillage systems selected from an experiment conducted at Embrapa-Centro de Pesquisa Agropecuária de Clima Temperado, Pelotas, RS, Brazil, since 1985. High soil density values were obtained; in the first layer (0-10 cm), the no-tillage rice cultivation on the rye-grass straw was the system with the lowest value. The systems that involved more soil mobilization (rice continuous and rotation rice-soybeans-maize) resulted in higher soil density values compared to the reduced preparing systems (rye-grass x rice in zero tillage and soybean x rice in zero tillage). Compacted structures were identified in the intermediate layer (10-20 cm) in all tillage systems, except for the rotation rice-soybean-maize, where soil density differences were not detected among soil layers. |

Os tratamentos consistiram de seis sistemas de manejo, selecionados de um experimento conduzido na Embrapa-Centro de Pesquisa Agropecuária de Clima Temperado, desde 1985. Observaram-se, de maneira geral, valores altos de densidade do solo; na primeira camada de solo (0-10 cm) o sistema que apresentou o menor valor foi o cultivo de arroz em plantio direto sob a resteva do azevém e nos sistemas que envolvem maior mobilização do solo (arroz contínuo e rotação arroz-soja-milho) os valores de densidade do solo foram maiores em relação aos sistemas de preparo reduzido do solo (azevém x arroz plantio direto e soja x arroz plantio direto). Ocorreu maior compactação, em relação à primeira camada, na camada intermediária (10-20 cm), em todos os sistemas de cultivo, exceto no sistema de rotação arroz-soja-milho, no qual não houve diferença de densidade entre as camadas de solo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPedrotti, AlceuPauletto, Eloy AntonioGomes, Algenor da SilvaTuratti, Ariovaldo LuisCrestana, Silvio2001-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6187Pesquisa Agropecuaria Brasileira; v.36, n.4, abr. 2001; 709-715Pesquisa Agropecuária Brasileira; v.36, n.4, abr. 2001; 709-7151678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6187/3252info:eu-repo/semantics/openAccess2010-08-09T12:48:46Zoai:ojs.seer.sct.embrapa.br:article/6187Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-09T12:48:46Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
