Resumo: | In this work, soil properties and least limiting water range (LLWR) were determined for an Alfisol under three states of compaction with black beans crop. Three experiments were used, comprising the following treatments: 12 years of no-tillage NT; 12 years, of no-tillage compacted by four passes of a bucket loader NTc; and chiseling of soil previously under no-tillage for 12 years Ch. Throughout the plant cycle, bulk density, total porosity, volumetric water content, air filled porosity and soil resistance to penetration were evaluated. Plant root distribution and yield were also evaluated. The critical bulk density obtained by LLWR was 1.75 Mg m-3. In the NTc the bulk density was higher than critical value for most soil layers, whereas the PD and Ch presented higher value in a few layers. Soil water content was out of LLWR range for most part of plant cycle. Soil resistance to penetration in the NTc was higher than critical value in all evaluated dates, while in roots concentrated superficially. For the three experiments, higher compaction levels (NTc) induced yield reduction from 30 to 62% and soil chiseling (Ch) induced yield reduction from 2 to 12% compared to crops under no-tillage (PD). Compaction alleviation by chiseling was not necessary to improve crop yield for soil physical conditions of this area. |

Foram utilizados três experimentos, cujos tratamentos constituíram-se de: plantio direto (PD); plantio direto compactado pelo tráfego de quatro passadas de máquina (PDc); e escarificação em área anteriormente sob plantio direto (Esc). Avaliaram-se a densidade, a porosidade, a umidade volumétrica e a resistência à penetração do solo. Nas plantas, avaliaram-se a distribuição do sistema radicular e a produtividade. A densidade crítica obtida pelo IHO foi de 1,75 Mg m-3. No PDc a densidade do solo foi superior à crítica na maioria das camadas, enquanto o PD e Esc apresentaram densidade acima da crítica em poucas camadas. A umidade do solo ficou fora dos limites do IHO na maior parte do ciclo da cultura. A resistência à penetração ficou acima da crítica no PDc em todas as avaliações. O sistema radicular concentrou-se superficialmente no PDc com melhor distribuição e desenvolvimento no PD e Esc. Nos três experimentos, a produtividade do Esc foi de 2 a 12% menor, e a do PDc foi de 30 a 62% menor do que no PD. A escarificação não foi necessária para as condições físicas do PD.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCollares, Gilberto LoguércioReinert, Dalvan JoséReichert, José MiguelKaiser, Douglas Rodrigo2006-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7330Pesquisa Agropecuaria Brasileira; v.41, n.11, nov. 2006; 1663-1674Pesquisa Agropecuária Brasileira; v.41, n.11, nov. 2006; 1663-16741678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7330/4375info:eu-repo/semantics/openAccess2014-10-06T18:24:45Zoai:ojs.seer.sct.embrapa.br:article/7330Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-06T18:24:45Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
