Resumo: | The Latosols of the Cerrados of the Central highlands of Brazil are chemically poor and therefore require large applications of lime and phosphorus to become productive. They also have physical problems as low clay activity and low water availability for most crops. Although soil organic matter content is reasonable and ranges from 2.5 to 3.0%, soil management practices are needed to counteract the rapid decline in organic matter content and the negative effects on the chemical and physical properties of the soil that are observed soon after the soil is cultivated. Therefore an study was conducted to test the effects of incorporation of "mucuna preta" (Styzolobium atterimum, Piper & Tracy); "mucuna preta" + sorghum; corn: soybean and sorghum at two fertility levels on some properties of the soil like: water holding-capacity, water availability, bulk density and total porosity. Also the effects of the incorporation of the materials on corn production planted in the following cropping season were evaluated. Results indicated that soon after incorporation of the crop residues, water holding-capacity and availability decreased. The effects was inversaly proportional to the quantity of dry matter added and to its C/N ratio. Soil organic matter levels decreased in all treatments after incorporation of the materials. It was observed a declining tendency of the bulk density and total porosity values which may be caused by the decomposition and rearrengement of the soil organic matter. The incorporation of "mucuna preta" and soybean at the highest fertilizer level resulted in the largest corn production. |

Estes solos tem também alguns problemas físicos, como baixa atividade de argila e baixa disponibilidade de água para a maioria das culturas. Embora o teor médio de matéria orgânica desses solos variando de 2,5 a 3,0% seja razoável, técnicas de manejo são necessárias para controlar o rápido declínio do teor de matéria orgânica e seus efeitos negativos nas propriedades físicas e químicas do solo que é observado logo após o seu cultivo. Neste experimento foram testados os efeitos da incorporação da mucuna preta (Styzolobium atterrimum, Piper & Tracy); mucuna preta + sorgo; milho; soja e sorgo em dois níveis de adubação, sobre algumas propriedades físicas do solo, tais como: capacidade de retenção de água, disponibilidade de água, densidade aparente e porosidade total. Também os efeitos dessas incorporações na produção de milho plantado no ano agrícola seguinte e usado como cultura indicadora foram avaliados. A curto prazo, houve decréscimo na capacidade de retenção e na disponibilidade de água após a incorporação de todos os tratamentos estudados. Este decréscimo foi inversamente proporcional à quantidade de matéria seca e à relação C/N dos materiais incorporados. Para todos os tratamentos os teores de matéria orgânica foram diminuídos após a incorporação. Os valores da densidade aparente e porosidade total em todos os tratamentos tenderam a diminuir principalmente em virtude da decomposição e reorganização da matéria orgânica do solo. Os restos culturais de mucuna e soja, em um melhor nível de adubação química, proporcionaram as melhores produções de milho.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraResck, Dimas V.S.Pereira, João2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17113Pesquisa Agropecuaria Brasileira; v.16, n.6, jun. 1981; 801-807Pesquisa Agropecuária Brasileira; v.16, n.6, jun. 1981; 801-8071678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17113/11430info:eu-repo/semantics/openAccess2014-04-15T19:45:00Zoai:ojs.seer.sct.embrapa.br:article/17113Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:45Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
