Resumo: The agricultural use of urban waste compost is an alternative for a better technician-scientific-economic viability, because this organic residue is a source of nutrients and organic matter. This study was carried out in greenhouse conditions in order to evaluate the temporal availability, by Mehlich-1 extractor, of Cd, Co, Cr, Ni, and Pb in five types of soils incubated with 0, 25, 50 and 100 Mg ha-1 of waste compost during 0, 16, 32, 64 and 150 days. Most of the heavy metals had its availability reduced at the beginning of incubation. The availabitily of heavy metals was dependent of the soil texture, pH and content of soil organic matter. The application of the highest doses of waste compost can result in risks of soil contamination mainly in the Oxisol, Mollisol and Alfisol, with periods from 6 to 12 months for reduction of heavy metal availability.

Este estudo, realizado em casa de vegetação, teve como objetivo avaliar a disponibilidade temporal dos metais pesados Cd, Co, Cr, Ni e Pb, por meio do extrator Mehlich-1, em cinco tipos de solos, incubados com 0, 25, 50 e 100 Mg ha-1 de composto de lixo, em períodos de 0, 16, 32, 64 e 150 dias. A maioria dos metais pesados teve sua disponibilidade reduzida nos primeiros períodos de incubação, sendo esse efeito dependente de textura, pH e teor de matéria orgânica do solo. O uso continuado de composto de lixo, principalmente nas doses mais elevadas, pode resultar em riscos de contaminação do ambiente pelo efeito cumulativo, em especial nos solos Latossolo Vermelho-Amarelo distrófico, Chernossolo Háplico órtico e Nitossolo Vermelho eutroférrico, cujo período para redução da disponibilidade dos metais pesados varia de 6 a 12 meses.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilva, Fábio Cesar daSilva, Carlos AlbertoBergamasco, Alessandra FabíolaRamalho, André Luís2003-03-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6578Pesquisa Agropecuaria Brasileira; v.38, n.3, mar. 2003; 403-412Pesquisa Agropecuária Brasileira; v.38, n.3, mar. 2003; 403-4121678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6578/3635info:eu-repo/semantics/openAccess2010-08-16T19:33:14Zoai:ojs.seer.sct.embrapa.br:article/6578Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-16T19:33:14Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
