Resumo: A typic soil of the sugarcane region of Campos, RJ, (Typic Paleudult) was incubated with increasing volumes of stillage (equivalents to 0, 50, 100, 150, 200 and 400 m3/ha) with and without additon of N and P and was leached, in leaching columns, with volumes of water equivalent to 1, 2 and 3 volumes of soil pores. For the treatments without NP, the phosphate contents of the effluents did not show any practical difference for the three leaching volumes. For the treatments with NP, the phosphate contents of the effluents, for each leaching volume, tended to decrease as the applied volumes of stillage increased. Phosphate leaching practically ceased al the dose of stillage equivalent to 400 m3/ha.

Após incubação do solo com doses crescentes de vinhaça, (equivalentes a 0,50, 100, 150, 200 e 400 m3/ha), na presença e ausência de N e P, efetuou-se sua lixiviação, em colunas de percolação, com volumes crescentes de água, equivalentes a 1, 2 e 3 volumes-poros. A lixiviação das colunas de solo tratado com doses crescentes de vinhaça sem NP praticamente não apresentou diferença nos teores de fosfato nos efluentes resultantes da percolação com crescentes volumes de água. Nos tratamentos que receberam vinhaça complementada com NP, os teores dê fosfato lixiviados, para cada volume-poro percolado, tenderam a decrescer à proporção que foram aumentadas as doses de vinhaça aplicadas ás amostras de solo. No ponto equivalente à dose de 400 m3/ha de vinhaça complementada com NP, a lixiviação de fosfato praticamente cessou.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLeal, Jair R.Nunes, Marcos B.Velloso, Ary Carlos X.2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15585Pesquisa Agropecuaria Brasileira; v.17, n.2, fev. 1982; 177-180Pesquisa Agropecuária Brasileira; v.17, n.2, fev. 1982; 177-1801678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15585/9579info:eu-repo/semantics/openAccess2014-04-16T12:24:16Zoai:ojs.seer.sct.embrapa.br:article/15585Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T12:24:16Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
