Resumo: The influence of green manure residues addition in the dynamic of ions in acid soils is not well known. In this study, ion mobility in a sample of the Bw horizon of an Dark-Red Latosol (Oxisol), leached with citric and succinic acid pure solutions and with aqueous residue extracts of black oats (Avena strigosa) and oil seed radish (Raphanus sativus) were evaluated in soil columns (5, 10, 20, and 40 cm long by 4 cm diameter). After the solutions and extracts passed through the soil columns, the following parameters were determined: solubles contents of Cas, Mgs, Ks, Alst (total), Also (organic), Alsm (monomeric) and dissolved organic carbon. In soil, the parameters evaluated were the exchangeable contents of Caex, Mgex, Kex, and Alex and pH (CaCl2). Citric and succinic acids increased Alst and Cas contents, respectively, resulting in decreasing exchangeable fractions of these elements in soil. Black oats extract was more effective to extract Caex and oil seed radish to extract Alex. The decrease in Caex and Alex was followed by an increase in Kex. Organic complexes formed with low molecular organic ligands and Cas and Alex were suggested to play a role in the mobility of ions in subsoils of acid soils after the addition of both crop residues extracts and pure organic acid solutions.

Neste estudo, a mobilidade de íons em amostra do horizonte Bw de um Latossolo Vermelho-Escuro álico lixiviado com soluções puras de ácidos cítrico e succínico e extratos aquosos de resíduos de nabo forrageiro (Raphanus sativus) e aveia-preta (Avena strigosa) foi avaliada em colunas de solo (5, 10, 20 e 40 cm de altura por 4 cm de diâmetro). Após a percolação das soluções e extratos pelas colunas de solo determinaram-se, nas soluções efluentes, os teores de Ca (Cas), Mg (Mgs), K (Ks), Al total (Alst), orgânico (Also), monomérico (Alsm) e carbono orgânico dissolvido. No solo, foram determinados os teores trocáveis de Ca (Catr), Mg (Mgtr), K (Ktr) e Al (Altr) e o pH (CaCl2). Os ácidos cítrico e succínico aumentaram os teores de Alst e Cas, respectivamente, causando reduções nas frações trocáveis desses elementos no solo. O extrato de aveia-preta foi mais efetivo na remoção do Catr e o de nabo forrageiro na do Altr. O decréscimo de Catr e Altr foi seguido do aumento do Ktr. A formação de complexos entre Cas e Altr com compostos orgânicos de baixo peso molecular foi sugerida como o provável mecanismo responsável pela mobilidade dos íons polivalentes no subsolo de solos ácidos após a aplicação dos extratos de resíduos vegetais e das soluções puras de ácidos orgânicos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFranchini, Júlio CezarMiyazawa, MarioPavan, Marcos AntonioMalavolta, Euripedes1999-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5562Pesquisa Agropecuaria Brasileira; v.34, n.12, dez. 1999; 2267-2276Pesquisa Agropecuária Brasileira; v.34, n.12, dez. 1999; 2267-22761678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5562/2753info:eu-repo/semantics/openAccess2010-06-29T16:54:10Zoai:ojs.seer.sct.embrapa.br:article/5562Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-06-29T16:54:10Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
