Resumo: | The effect of five phosphates as sources of phosphorus for soybean (Bragg cultivar) was evaluated in two rates (100 and 200 kg/ha of total P2O5), on limed and unlimed soil conditions. The experiment was carried out under field conditions, during the soybean growing season of 1973/74, 1974/75, 1975/76 and 1976/77, at UEPAE Pelotas station. The pH and the exchangeable Ca + Mg content from the soil were increased with Gafsa phosphate, but mainly with lime, Thomas slag and Yoorin thermophosphate application. The exchangeable Al content was eliminated by lime application and decreased annually by application of Gafsa phosphate, Thomas slag and Yoorin thermophosphate, when the lime was not applied. Thomas slag and Yoorin thermophosphate were the best phosphates for grain yield and do without lime: however, under limed soil conditions all phosphates had some efficiency, except for the Gafsa phosphate in the first growing season. |

Bragg) em campo nativo localizado na UEPAE de Pelotas, durante as safras de 1973/1974, 1974/75, 1975/76 e 1976/77. O pH e o teor de Ca + Mg trocáveis do solo aumentaram com a aplicação do fosfato-de-gafsa e, principalmente, do calcário, da escória-de-thomas e de termofosfato-de-yoorin. O Al trocável foi eliminado pela calagem e, na ausência desta, diminuiu anualmente com o emprego do fosfato-de-gafsa, da escória-de-thomas e do termofosfato-de-yoorin. Os resultados de rendimento de grãos mostraram que a escória-de-thomas e o termofosfato-de-yoorin tiveram o melhor desempenho, podendo dispensar a calagem. No entanto, com a calagem, todas as fontes apresentaram eficiência semelhante, exceto o fosfato-de-gafsa no primeiro ano.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMachado, Mauri OnofreVianna, Antonio Carlos TorresCasalinho, Helvio Debli2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15349Pesquisa Agropecuaria Brasileira; v.18, n.7, jul. 1983; 721-727Pesquisa Agropecuária Brasileira; v.18, n.7, jul. 1983; 721-7271678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15349/9216info:eu-repo/semantics/openAccess2014-04-16T18:59:42Zoai:ojs.seer.sct.embrapa.br:article/15349Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:59:42Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
