Resumo: | Eleven soil profiles of the typical soils of the region known as "Zona Litoral-Mata" of the State of Pernambuco were studied. The amount of molybdenum in the surface horizons ranges from 2.13 to 0.06 ppm with an average of 0.90 ppm. Most of the soils are perfectly normal in respect of molybdenum content. The largest proportion of exchangeable molybdenum is found in the surfacial horizon, probably adsorbed by the soil organic matter. By taking into account the pH and the extractable molybdenum, the soils studied were classified into two groups: 1. Deficient soils and 2. Borderline soils. |

A concentração de molibdênio no horizonte superficial variou de 2,13 a 0,06 ppm com a média de 0,90 ppm. A maioria dos solos é perfeitamente normal quanto ao conteúdo de molibdênio. A maior proporção de molibdênio permutável se encontra no horizonte superficial, provavelmente adsorvida à matéria orgânica do solo. A consideração simultânea do molibdênio solúvel e do pH permite classificar os solos estudados em solos deficientes e solos no limite de deficiência.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraHorowitz, Arão2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16752Pesquisa Agropecuaria Brasileira; v.13, n.1, jan. 1978; 73-91Pesquisa Agropecuária Brasileira; v.13, n.1, jan. 1978; 73-911678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16752/11081info:eu-repo/semantics/openAccess2014-04-15T19:12:29Zoai:ojs.seer.sct.embrapa.br:article/16752Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:12:29Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
