Resumo: By the results obtained from soil samples of the Zona da Mata region in Pernambuco State, Brazil, correlations between pH values and base saturation were established. Such results provided a wide range of values for base saturation: -8.59 to 88.29%, for pH (H 20): -4.0 to 6.5, and finally, for pH (CaCl 2 0.01M): between 3.5 to 6.1. The linear regression equations derived from the adjusted data associated to the proposal changes in one of the recommended procedures for lime requirements allowed the estimate of the amount of CaCO3 necessary for a given base saturation value, taking into account only the pH and the sum of bases.

Tais resultados variaram, para a saturação de bases, de 8,59 a 88,29%, enquanto as leituras para o pH-H2O ficaram compreendidas entre 4,0 e 6,5, e para o pH-CaCl2 0,01M, entre 3,5 e 6,1. As equações de regressão linear ajustadas aos dados, juntamente com as modificações propostas a um dos critérios de calagem em uso, tornaram possível a estimativa da quantidade de CaCO3 requerida para se obter uma dada saturação de bases, em função, apenas, do pH e da soma de bases.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCavalcanti, Francisco José de Albuquerque2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13476Pesquisa Agropecuaria Brasileira; v.25, n.4, abr. 1990; 641-645Pesquisa Agropecuária Brasileira; v.25, n.4, abr. 1990; 641-6451678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13476/7584info:eu-repo/semantics/openAccess2014-04-17T14:30:52Zoai:ojs.seer.sct.embrapa.br:article/13476Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T14:30:52Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
