Resumo: This study evaluated the effect of limestone Ca:Mg ratios on micronutrients in alfalfa. A randomized block design was used with five relations of Ca:Mg ratios (1:0, 1:1, 2:1, 3:1 and 4:1) at a recommended limestone dosage of 3,900 kg ha-1. An additional treatment was included at a ratio of 3:1 with the dosage of 7,800 kg ha-1. All treatments had four replicates in a six-cutting number, in 35 days of interval. The variables analyzed were: concentration and quantity of B, Cu, Fe, Mn, and Zn in dry matter. The decrease of the concentration of B, Fe, Mn and Zn was obtained in the treatment that used twice the recommended dosage. The antagonic effect between Ca, applied as CaCO3, and Cu was not observed in the treatments. The concentration of micronutrients varied according to the cutting times.

O objetivo deste trabalho foi avaliar o efeito da relação Ca:Mg do corretivo sobre micronutrientes na alfafa, em experimento conduzido em casa de vegetação, em um Latossolo Vermelho-Escuro distrófico. O delineamento experimental utilizado foi, em todos os tratamentos, inteiramente casualizado, com quatro repetições. Foram estudadas cinco relações (1:0, 1:1, 2:1, 3:1, 4:1, na dosagem equivalente a 3.900 kg ha-1), e um tratamento com a dosagem equivalente a 7.800 kg ha-1 (relação 3:1), em seis cortes, com intervalo de 35 dias. Verificou-se que o dobro da aplicação da relação 3:1 diminui significativamente os teores de B, Fe, Mn e Zn. A aplicação só de CaCO3, como corretivo da acidez, não afeta a absorção de Cu. Os teores dos micronutrientes estudados apresentam níveis considerados adequados, sendo, estes, afetados pelas épocas de corte.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMoreira, AdônisCarvalho, Janice Guedes deMoraes, Larissa Alexandra CardosoSalvador, João Odemir2000-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5991Pesquisa Agropecuaria Brasileira; v.35, n.10, out. 2000; 2051-2056Pesquisa Agropecuária Brasileira; v.35, n.10, out. 2000; 2051-20561678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5991/3095info:eu-repo/semantics/openAccess2014-08-19T19:52:53Zoai:ojs.seer.sct.embrapa.br:article/5991Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-19T19:52:53Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
