Resumo: This research was conducted for two years to evaluate magnesium fertilizer application (0, 24, 48 and 96 kg ha-1 year-1 of Mg) on a permanent pasture composed by Lolium perenne and Trifolium repens as an agronomic alternative of hypomagnesaemia management in grazing herds. The effect on magnesium, calcium, potassium and sodium concentration in the pasture dry matter and the ratio between cations were evaluated. The research was carried out on an Hapludand (Valdivia serie) with an initial available magnesium content of 0.8 cmolc kg-1. Pasture dry matter production was not affected by magnesium fertilization, nevertheless, the concentration of magnesium in the pasture dry matter increased proportionally to the magnesium applied. A weighed average showed an increase of 0.006 and 0.012 g kg-1 of dry matter for each kg of magnesium applied during the first and second year, respectively. In addition, the magnesium fertilization decreased the calcium dry matter concentration, but it did not affect potassium and sodium dry matter concentration. The ratios between calcium/magnesium, potassium/magnesium and sodium/magnesium decreased with the increase of the magnesium fertilization rate.

El ensayo se realizó en un suelo Hapludand (Serie Valdivia) con un nivel inicial de 0,8 cmolc kg-1 de Mg. No se detectó un efecto de la fertilización magnésica sobre la producción de materia seca de la pradera, pero la concentración de magnesio en la materia seca se incrementó proporcionalmente a la dosis de magnesio aplicada. Considerando el promedio ponderado anual el aumento de la concentración de magnesio fue de 0,006 y 0,012 g kg-1 de materia seca por cada kg de magnesio aplicado, durante el primero y segundo año, respectivamente. La fertilización magnésica disminuyó la concentración de calcio, pero no afectó la concentración de potasio ni de sodio en la materia seca del forraje cosechado. Las relaciones entre Ca/Mg, K/Mg y Na/Mg en general disminuyeron en la medida que aumentó la dosis de fertilización con magnesio.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBalocchi, OscarPinochet, DanteWittwer, FernandoContreras, PedroEcheverria, RodrigoGuzmán, Francisco2001-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6261Pesquisa Agropecuaria Brasileira; v.36, n.10, out. 2001; 1309-1317Pesquisa Agropecuária Brasileira; v.36, n.10, out. 2001; 1309-13171678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6261/3326info:eu-repo/semantics/openAccess2010-08-03T20:00:15Zoai:ojs.seer.sct.embrapa.br:article/6261Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-03T20:00:15Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
