Perfil mineral en los pastizales de Andropogon lateralis y Sorghastrum setosum (Gramineae) en Corrientes, Argentina

Abstract

El objetivo de este trabajo fue determinar la composición florística y el aporte de minerales a la dieta animal para la producción de carne bovina de los pastizales de Andropogon lateralis Nees (PAL) y Sorghastrum setosun (Griseb.) Hitchc. (PSS), analizados mediante espectrometría ICP-AES en dos series de suelo de la provincia de Corrientes, Argentina. El mayor aporte de materia seca lo realizan A. lateralis y S. setosum . El aporte de leguminosas es bajo. El perfil de elementos minerales esenciales, probablemente esenciales y los de función incierta, cubren parcialmente los requerimientos del ganado bovino productor de carne, excepto para Mn. Las relaciones entre elementos, Ca/P, Na/K (mEq), Cu/Mo y Cu/Fe son aceptables. Las relaciones K/Mg, K/Ca+Mg (mEq) y Na/Mg (mEq) no son adecuadas, pues existe deficiencia de Mg.

The goal of this work was to determine the floristic composition and the mineral contribution of Andropogon lateralis Nees (PAL) and Sorghastrum setosum (PSS) pastures, in the animal diet for the production of beef, analyzed by ICP-AES spectrometry in two series of soils from the Province of Corrientes, Argentina. The greatest contribution of dry raw matter is provided by A. lateralis and S. setosum. The contribution of legume is low. The profile of essential mineral elements, probably essential ones and of those of uncertain function, partially fulfill the meat producer cattle requirements. The elemental ratios Ca/P, Na/K (mEq), Cu/Mo and Cu/Fe, are acceptable. The K/Mg, K/Ca+Mg (mEq) and Na/Mg (mEq) ratios are not adequate, and there is Mg deficiency.
