| dc.description | The resorption of nutrients of dominant species in a successional sequence of forests of the Argentinean Mesopotamian Espinal was studied for two years (2009-2010). The aim was to compare nutrient resorption (nitrogen, phosphorus, potassium, calcium, magnesium and sulphur) among species of the Fabaceae ( Acacia caven , Prosopis affinis and Prosopis nigra with the capacity of biologically fixing the atmospheric nitrogen) and Celtidacea families ( Celtis tala , without the capacity of biologically fixing the atmospheric nitrogen). Samples of mature leaves (collected in spring) and senescent leaves (collected in autumn) were chemically analyzed to determine nutrient concentration; afterwards, resorption rates were calculated ( Rc 1 and Rc 2 ). It was found that the higher nitrogen resorption was associated with the inability of biologically fixing the atmospheric nitrogen, having both indexes a maximum nitrogen resorption in C. tala and a minimum in A. caven . On the contrary, the other elements (P, K, Ca, Mg and S) showed resorption differences in one of the indexes used, indicating a higher resorption in Fabaceae in contrast with Celtidaceae, associated with a higher foliar demand of these elements. | |
