Description:	Trace metals phytoavailability is a major concern related to land application of biosolids. Formation of soluble complexes between metals and organic acids exudates in the rhizosphere b plants or produced by microbial activity seems to play an important role on trace metals phytoavailability (Mench & Martin, 1991; Marschner, 1995). The present study was carried out; i)to determine organic acids present at the rhizosphere of different plant species cultivated in the presence or absence of biosolids; and ii) to assess the correlation between production of organic acids and the shoot content of trace elements.
