Resumen:
The presence of trace elements in water and soils, their absorption by plants, and their transfer to the food chain, is a phenomenon that is being studied in different regions around the world.  In Argentina, few studies exist regarding trace element content in soils, and the studies on forages are furthermore scant.  The interest to quantify the levels of trace elements in cattle forage lies in the intrinsic connection between the quality of forage and the nutritional and toxicological aspects of the meat for human consumption.  The aim of this work was to evaluate the enrichment of Cu and Zn in ryegrass (Lolium perenne) fertilized with excrement from feedlots.  The obtained results demonstrate differences in Cu and Zn concentrations between the fertilized and non-fertilized reactors.   There were no differences found in the Cu and Zn concentrations considering the method of fertilization (homogenization or superficial).
