Supplementation of the basal diet with Fe increased Fe concentration in egg. Concentration of Zn, Fe and Cu in excreta were related to their dietary content. Concentrations of Zn, Fe and Cu in herbage correlated significantly with the supply of these elements by hen excreta into soil. The Zn supplied by hen excreta was more stable than Fe and Cu; thus Zn could accumulate in the soil.
