A greenhouse experiment was conducted to determine the effects of urban sewage sludge that is applied to soil,on the plant nutrients and heavy metal contents in the fruits and the leaves in strawberry.Strawberry plants were grown in pots containing different amounts of sewage sludge (corresponding to 0,15,30 and 60 T/ha,as dry weight basis).In the applications of sewage sludge,higher mineral contents and heavy metal accumulation were determined both in the fruits and the leaves.Sewage sludge applications have important effects on N,P,K,Ca,Mg,Fe,Zn,Mn,Cu,,Pb,Ni,Cd and Cr contents in the leaf.It is observed that when the application level is increased,mineral contents and heavy metal accumulation are also increased.
