Perco plant can grow normally on leached smolnitsa treated with sewage sludge in amounts 1 to 15% of sludge to the soil. In these limits the heavy metals content in the vegetative mass is low is far bellon the stress concentration. The vegetative mass of the variants with sludge addition is higher as compared to that of the control, but is lower in comparison with that of the variants with higher mineral fertilization only. Increased amounts of nitrogen and phosphorous fertilizers have to be used with the higher amounts of sludge, which will improve the plant material nutrition potential of the plant material.
