Impact of composts produced on the basis of sewage sludge on the zinc and cadmium contents in the soil reclaimed
A degraded soil was reclaimed by addn. of lime and composts (3-9%) consisting of sewage sludge and power plant ash. The soil was studied twice for Zn, Cd and org. C content directly and after 10 years. The ay. metal contents 45.12 and 0.313 mg/kg, rasp., met the environmental requirements for workable soils. The org. matter-coupled metal fractions prevailed in both cases.
