The Soil Contamination with Cadmium after Applications of Sewage Sludge
Original language description
An immediate issue of city sewage plants is to find an efficient, safe and low-cost method of sewage sludge disposal. One option is to use the sludge to fertilise and reclaim agricultural land. The target of this article is to identify the effect of stabilised, hygienic and safe sewage sludge applications on biomass growth of poplars and on changes in the level of cadmium in the soil. Soil analyses showed that the cadmium content did not change considerably after sewage sludge use. Detected cadmium amounts are markedly below the limit estimated for application on agricultural soil (1 mg kg-1 of soil). Increasing doses have a positive effect on biomass growth of poplars. Considering these facts there is good reason to use stabilised and hygienically safe sewage sludge for fertilisation in plantations of energy tree species. In this way the sludge is effectively used in the process of biological recycling.
