Experimental studies on the decontamination and stabilization of sludge sites sediment with calcium oxide treated with disinfectant. The results of the research discovered that the sewage sludge of Voronezh City is safe and can be used as organic fertilizer for growing agricultural plants. Determination of the content of macro-elements of mineral nutrition in the soil and the reaction of its environment showed that the application of organic fertilizers in the form of sludge increases the amount of nitrate nitrogen, exchangeable potassium, mobile phosphorus in the soil compared to the non-fertilized sample. Contemporaneously, the mass fraction of impurities of toxic elements in the soil decreases when the sewage sludge is used as an organic-lime fertilizer.
