Experimental studies on the decontamination and stabilization of sludge were carried out using the product “Desolak”, which is calcium oxide treated with a disinfectant. As a result of the research, it was found that the sewage sludge of Voronezh is safe and can be used as organic fertilizer for growing agricultural plants. The determination of the content of mineral nutrients in the soil and the soil reaction showed that the application of organic fertilizers in the form of sludge in comparison to the variant without fertilizers increases the content of nitrogen nitrate, exchange potassium, and mobile phosphorus in the soil. At the same time, the mass fraction of impurities of toxic elements in the soil decreases when sewage sludge is added as an organic-lime fertilizer.
