Abstract

According to the research results, the most significant impact on the change in the physicochemical properties of the meadow-chernozem soil was exerted by the complex aftereffect of the ameliorative norms of urban sewage sludge with zeolite-containing agricultural ore. The cation exchange capacity against their background was higher than the initial one by 4.76-5.59 mg-eq/100 g of soil, the sum of exchangeable bases by 6.37-7.51 mg-eq/100 g of soil.
