Abstract

The article examines the prospects and technologies for the use of sewage sludge masses (SSM) in agriculture, as well as the environmental and economic aspects of their utilization. It highlights potential risks associated with the presence of heavy metals and pathogenic microorganisms, which may pose threats to the environment and human health. The paper provides an analysis of current approaches to the processing and utilization of sewage sludge, aimed at reducing environmental impact. A review of current regulatory frameworks governing the use of sewage sludge in Ukraine and other countries is presented. Based on the research findings, the paper emphasizes the feasibility of scientifically justified application of SSM as an economically viable and environmentally acceptable resource in sustainable agriculture systems. An agrochemical analysis of SSM from sedimentation maps (wet) and dry storage (heaps) was conducted. It was shown that the concentration of heavy metals does not exceed maximum permissible limits. The importance of using SSM in the cultivation of cereal crops (wheat and barley), legumes (soybean), pseudocereals (buckwheat), and industrial crops (sunflower, corn for grain) is noted, which corresponds with the focus of our research.
