“…The results of organic carbon in applying a combination of fertilizers give low yields due to reducing nutrient levels due to microbes. The low organic carbon in the soil is caused by the immobilization factor or the process of reducing the amount of nutrient content caused by microbial activity [17,18].…”

“…The SS application has a positive effect on carbon mineralisation in various soil types, climatic regions, cropping systems and land uses. It plentifully releases mineral elements and improves the physical, chemical, and biological parameters of the soil, which benefits from an increased gas exchange, better water infiltration and retention (Boudjabi & Chenchouni, 2021).…”

Topicality. The events of recent years (the Covid-19 pandemic, hostilities in Ukraine) have led to a significant increase in world food prices. Thus, the FAO price index in February 2022 reached a historic high of 140.7 percentage points. One of the significant factors in this situation is a significant increase in prices for fertilizers for agriculture, which leads to their shortage. This actualizes the search for a solution to the problem of using sewage sludge as biological resource for sustainable agriculture and ensuring the implementation of sustainable development goals, including goals 2, 6, 11, 12, 15.Aim and tasks. The purpose of the article is to analyze various aspects of the use of sewage sludge in agricultural production as one of the promising ways to achieve sustainable development goals.Research results. The content of organic matter in the sludge can improve the physical, chemical, and biological properties of the soil by ensuring better soil cultivation and water retention capacity, especially when dehydrated sewage sludge is used. Biosolids reduce runoff and increase surface water retention. Organic nitrogen in sludge is much less likely to cause groundwater pollution than chemical nitrogen fertilizers. The use of sewage sludge on agricultural land is the best way to recycle the nutrients it contains. Sewage sludge can therefore be considered an important biological resource for sustainable agriculture. Physico-chemical characteristics of sewage sludge of different origin were compared. The concentration of carbon, nitrogen, and phosphorus were similar. Nevertheless, there are some site-specific factors that make each sewage sludge unique and must be taken into account to predict the outcome of sewage sludge treatment. To achieve the goal, an analysis was made of the effect of sewage sludge on the physico-chemical and microbial properties of the soil; its impact on plants and their productivity; the problems of using soil sludge in agriculture, taking into account its contamination with various substances (heavy metals, microplastics and pharmaceuticals), have been studied.Conclusions. Sewage sludge is a promising fertilizer for sustainable agriculture, taking into account the need for an effective technology for its purification from hazardous substances.

“…Application of sewage sludge to agricultural fields is one of the preferred solutions for addressing this problem . Its high organic matter content, minerals, and nutrients composition have shown a positive effect in correcting deficiencies in agricultural soils, reducing the need for inorganic fertilizers, and contributing to a circular economy model. − However, there are concerns about the potential risks for soil and public health that result from this practice, since sewage sludge can contain a wide range of toxic contaminants …”

Sewage sludge valorization in agricultural fields is in many countries a circular economy strategy to handle the disposal issues of this complex residue. Many countries regulate the content of heavy metals and other agrochemical parameters in sewage sludge, establishing threshold limits for its application in agricultural fields. This requires the employment of robust, timesaving, and cost-effective analytical tools suitable for multielemental analysis at trace levels. Inductively coupled plasma optical emission spectrometry (ICP-OES) is a powerful instrumental technique with proven success in this field. In this laboratory experience, students perform a multielemental analysis of sewage sludge samples, by sample acidic digestion in a closed microwave system followed by ICP-OES analysis. Validation of the analytical method is also proposed, evaluating the linear response of an external calibration with internal standardization and using a certified reference material for evaluation of recovery and precision. The method is to be applied to a real sewage sludge sample to assess its nutrient content and to compare levels of heavy metals with enforced regulations. This work was successfully carried out in an analytical chemistry class with undergraduate students of chemical, environmental, and bioengineering bachelor degree courses. Most students reached the proposed learning goals, obtaining good or very good classifications in all evaluated parameters in the assessments of laboratory performance and final group reports.
