“…Vasilyev et al [52] found that application of WTRs to loamy brown earth soil decreased the nutritional content (K and starch) of potatoes grown in that soil due to immobilisation of potassium, while at the same time the soil nutrient (organic matter, total P, and total K) content increased. These effects appear to have been due to variations caused in soil chemical stoichiometry by sludge application.…”

Water Treatment Residuals (WTRs) are a by-product of the addition of chemical coagulants to water during the water treatment process and are a mixture of water and organic and inorganic matter that coagulates during the treatment process. WTRs often contain metals such as iron, aluminium, and manganese that have been oxidised as part of the process or are constituents of the coagulation chemicals used. The metals within WTRs are of interest with regard to applying these sludges to agricultural land. WTRs can also contain beneficial organic matter and nutrients (primarily nitrogen). The nature of the benefits delivered is largely dependent on the quality of the raw water and these beneficial components are generally found in much smaller quantities in WTRs than are found in sewage sludge produced from wastewater. However, WTRs can still be used to enhance the physical properties of soils. As urban populations increase in size, it is anticipated that the tonnage of WTRs will increase significantly in the future. At present, the majority of WTRs are disposed of in landfills; however, landfill charges are increasing significantly, making disposal of an increasing tonnage of WTRs financially unviable. In terms of a circular economy, the procedure of reusing WTRs for alternative applications satisfies the Scottish Government’s goals in terms of waste prevention and reducing the amount of material being sent to landfill as set out in the Proposals for Legislation in 2019. Given the potential benefits in terms of cost savings and compliance with government legislation, and the complexities of understanding where and when WTRs can be used in land applications, we developed a Decision Support Tool (DST) that uses data obtained from an extensive review of approaches in other countries to assist in decision making. We also conducted a pre-application analysis and provided guidance on when and where WTRs can be used in land applications and when they are not suitable, presented in a simplified format that requires few inputs from the user in order to simplify the process and removes the requirement for a specialist operator during pre-application analyses.

“…The fact of obtaining high yields of agricultural crops with expanded reproduction of soil fertility is indisputable, namely, the introduction of mineral and organic fertilizers in doses exceeding the needs of agricultural crops. In the process of vegetation of plants, especially at the initial stages of crop formation, the use of high rates of nitrogen fertilizers leads to the accumulation of nitrates in agricultural products, which reduces the quality of crop production [1].…”

The paper considers the issues of preserving and expanding the reproduction of soil fertility for obtaining high yields of agricultural crops, identifies ways to solve the problem of ecologizing the agricultural landscape by introducing horny hoofed crumbs as an alternative to the mineral form of nitrogen fertilizer and zeolite-containing tripoli as a sorption-type soil improver, as in direct action, and aftereffect. The results of the study revealed the role of the applied fertilizers in increasing the leaf surface area of potato and fodder beet plants, led to an increase in the biological activity of the soil, contributed to the improvement of the quality indicators of the obtained products (dry matter content, nitrates), increased the productivity of cultivated row crops, as in the year of fertilization and endured, and in the aftereffect on barley. The conducted bioenergetic assessment of the studied fertilizers and zeolite-containing tripoli against the background of phosphorus-potassium mineral fertilizers determined the most effective options with the use of horn-hoofed crumbs and tripoli, both independently and when applied together.
