Our study focuses on obtaining and studying the properties of a complex consisting of humic acids and glycine. Through the analysis of quantitative data and theoretical approaches, we investigated the formation of complexes between humic substances and glycine, while also considering the current research status in the field of humic acid complexation. Furthermore, we utilized mathematical planning to determine the optimal conditions for activating brown coal from the Kenderlyk deposit using hydrochloric acid. The resulting complex of humic acids with glycine demonstrates promising applications in agriculture and can be effectively employed as a conventional plant fertilizer.
