This study investigates the effect of zinc (Zn²⁺) and copper (Cu²⁺) ion–based hydrogels on improving the biochemical parameters of essential oil–producing plants. Hydrogels were synthesized from biocompatible polymer matrices capable of absorbing and gradually releasing micronutrients in the root zone. The application of Zn- and Cu-enriched hydrogels enhanced plant growth, chlorophyll synthesis, and essential oil yield, while also increasing the activity of key antioxidant enzymes such as catalase and peroxidase. Compared to conventional fertilization methods, hydrogel-based micronutrient delivery significantly improved the biosynthesis of terpenoids and phenolic compounds, leading to higher essential oil quality and concentration. These results suggest that Zn- and Cu-based hydrogels can serve as an efficient and eco-friendly technology for optimizing the biochemical performance and productivity of aromatic and medicinal plants.
