The experiment was conducted in 2013. Research material included the leaves of a dandelion (Taraxacum officinale Weber ex Wigg.) – roots with the above-ground part, gathered before tying of flower baskets (Taraxaci radix cum herba). Laboratory analyses, which were the continuation of the pot experiment, were conducted in the laboratory of the Department of Horticulture of the West Pomeranian University of Technology in Szczecin. In the dried plant material (dandelion leaves) the content was determined: of dry mass and total ash, vitamin C as L-ascorbic acid, chlorophyll a, b and total, total carotenoid and antioxidant activity. Based on the obtained results it was found that both the biometric features of the dandelion plants and their biological value subjected to significant changes depending on the amount of copper contained in the soil and the crop harvest date.
