Bright red, rather soft and tough heavy metal or element (Cu). The Latin name cuprum is derived from "aes cyprium" (ore from the island of Cyprus), where copper was extracted in ancient times. In nature, it is mostly found in minerals such as copper ore, chalcopyrite and copper glance. In all higher organisms, copper is an essential trace element as a component of many enzymes. As a nutrient, it is necessary for vine growth in small quantities, as it promotes the formation of chlorophyll, which is important for photosynthesis, and phytoalexins (growth substances). Copper deficiency is manifested by narrow pale green leaves, reduced shoot growth, shortened internodes and weak root formation.
