title: Copper for crop nutrition
abstract: Copper (Cu) is a transition redox-active metal, one of eight essential trace elements and one of 17 essential elements required by humans, animals, and plants in limited ranges of low concentrations. Copper exists in two oxidation states, Cu⁺ and Cu²⁺. This property makes copper a key structural component and catalytic cofactor in many metalloproteins. These include enzymes involved in photosynthesis, respiration, stress protection, and lignin metabolism. Plant genomes contain an average of more
