Benefits of Copper

Copper (Cu) is part of the composition of some oxidation and reduction enzymes in plants. It is an essential element in chlorophyll formation and has an active role in the photosynthesis process.

  • - Its presence in sufficient quantity in the plant limits the toxicity of micronutrients such as zinc and manganese.
  • - It plays a role in nitrogen metabolism within the plant, as it has a major role in protein formation, so the absorbability of copper increases in the presence of amino acids.
  • - It has a fundamental role in enhancing the plant's immune system against many fungal diseases.

Symptoms of Copper Deficiency in Plants

  • Paling and curling of new leaves followed by wilting of leaf edges.
  • Reduced pollen viability leading to fewer fruit set flowers.
  • Occurrence of dieback in branches.
  • In citrus, juice content inside fruits decreases, especially in lemons.
