Optima Leaf-Cu+ is part of the Optima Leaf+ range, a product line of foliar fertilizers that are efficiently absorbed by crops. The ‘+’ indicates the presence of supplementary trace elements, which prevent unbalanced fertilization and demonstrably enhance the product's effectiveness.

Key functions of copper:

• Essential during seed and fruit formation.
• Necessary for chlorophyll formation and photosynthesis.
• Strengthens cell walls, leading to stronger and more flexible plant cells.
• Positively influences starch and sugar content, as well as the taste of fruits.
  

Possible causes of copper deficiency in plants

Low copper content in the soil.

• Soils with high organic matter content retain copper, reducing its availability to crops.
• Excessive phosphate and nitrogen in the soil hinder copper uptake by crops.
• A high soil pH reduces copper availability.
