QUELAFERT® COBRE

Copper chelates (EDTA)

Copper chelate in the form of dispersible microgranules designed to prevent or correct copper deficiencies in woody or herbaceous crops. Copper acts as a catalyst in numerous physiological processes in the plant:

  1. It is part of many proteins.
  2. It is present at various stages of the photosynthesis process.
  3. Promotes nitrogen utilisation and protein synthesis.

Copper is a low mobility element, being fixed to the soil. This fixation increases in soils rich in organic matter, clayey soils or soils with a high phosphate content. Furthermore, soils with an excess of lime or a rise in pH reduce its assimilation by the plant.

As the copper is chelated by the supplementing agent EDTA, we ensure that the copper is in a form that can be assimilated by the plant. Deficiencies in this element are first visible in the young tissues, due to their low mobility.

The symptoms are: whitish or pale yellow discolouration of the leaf tips, lack of turgidity and even necrosis. Older leaves have dry tips. All this results in a decrease in yield quality.

Stability range of copper chelate is at pH: 4 – 9.
