Essential for nitrogen assimilation

Agro‑Cu is a liquid nutrient designed to prevent and treat copper deficiencies. Copper is indispensable to the functioning of enzymes responsible for the plant’s defense mechanisms against abiotic stresses. Copper is also essential for nitrogen assimilation and lignin synthesis in plant cell walls. Agro‑Cu is activated by Oligo® Prime, an innovative biostimulant technology that allows for quick absorption and translocation of nutrients and reinforces the plant’s natural defenses against abiotic stresses (drought, low temperature, salinity, etc.). Agro‑Cu can be applied to all crops based on soil or tissue analyses or as soon as deficiency symptoms appear. For more information on Agro‑Cu, consult your agronomic adviser.

Copper acts as a catalyst in many of the plant’s physiological processes, particularly in the transport chain of electrons occurring during photosynthesis (75% of the leaf’s total copper content is present in the chloroplast), the synthesis of lignin in cell walls, oxidation reactions of ascorbic acid, cellular breathing, and in pollen vitality and fertility. In cases of copper deficiency, one observes a global metabolic dysfunction of the plant and stunted growth.

Copper activates the transformation of nitrates absorbed in the process of protein synthesis. The result of its action translates into an increase in proteins. A good supply of copper allows the plant to improve its natural ability to defend against many adverse actions or conditions. Copper activity is reinforced by the citric acid which improves photosynthesis, energy production, and resistance to stress.

  • Increases the value of nitrogen-based fertilizers
  • Increases resistance against bacterial and fungal diseases
  • Reduces the lodging risk in cereal crops
  • Corrects frequent deficiencies in black soil

In conclusion, Agro-Cu increases copper content in cells and, consequently, improves vegetative growth through greater photosynthesis activity, better nitrogen assimilation, wood hardening by its effect on the synthesis of lignin, filling corncobs, improving specific weight, resistance of the crop to diseases and abiotic stresses. Agro-Cu can be applied through the entire growth cycle, but it is important to promote early input to help sensitive crops.
