Copper (Cu) is a micronutrient which is only needed in trace amounts, but is involved in several key plant actions, including photosynthesis, nitrogen utilization, protein production and water regulation. Copper deficiency is becoming more widespread across Western Canada, limiting a crop’s growth and reducing yield potential. In this post we will examine the role of copper in the plant, consequences of copper deficiency and solutions to provide cu to your crop.

Identifying and addressing a copper deficiency can make a big difference when it comes time to harvest. 

Copper (Cu) is a micronutrient which is only needed in trace amounts, but is involved in several key plant actions, including photosynthesis, nitrogen utilization, protein production and water regulation. Adequate copper is needed for lignin formation, affecting the overall strength of the plant, and is critical for proper seed formation.

Well-balanced nutrition plays a key role in crop growth and development. There are many micronutrients essential for plant growth including boron, calcium, copper, manganese and zinc. However, deficiencies, biotic and abiotic factors can inhibit a crop’s ability to take in the nutrients it needs.

For example, high pH soils, high organic matter soils or light textured and sandy soils are all prone to zinc deficiency. Crops growing in zinc deficient soils may exhibit stunted growth and small or misshapen leaves. To help supplement zinc deficiency and promote robust crops, I recommend OMEX’s Zintake, a foliar fertilizer with high concentrations of phosphorus, potassium and zinc.
