Copper (Cu) is a trace element that plants need in small but essential amounts. It plays a role in chlorophyll synthesis, photosynthesis, and protein-vitamin formation. Its deficiency reduces yield and quality, especially in fruit trees and cereals. This guide covers the symptoms and causes of copper deficiency and its foliar treatment with DoraCop.
Copper's Role in Plant Growth
Because copper is involved in chlorophyll production, it directly affects photosynthetic efficiency. It is also a component of many enzymes and contributes to protein and vitamin formation. Insufficient copper weakens the plant's energy production and tissue resilience.
Symptoms of Copper Deficiency
Copper deficiency usually starts in young leaves and shoot tips:
- Wilting, curling, and tip burn on young leaves.
- Dieback at shoot tips.
- Poor ear development and reduced grain fill in cereals.
- Weak shoot growth and low yield in fruit trees.
Because these symptoms can be confused with other deficiencies, a definitive diagnosis should be made with soil and leaf analysis. To learn how to take a sample, see our soil analysis guide.
Causes of Copper Deficiency
- High-pH (calcareous) soils: reduce copper availability.
- High organic matter: can bind copper and block it from reaching the roots.
- Excess phosphorus or zinc: creates antagonism with copper uptake.
- Sandy, leached soils: have low natural copper content.
The DoraCop Solution
DoraCop is a liquid fertilizer containing 6% water-soluble copper, recommended for advanced copper deficiency. Foliar-applied copper is highly effective within the plant and delivers fast results. DoraCop should be applied on its own and not tank-mixed with other products. It is especially effective on fruit trees and cereals and is suitable for organic farming. For dosing, we recommend consulting our technical team.
Tips to Prevent Deficiency
- Carry out regular soil and leaf analysis.
- Balance pH to the crop's needs.
- Avoid excessive phosphorus and zinc application.
- Apply a preventive foliar copper program during high-risk periods.
Trace elements are needed in small amounts, yet their deficiency can be the first factor limiting yield even when macronutrients are sufficient.
