Oasis Agri Prescription Blended Trace Elements Nutrients and Functions – Part 3: Copper
COPPER (Cu)

Functions in Plants and Soil:
- Photosynthesis and Respiration:
Copper is necessary for electron transport within a plant, this is necessary for photosynthesis and respiration, helping to generate energy.
- Enzyme Activation (Coenzyme):
It is required for enzyme activation of several enzymes necessary for photosynthesis and respiration. Copper is also a cofactor for enzymes required in chlorophyll production as well as enzymes required to produce energy during flowering.
- Cell Wall Metabolism:
Copper assists in the formation of lignin, which provides structural integrity to cell walls. Again, it is necessary for various enzymatic processes.
- Stress Response:
Copper assists in protecting plants from oxidative stress.
Deficiency Symptoms in Plants:
Note: Deficiency symptoms can present differently depending on the crop species
Copper is an immobile plant nutrient. Symptoms therefore can typically occur in the youngest leaves and growing points.
- Plant Growth:
Stunted growth with shorter stems and smaller leaves.
- Leaf Symptoms:
- Youngest leaves / new leaves are deformed, twisted or curled.
- Chlorosis starting from the leaf tips and margins. Severe deficiency results in necrosis on leaf edges and between veins.
- Young leaves may wilt while older mature leaves remain dark green.
- Flowers and Fruit:
- Delayed flowering, reduced fruits and seed production.
- Flower termination before opening.
- Roots:
- Poorly developed root system.
- Discoloured brown roots. Roots may turn black after cutting.
- Crop Specific:
- Maize:
- New leaves may have a bluish-green tint.
- Leaf tips and edges may show necrosis.
- Grains:
- Young leaves may develop dry, white, twisted tips.
- Grain ears can be trapped in leaf sheath.
- Unfilled spikelets.
- Maize:
