Knowledge

Copper has the power to impact many important processes including stomatal activity, photo assimilate movement, disease resistance and insect infestation, and overall plant growth and yield.

Quick Facts About Copper

  • Copper activates enzymes and catalyzes reactions in several processes.
  • Copper is necessary to chlorophyll formation and therefore essential for photosynthesis and respiration.
  • Many vegetable crops show Copper hunger, with leaves that lose turgor and develop a bluish-green shade before becoming chlorotic and curling.
  • Similar to Manganese and Zinc, Copper is important for immobilization of free oxygen radicals.
  • Importantintheroleofpollinationofself-pollinating crops such as wheat and barley.
  • Form used by plants: Cu+ or Cu+2.

Role of Copper in Plants

  • Stimulates protein formulation.
  • Enhances Nitrogen utilization.
  • Activates several enzymes.
  • Critical in the role of photosynthesis, protein carbohydrate metabolism and respiration.
  • Has a significant influence on color development and regulates the photosynthetic electron (detoxification) of free oxygen radicals which males them harmless.
  • Important for lignification of cell walls.
  • Important for rhizome production associated with legumes.

Copper Deficiencies:

Deficiency Symptoms

  • Young leaves become wilted with chlorosis and twisting, eventually they wither and die .
  • Heads may become deformed and fill poorly.
  • Higher incidence of stem melanosis and ergot in self- pollinating crops like wheat and barley.
  • In cereals, the youngest leaves turn white due to damaged chloroplasts.

Factors Affecting Deficiencies

  • High soil pH, high organic matter, poorly drained and light sandy soils are all factors reducing Copper availability.
  • Excessive manure applications may bind Copper to the additional organic matter, further reducing availability.
  • Increasing Nitrogen impedes movement of Copper from older to newer tissue growth.
  • High concentrations of available Manganese, Iron, and Phosphorus can depress Copper absorption by plant roots and may increase the intensity of Copper deficiency.
