Copper (Cu) activates enzymes and catalyzes reactions in several plant-growth processes. The presence of copper is closely linked to Vitamin A production, and it helps ensure successful protein synthesis.
Classified as a micronutrient, only a small amount of this essential nutrient is needed for plant survival.
Copper is the most immobile of the micronutrients.
Many vegetable crops show Cu hunger, with leaves that lose turgor and develop a bluish-green shade before becoming chlorotic and curling.
Copper is necessary to chlorophyll formation in plants and catalyzes several other plant reactions.
Influences From Other Metals
Other metals in the soil, such as iron, manganese and aluminum, affect the availability of Cu for plant growth.
Types of Soils
Organic soils are the most vulnerable to Cu deficiency; heavy, clay-type soils are least vulnerable.
Copper Deficiency Symptoms
of deficiency can vary across crop species, but similarities exist for how
nutrient insufficiency impacts plant tissue color and appearance. Nutrient
deficiencies are commonly associated with the physical location on the plant
(i.e., whether the symptoms are primarily observed on older versus newly formed
plant tissue), but these symptoms can spread as the severity of the deficiency
