Copper deficiency vs. healthy plant-Cabbage

Reasons
Copper deficiency (right) Copper deficiencies are more common on organic or sandy soils and where excessive nitrogen rates have been applied.

Cabbage - Deformation

Symptoms
Leaves are rather elongated in shape and bent down. Their color is pale with broad white leaf veins. Plant habitus is loose, headforming inhibited.

Copper deficiency vs. healthy plant made worse by

Organic soils
Calcareous soils
Sandy soils
Reclaimed heathland
High nitrogen applications

Copper is important for

Lignin formation, chlorophyll performance and regulation of superoxide radicals
Necessary for blue pigment plastocyanin, seen in broccoli florets
