Cabbage - Growth retardation
Symptoms
Stunted growth caused by Cu deficiency.
Causes
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
- Chalky 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
Yara recommended fertilisers for Copper deficiency
YaraVita COPTREL 500
Cabbage: 0.5 l/ha applied at the 4 to 6 leaf stage. For moderate to severe deficiency, one or two repeat applications should be made at 10 to 14 day intervals. Water rate: 200 l/ha.
