Cabbage - Deformation
Symptoms
Symptoms of magnesium deficiency start on older leaves.
Chlorosis between the veins progresses from the margin to the middle of the leaf. First the affected areas turn yellow-green, later color changes to orange or red. The small veins also become chlorotic, but the bigger ones remain green and white respectively.
The interveinal zones curl up.
Growth reduction is only slight when deficiency is moderate, but increases with severe deficiency.

Cabbage - Deformation
Symptoms
Affected plants are not reduced in leaf size. Head forming is inhibited, plants show a loose habitus with rather elongated leaf shape.
Older leaves turn yellowgreen.

Causes
Magnesium deficiency
Magnesium deficiency made worse by
- Sandy soils
- Acidic soils
- Potassium rich soils
- Soils receiving high potash applications
- Cold wet periods
Magnesium is important for
- Increases photosynthetic activity maintaining good growth for high yields
- Improves storage quality
Yara recommended fertilisers for Magnesium deficiency
YaraVita MAGFLO 300
Cabbage: 2-4 l/ha at 4 to 6 leaf stage, with repeat applications at the above rate at 10 to 14 day intervals for moderate to severe deficiency. Water rate: 200 l/ha.
