Broccoli - Chlorosis
Symptoms
Symptoms of magnesium deficiency start on older leaves: Chlorosis between the veins progresses from the margins to the middle of the leaflets. The veins remain green and white respectively.
Severe deficiency leads to necrotic spots between the veins.
Causes
Magnesium deficiency
Mg uptake can be depressed by an excess of other cations like potassium, ammonium or calcium.
Both Mg and K deficiencies may appear similar, but magnesium deficiency starts as interveinal yellowing and the whole leaf shows chlorosis before necrotic spots develop. Leaf tissue analysis is recommended for confirmation.

Broccoli - Growth retardation
Symptoms
Symptoms of magnesium deficiency start on older leaves: Chlorosis between the veins progresses from the margins to the middle of the leaf blades, giving the leaf a mottled appearance. The veins remain green and white respectively.
Plant growth is stunted.
Causes

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
Broccoli: 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.
