Cauliflower - Deformation
Symptoms
Young seedlings with molybdenum deficiency show stunted growth and severe leaf deformations. Leaf blades are reduced and cupped upwards.
Leaf margins show chlorosis and slight necrosis.
Causes
Molybdenum deficiency
Symptoms of Boron deficiency look similar.
Molybdenum deficiency made worse by
- Acid soils
- Low pH
- Low levels of soil organic matter
Molybdenum is important for
- Increased yields (especially with broccoli and cauliflower), inner quality (sugar and vitamin C content) and shelf life
