Symptoms
Distorted leaves with reduced leaf area and chlorotic leaf margins. "Whiptail" formation.
Symptoms begin at the younger leaves
Reasons
Molybdenum deficiency
Cauliflower - Deformation
Symptoms
Socalled "whiptail" formation: Leaf area is reduced partly till to the midrib.
Symptoms begin at the younger leaves
Reasons
Molybdenum deficiency.
Cauliflower - Deformation
Symptoms
If molybdenum deficiency occurs in a late stadium of development, loose curds are formed. In addition small leaves and bracts penetrate the curd surface.
Reasons
Molybdenum deficiency of curd
Cauliflower - Deformation
Symptoms
If molybdenum deficiency occurs in a late stadium of development loose curds are formed. In addition small leaves and bracts penetrate curd surface.
Reasons
Molybdenum deficiency of a curd (right) compared to optimum supply (left).
Cauliflower - Deformation
Symptoms
Young seedlings with Boron deficiency show stunted growth and severe leaf deformations. Leaf blades are reduced and cupped upwards.
Leaf margins show chlorosis and slight necrosis.
Reasons
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
