Symptoms
Chlorosis starts in young leaves and proceeds to the older leaves with ongoing deficiency. Leaves often show red discoloration. They are stiff and curled inwards.
With severe deficiency seedlings die off.
Reasons
Severe sulphur deficiency on seedlings
Cauliflower - Chlorosis
Symptoms
Chlorosis starts in young leaves and proceeds to the older leaves with ongoing deficiency. Leaves turn uniformly light green or yellow. They are stiff. Often only thin petioles are formed
Later on affected leaves weather and curl inwards.
Reasons
Sulphur deficiency
Sulphur deficiency is similar in appearance to nitrogen deficiency, however it begins on younger leaves because sulfur is not as mobile as nitrogen within the plant.

Sulphur deficiency is similar in appearance to nitrogen deficiency, however it begins on younger leaves because sulfur is not as mobile as nitrogen within the plant.
Sulphur deficiency made worse by
Acidic soils
Light, sandy soils (leaching)
Low organic matter
Poorly aerated soils (waterlogged soils
) Areas with low industrial emissions
Sulfur is important for
Requirement of steady supply in relatively high quantities
Important for head development and stress tolerance
Major role in crop quality
Better inner quality determinants and improved storage quality
