Sulfur deficiency

Constraint – Sulphur 

Plant use

  • Sulphur is a macronutrient
  • Sulphur is involved in the formation of several amino acids, proteins, and vitamins and for chlorophyll production
  • It also helps the plant to resist stress from weather, insects and diseases

Symptoms 

  • Plants appear stunted and spindly
  • Small, pale, yellow-green leaves with lighter coloured veins
  • Young leaves are affected first

Damage

Yield penalty can occur if left untreated

Management

A soil test or a plant tissue test should be used to confirm sulphur deficiency. Application of a suitable amount of sulphur based fertiliser is normally sufficient to correct deficiencies.
