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.
