Cereals - Growth retardation
Symptoms
The number of grains sites and the size of grain is reduced under S deficiency.
S deficient plants show a bright chlorotic, yellow green colour and stunted growth. Chlorosis caused by sulphur deficiency is observed at the young leaves first.
Reasons
Sulphur deficiency
N deficiency and root damage may cause similar symptoms.
Cereals - Growth retardation
Symptoms
S deficient plants show a bright chlorotic, yellow green colour and stunted growth. Chlorosis caused by sulfur deficiency can often be observed at the young leaves first - in contrast to deficiency symptoms caused by a lack of nitrogen.
The number of grains sites and the size of grain is reduced under S deficiency.
Reasons
Sulphur deficiency (right)
N deficiency and root damage may cause similar symptoms. Symptoms of N and S deficiency in wheat and other small grains are very similar, thus a tissue analysis is often necessary to reveal the cause.
Cereals - Growth retardation
Symptoms
Ears are small.
Reasons
Sulphur deficiency (left)
Cereals - Growth retardation
Symptoms
Leaves of S deficient plants exhibit a bright yellow-green chlorotic colour. Chlorosis normally starts on the young leaves.
The whole plant including the ears shows stunted growth and yields poorly.
Reasons
Sulphur deficiency
Symptoms of N and S deficiency in cereals are very similar, thus a tissue analysis is often necessary to reveal the cause.

Sulphur deficiency made worse by
- Acidic soils
- Light, sandy soils (leaching)
- Low organic matter
- Poorly aerated soils (waterlogged soils
- ) Areas with low industrial emissions
Sulphur is important for
- Healthy green foliage
- Even crop maturity
- More efficient use of nitrogen by the crop
- Improved grain protein contents
Yara recommended fertilizers for Sulphur
YaraVita THIOTRAC 300
Cereals: 5 l/ha at pseudo stem erection to first node detectable (Zadok's G.S. 30-31). For moderate to severe deficiency, repeat applications at 10-14 day intervals. Water rate: 200 l/ha. Wheat Only: In addition: 3 to 5 l/ha at half inflorescence (ear) emerged to end of milk development stage in grain ripening (Zadok's G.S. 55-79) or two applications of 5 l/ha in the period flag leaf ligule just visible to the end of the milk development stage in grain ripening (Zadok's G.S. 39 to 79). Water rate: 200 l/ha.
