Symptoms
Uniform chlorosis allover the foliage. Mature leaves start wilting and show marginal chlorosis with subsequent necrosis spreading over the leaf blade. Finally older shoots become completely scorched. Growth and yield are severely decreased.
Reasons
Sulphur deficiency
Plant tissue content is 0.1-0.2% dry weight normally. Even though subtle differences between N and S deficiency symptoms exist (N deficiency occuring first on older, S deficiency symptoms on younger leaves), an exact diagnosis is difficult. Plant analysis is recommended.

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
Component of enzymes and other proteins
Necessary for chlorophyll formation and efficient N-utilization
