Sulphur deficiency made worse by
- Acidic soils
 - Light, sandy soils (leaching)
 - Low organic matter
 - Poorly aerated soils (waterlogged soils
 - ) Areas with low industrial emissions

- Chlorophyll synthesis and efficient N-utilization
 - Important in the structure of proteins, amino acids and vitamins
