Sulfur deficiency made worse by

  • Acidic soils
  • Light, sandy soils (leaching)
  • Low organic matter
  • Poorly aerated soils (waterlogged soils
  • ) Areas with low industrial emissions

Sulfur is important for

  • Green foliage and healthy growth
  • More effective use of nitrogen by the crop
