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
- Adequate yields
Symptoms
Young leaves show a yellowgreen interveinal chlorosis, starting from the leaf base and spreading over the entire leaf blade (in contrast to N deficiency, where chlorosis starts on old leaves). Finally the leaf color is evenly chlorotic. Dark brown, sharply delimited spots appear mainly in the marginal area. Leaves are cupped.
Total plant height is stunted due to short internodes.
