Role of Sulfur in Potato Production
Sulfur effect on common and powdery scab
Sulfur helps to reduce the level of common and powdery scab. This effect may be due to a reduction in the soil pH where elemental sulfur is used.
Sulfur and common scab
Best effects come from applying sulfur to the soil in a readily available form at planting. However, a program of foliar sulfur can also reduce scab, as study in Scotland shows.
General guidelines for sulfur application
The potato crop has a demand for sulfur in similar quantities to magnesium. Where potassium sulfate is commonly used, supplies are usually adequate. Best effects come from applying sulfur to the soil in a readily available form at planting.
