Role of Sulfur in Potato Production

Sulfur plays a role in nitrogen stabilization and amino acid and protein 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.
