Do crops need more sulfur now than we have historically thought?

Since most university nutrient recommendations were established prior to catalytic converters becoming commonplace, do you feel that sulfur fertilizer is needed in a greater amount than what is being suggested based on older recommendations?

I thought this was an interesting read: “Factors Affecting Increased Need for Calcium, Magnesium and Sulfur.” Like you suggested, the resource discusses catalytic converters as well as other factors like government restrictions on coal-burning furnaces. All of these changes add up, causing less sulfur in the atmosphere so less sulfur coming back to our soil. So, I think keeping all of this in mind when looking at older recommendations is valuable.
