I don't know how it is in the States but here in the UK sulphur emissions have dropped 97% (2017) from 1970. This is due to a decline in coal use in power stations. Therefore, adding fertiliser in the form of sulphates here I think is pretty useful.
While on mesonutrients, Calcium and Magnesium are problems in my area of the UK where it's very rainy, there is granitic bedrock and the mains water has very low mineral content. Fertilisers have to be marketed to the broadest customer base, so given many are on alkaline or chalky soils magnesium and calcium aren't included in standard compound fertilisers. The fertiliser industry has caught up with reduced S deposits in soils and there are complex fertilisers with S (and TEs).
There are a lot of products that seem to promote potassium as a means for improved flowering. If a plant is deficient in potassium growth will be stunted and all means of its lifecycle will be affected including flowering. It is misleading to say potassium will give you more flowers than normal, when applying it you are improving overall growth and development. In Illinois soils, potassium deficiency is uncommon and often these products are overapplied.

23:00 Why is it that Potassium sulfate is sold to promote flowering and fruiting?

45:50 - An easy explanation on how lime works to increase the pH level.
Good lecturer, but the slides stopped working from 46mins on
Very interesting lecture!
Unfortunately the slides stoppes mid in, wich makes it harder to follow when english is second language.
helped me study for my midterm
That was prrrrrrrretttttttttty interesting
Soil Science without downloadable slides doesn't turn bad soil good... :) Nice lecture though.
