Martinsville, Ohio | You probably have high Mag too? The Ca in gypsum will knock off some Mag ions, the Sulfur is needed in almost every soil and tissue test I take and gypsum is a great soil conditioner in any soil.
We use it if we can get a cheap source of it but most of it is made in to sheet rock or drywall which is in high demand in these parts.
I don't know if I would use it at $30 per ton here but if you can get closer to $10 I think you will get a good benefit from it.
The thumbrule is 35 lbs of gypsum per inch of rainfall so that figures about 1200 lbs or more per acre here while half that much would be sufficient where it rains half that much in South Dakota for example.
