Now you are applying 24-36# of S with the AMS. 500# of gypsum would be 90# of S. S doesn't hold over well from year to year so the extra 55-65# of S seems like a waste. I vote for keeping using the AMS ahead of corn and blend elemental sulfur with potash in the fall ahead of beans.
Anyone use 500ish# of Gypsum as their Sulfate source?
