We had some gypsum given to us. They tried to spread it to heavy and to fast. It ended up being a heavy application about 10 ft wide and then tapered off to the 40 spread it was supposed to be. 5 years later soil tests still showed more sulfur in the middle of the pattern.
To me that means it does, at least to some extent. If you looked you could still see the middles 3 years later. Oddly enough the high and low rows yield the same. | |

Anyone use 500ish# of Gypsum as their Sulfate source?
