I needed five tablespoons of gypsum (calcium sulfate) for a mushroom spawn project so I went to the feed store. I couldn't find a small bag or box on the shelves, so I asked the clerk. She said that all they had was a 50-pound bag for $9.99. I figured that for only ten dollars, I'd buy the sack and use the excess somewhere.

There doesn't seem to be a lot of use for gypsum, other than breaking up clay soil for better drainage, which isn't a problem for us. I guess I could just spread it around the pasture, figuring that the calcium will eventually get into the grass, which will give my sheep stronger bones when they eat it.

Any novel ideas of what to do with 49.99 pounds of pelletized gypsum?
