| Look here http://www.diamondkgypsum.com/agri.html If 95% is available in California for $70/ton, you should be able to get it to Minn for a little more. This is very high quality spreadable mined gypsum, not the solution grade. Diamond K spreadable gypsum is overpriced for California, we do not see much of it here. I would get a Lab analysis on powerplant gypsum before I put it on my farm. | |
