| I don't see any gypsum in the list. Calcium carbonate is slaked lime. Gypsum has about 23% calcium and 19% sulfur. I would not put it on our ground even if someone else spread it for free. We will no longer spread any sewer sludge in any form in our custom spreading business. When you said that the sludge has been heated, does that mean composted? I believe poorly composted sewer sludge caused me respiratory problems when we used to spread it. It's free because that is what it is worth. | |

IS this a good gymsum/fertilizer product?
