I believe that stuff is calcium sulfate, otherwise known as gypsum.
It comes in little pellets. We use it here on the west coast to
decrease the pH of the soil (it is alkaline here). The sulfate
ions I guess are what does it. It breaks down slowly I guess. I'm
not sure what effect the calcium has. We also use peat moss to
acidify the soil. It has a more immediate effect.
