There is no copper in "Copperas" as available from Hi-Yield. It is
ferrous sulfate. That is iron chemically bound to sulfur and oxygen
molecules as a salt of iron (like iron "rust"). It is 11% sulfur and
19% iron. It will acidify the soil as well as add iron to it to help
chlorosis.
I buy it in 15 pound bags. My soil is very alkaline--pH 8 or so. That's
why we cannot grow Japanese Iris here. But I have! Got them from
Ensata Gardens, too.
Hope this is helpful.
