I have been given some Hi-Yield brand "Copperas". Is it a good or bad product? It says it is for increasing the iron in the soil. I have not been able to find out if it is truly "organic". thanks

Copperas and other iron products that are rust color are highly likely to be comtaminated with heavy metals because they are basically industrial waste. Pure iron sulfate is either blue or white.

The product is 11% sulfur and 19% iron, ferrous sulfate. Because this is a very common product line at Ace Hardware, I would think someone would actually know the answer? I don't want to guess! thanks

I would then presume it was
11% sulfur
19% iron
70% 'unknown c*** you likely wouldn't want so we won't list it'
