Or buy from your local turf supplier. It may not be as 'refined' of a grade but you don't need it to be for turf. Some of these products are meant for hydroponics and other very sensitive applications & they don't require as much product, so that 5# goes a long way.john5246 said:can you put a link to that? I can't seem to find it. Based on the 5lb bag price I would imagine the 25lb bag is 1000 bucks?TheZMan said:I got a bag off Amazon from the link in the beginning. It's greenway biotech.

Heres SiteOne's Ferrous Sulfate, $30/50#bag (with an account).
