Mercer County, Ohio on the Indiana line | I picked up a few loads of gypsum from a guy that I'm getting nervous about. I haven't tested it for heavy metals at all and I don't want to hurt my ground. At this point I have enough at one farm to put .8 tons of gypsum on per acre.
What kind of test should I run and what levels can a farm take without adding it year after year? I have accounts with Midwest and Brookside Labs. |
Heavy metals in gypsum?
