Testing soil is a good idea and I even have my own pH meter and some other stuff.

The soil remineraliztion amendments I mentioned don't affect pH. They operate on the theory that soils are generally depleted of trace minerals and need to be supplemented every so often. I was thinking I might set up a few 5 gallon buckets of tomatoes for a more controlled comparison. This would be in addition to my garden plots.

Maybe it's bunk, maybe its legit. I am getting a pretty good tax refund soon so I can spring for the cost. smile
