I proved to myself that it works as stated the first time I used it. I had seedlings that I had not yet transplanted because they were far behind the ones I had already transplanted. I added azomite to their potting soil and they caught up with the others in one week. By the end of the second week they were ahead of the others.
I live on a sand dune. The sand easily leaches all trace miinerals out as the water easily drains through it. No matter what variety of tomatoes I planted, they all tasted the same. After using azomite each tomato variety had its own flavor.
My beets are so sweet that I have to reduce the amount of sugar in the pickling brine.
