AZOMITE is a great additive to compost teas because of the addition of volcanic ash properties. The ideal grade of AZOMITE for this method is Field Grade, though any of the grades will work. Field Grade has moderate dust, but it’s easy to handle, and is available in bags, totes and bulk. We recommend using 25-50 pounds per ton of compost.
Field Grade is similar to coarse sand. It’s the basic grind of AZOMITE after we bring it out of the mine.
