Hello Rita, thanks for your inquiry and sorry for the delayed response! Cascade Minerals is similar in that it is a natural mined product from the U.S. which is used as a soil remineralizer. Our product is made from finely milled volcanic basalt, derived from Central Oregon’s Cascade Mountains. It releases essential minerals and nutrients that your plants need to flourish. Gardeners tell us that their plants are vigorous and fruits & vegetables are much better tasting when using our product.
