Down To Earth AZOMITE, the “A to Z Of Minerals Including Trace Elements,” is a natural trace mineral product formed from the dust of an ancient volcano in central Utah. AZOMITE can improve plant and root system growth, crop yields, quality and flavors as well as re-mineralize nutrient depleted soils. This powder grade is ideal for blending with other fertilizer materials or amendments as a trace mineral resource to help meet plant nutritional needs. It can be applied directly or in combination with composts, fertilizers, manures or soil inoculants.
