We’d like to point to a few highlights.


At AZOMITE Mineral Products, we are committed to continual research to truly understand the science behind AZOMITE. While AZOMITE was created 30 million years ago when a volcano erupted into a seabed, and the deposit was discovered in the 1940s, we are always looking to perfect its uses and optimum application methods. We also like to show you that it works. So take a look at our Research section, where we have tested AZOMITE on a variety of crops in a variety of locations.

Our Product Line

AZOMITE is a natural deposit, which we blast and mine, and crush, granulate, and pelletize it for different application methods. We have Pelletized, Granulated, Field Grade, Micronized, and Ultrafine—all AZOMITE. You can read about the different uses and advantages for each of our grades on the Products page. And of course, if you have any questions or would like a sample, please contact us using the contact form below.


Ultrafine is our finest grade, where 90% of particles will pass through a 450-mesh screen. The fine powder is ideal for field crop drip or other irrigation systems, as a spray tank additive for foliar feeding, use in greenhouses, hydroponic systems or applying when planting or  blending with potting soil.

Micronized is a powder with flour-like consistency, where 90% of particles will pass through a 200-mesh screen. Micronized is ideal for blending in soil or applying directly when planting.

Field Grade

Field Grade mimics a coarse sand. Particle sizes range from 1/8” to powder for both rapid and longer-term results. Field Grade is designed for composting and blending with other products in application.

Granulated is agglomerated into easy-to-handle granules with only a modest amount of dust. Applied to the soil, granules will break down over a week or two once irrigation hits.

Formed as an extruded pellet, Pelletized is easy to handle and apply. These pellets will break down to powder immediately when moisture hits it, so it will start working right away.
