Top Dressing

Using AZOMITE® in starter fertilizer is a great way to get the product close the plants—and the roots—where it can have the most benefit. Any of the three grades will work for top dressing: Micronized, Field Grade, or Granulated. When deciding which grade will work for you, keep in mind size, amount of dust, and any mechanisms that AZOMITE® will need to pass through. We are happy to help you determine what grade is right for your situation.

Because AZOMITE® is a naturally occurring material, there isn’t a problem with it leaching out of the soil. While we recommend applying AZOMITE® once or twice per growing season, irrigation isn’t going to wash it away.
