While AZOMITE works through the root system, adding it to a foliar spray will get the product where it needs to be in order to be effective. Micronized and Ultrafine will suspend in liquid with agitation. With a -200 mesh and -450 mesh particle size, respectively, these powders can be added to a fertilizer solution. We recommend doing a jar test to ensure the right ratio of AZOMITE to liquid.
AZOMITE has a low salt index, so it won’t burn plants even if applied at a higher rate.
