ABOUT AZOMITE ROCK DUSTAzomite rock dust is a naturally mined volcanic rock composed of over 70 minerals and trace elements that are essential for optimal plant health. The rock formation in Utah from which Azomite is mined was formed when volcanic ash merged with sea water an estimated 30 million years ago. This mixture of volcanic ash and sea water created a unique source of trace minerals and elements that moist soils are void of. Just like humans, plants require many minerals to reach peak health and vigor. Scientists have long recognized that adequately nourished plants and animals are resistant to infectious diseases. There is a growing recognition that healthy plants may effectively resist insects. There is speculation that the nutrient-dense sap of healthy plants provides protection against freeze damage. Based on research studies, reporting higher trace element levels, we believe your plants will show trace element and nutrient improvement with AZOMITE® use.Benefits of Glacial Rock Dust· Improve root systems· Increase plant vigor· Increase yields· Excellent source of macro and micro nutrients· Increases germination rate· Enhanced pest and disease resistance How to use Azomite Rock DustTransplanting and pre-mixing soil for potted plants: 8 tablespoons into 1 gallon of soil or growing medium.Top dressing potted plants: 4 tablespoons per 1 gallon of soil or growing medium.
