Azomite Micronized (44 lb)

Good Source of Trace Minerals and Calcium

Azomite Micronized (44 lb) is a premium-grade, ultra-fine azomite fertilizer designed for large-scale soil enhancement and improved plant growth. Azomite is a natural mineral product sourced from ancient volcanic deposits, providing a broad spectrum of minerals and trace elements—over 70 in total—including essential nutrients like calcium (1.8%), magnesium (0.5%), and potassium (0.2%). This azomite micronized powder supports root strength, improves soil structure, and boosts crop yields. As a trusted ingredient in many organic products, it is an excellent choice for farmers, landscapers, and commercial growers seeking sustainable and natural solutions for healthier plants and soils.

Key Benefits:

  • Comprehensive Soil Amendment: Supplies essential minerals for optimal plant development and soil health.
  • Enhances Nutrient Uptake: Helps plants absorb key nutrients for stronger growth and higher yields.
  • Improves Soil Structure: Increases aeration, water retention, and microbial activity.
  • Ideal for Large-Scale Use: Suitable for farms, orchards, vineyards, and commercial agricultural applications.
  • Supports Sustainable Agriculture: OMRI-listed for organic use and free from synthetic additives.

Application Guidelines:

  • Soil Preparation: Apply 3-5 lbs per acre before planting to enrich the soil with essential trace minerals.
  • Foliar Application: Can be applied as a foliar spray with proper tank agitation. Use at a rate of 3-5 lbs per acre.
  • Irrigation System Compatibility: Works effectively in irrigation systems when used with adequate agitation, such as a gypsum machine, and proper screen and nozzle sizes.
  • Field Crops & Pasture: Broadcast 50-100 lbs per acre annually for long-term soil enrichment.

How Azomite Works:

Azomite enhances plant resilience by improving root structure, increasing water retention, and supplying trace minerals often missing in depleted soils. It has been widely used for over 50 years as a trusted natural soil amendment for organic farming and sustainable agriculture.

    AMAZING PRODUCT!

    Azomite is amazing! Used it on a 25 year old peach tree that was badly neglected. This tree produces beautiful peached BUT it had NO TASTE! Like eating paper! Was introduced to Azomite & the next year, the peaches were off the hook!!!! NEVER expected a change like this & it was so inexpensive to use! One of the best kept secrets, in my opinion!!!! HIGHLY recommend this product!

    Secret Ingredient

    I’ve been using Azomite in my gardens for 15 years and I wouldn’t plant or amend without it. A real staple in my fertilizer pantry. Because the source mined in Nevada is finite, IMO, I recommend not wasting bags of it it on poultry feed. It’s best use is a long term application back into the ground. It takes a couple years for a home gardener to use one bag in a veggie or herbaceous perennial patch or establishing new fruit trees. This stuff is truly very special and will make your hard work that more rewarding.

    Plants love This Product

    This is such a great amendment to add to depleted soil. It is very powdery, so if applying might want to wear a dust mask. But it is micronized so you can mix it in water and water it in. Just keep stirring cause it settles out.
