Organic Azomite 0-0-0.2 Micronized is an OMRI Listed natural mineral soil amendment mined from a single hydrated sodium calcium aluminosilicate (HSCAS) deposit in central Utah — volcanic ash that settled into a mineral-rich seabed roughly 30 million years ago. One product supplies approximately 70 trace and ultra-trace elements, including silica, calcium, magnesium, iron, manganese, zinc, boron, and rare earth elements.
Trace minerals act as cofactors for the enzymatic reactions behind plant metabolism — the work that standard N-P-K fertilizers do not address. Azomite is a long-cycle remineralizer best suited to soils depleted by years of intensive cropping and irrigation, with cumulative benefits typically seen over two to three growing seasons of regular use. It works across vegetable gardens, fruit trees, lawns, and greenhouse potting mixes, and is micronized to roughly −200 mesh for even broadcast distribution and good soil contact.
Azomite is a soil-building amendment, not a primary fertilizer — it supplies almost no nitrogen, phosphorus, or potassium, so it should be paired with a complete fertilizer program. It is largely insoluble and is not intended as a hydroponic reservoir nutrient. It is also approved as a livestock and poultry feed supplement, a separate use that should follow species-specific feed guidance. Work it into the soil, water in, minimize dust when handling, and store sealed and dry.
OMRI Listed and independently lab tested, with heavy metal results consistently well below required limits.
