Description
Horticultural Grade Diatomaceous Earth: Organic Soil Conditioner for Plant Growth
Horticultural grade diatomaceous earth is a natural, organic mineral derived from fossilized diatoms, rich in plant-available silicon dioxide (80%-88%) and 15+ essential trace elements (calcium, magnesium, potassium, zinc). As an OMRI-certified soil amendment, it is processed through low-temperature drying (no chemical additives) to retain its porous structure and nutrient properties—ideal for organic farming, home gardening, and bonsai cultivation.
Its unique porous structure (porosity 80%-88%, specific surface area 25-50 m²/g) improves soil aeration by 30%-50%, preventing compaction and promoting healthy root development. It retains 4-6 times its weight in water and nutrients (nitrogen, phosphorus, potassium), reducing irrigation frequency by 20%-30% and enhancing drought resistance. Additionally, its sharp microscopic edges act as a natural, non-toxic pest control—deterring soil-dwelling insects (aphids, mites, root maggots) without harming beneficial organisms (bees, earthworms).
Chemically inert, it adjusts soil pH slightly (to 6.0-7.0, neutral range) and increases soluble silicon content—strengthening plant cell walls against diseases and environmental stress (heat, cold). It is compatible with all soil types (sandy, clay, loam) and works with organic fertilizers to improve nutrient absorption rates by 15%-20%.
Hebei Hezhen Industrial Co., Ltd. produces horticultural-grade diatomaceous earth compliant with OMRI standards: moisture ≤1.2%, ignition loss ≤6%, and no synthetic additives. We offer granular (20-40mesh) and powdered (100-200mesh) forms, with products exported to Europe, America, and Australia—trusted by commercial growers, landscapers, and home gardeners for healthier plants and higher yields.
