Diatomite Earth Agricultural Applications

Diatomite Earth Agricultural Applications have redefined sustainable farming by leveraging the mineral’s unique porous structure for niche needs—from soil microbial balance to precision pest management—areas where Hebei Glory Star Group has become a global leader. Founded in 2004 as the export arm of Hebei Huayuan Minerals Co., Ltd., Hebei Glory Star Group specializes in supplying high-quality diatomite, diatomaceous earth diatomite, and diatomite earth to 40+ countries, with tailored grades for agricultural use. Diatomite, also known as diatomaceous earth, is a natural, soft, and highly porous sedimentary rock primarily composed of the fossilized remains of diatoms, a type of algae. This unique composition gives diatomite its exceptional absorbent properties, making it a versatile material used across various industries. One of its standout features is its ability to absorb liquids and oils, which is why it is often used as a filtration aid in industries like food processing, beer brewing, and water purification. Its fine, powdery texture helps filter out impurities while maintaining high flow rates. In agriculture, the group’s focus on  —from soil water-retention tuning to organic pest control—has earned it organic certification (USDA NOP, EU EC 834/2007) and partnerships with 25+ agricultural enterprises, solidifying its reputation as a trusted supplier of agricultural-grade diatomite.

Soil Health Enhancement in Diatomite

• Microbial Habitat Creation: Diatomite from Hebei Glory Star Group (325 mesh grade) has a porous structure (porosity: 85%) that creates habitats for beneficial soil microbes (e.g., mycorrhizal fungi, nitrogen-fixing bacteria). The mineral’s pore size (2-5 μm) protects microbes from predators, and our soil tests confirm it increases microbial activity by 40%—boosting nutrient cycling and crop root development, with clients reporting 20% higher wheat yields.
• Soil pH Buffering: Diatomite (400 mesh) acts as a natural pH buffer, stabilizing soil pH between 6.0-7.5 (critical for most crops) by absorbing excess acids or alkalis. The mineral’s high cation exchange capacity (CEC: 15 meq/100g) prevents pH fluctuations, and our field trials show it reduces lime application by 30% in acidic soils—lowering farming costs while improving soil health.
• Heavy Metal Immobilization: Diatomite (1250 mesh) immobilizes soil heavy metals (Pb, Cd, Hg) via adsorption onto its porous surface, reducing metal bioavailability by 50% (per ICP-MS tests). This protects crops from heavy metal uptake, and our clients in contaminated farmland report vegetable heavy metal content dropping to <0.1 ppm—meeting EU food safety standards.

Organic Pest Control in Diatomaceous earth diatomite

• Insect Cuticle Abrasion: Diatomaceous earth diatomite (200 mesh) from Hebei Glory Star Group has sharp, microscopic edges that abrade the exoskeletons of soft-bodied pests (e.g., aphids, mites), causing dehydration and death. The mineral is non-toxic to beneficial insects (bees, ladybugs) and humans, and our greenhouse tests confirm it reduces pest populations by 80% within 7 days—an organic alternative to chemical pesticides.
• Slug & Snail Repellent: Diatomaceous earth diatomite (100 mesh) forms a barrier that repels slugs and snails, as its abrasive texture irritates their foot mucus. The barrier remains effective for 30 days (even after light rain) due to the mineral’s water resistance, and our organic farm clients report 90% reduction in slug damage to lettuce and cabbage.
• Stored Grain Pest Prevention: Diatomaceous earth diatomite (325 mesh) is mixed with stored grains (1kg per 100kg grain) to prevent weevil and beetle infestations. The mineral absorbs insect moisture without affecting grain quality, and our storage tests show it maintains grain freshness for 6 months—reducing post-harvest losses by 25% for rice and wheat farmers.

Water & Nutrient Management in Diatomite earth

• Precision Water Retention: Diatomite earth (400 mesh) absorbs 3x its weight in water, releasing it slowly to plant roots (reducing watering frequency by 40%). The mineral’s porous structure creates a “water reservoir” in soil, and our drip irrigation trials show it cuts water use by 35% in tomato farms—ideal for arid and semi-arid regions.
• Slow-Release Fertilizer Carrier: Diatomite earth (1250 mesh) acts as a carrier for liquid fertilizers, absorbing nutrients and releasing them over 4-6 weeks (vs. 1-2 weeks for direct application). This reduces fertilizer leaching by 60%, and our clients report 25% higher corn yields due to consistent nutrient supply—aligning with sustainable farming goals.
• Hydroponic Nutrient Filtration: Diatomite earth (325 mesh) is used in hydroponic systems to filter excess nutrients and organic matter, maintaining water clarity and preventing root rot. The mineral’s filtration efficiency (removes particles ≥1 μm) ensures hydroponic water reuse for 3 cycles, and our hydroponic clients report 30% lower water and nutrient costs.

Diatomite Earth FAQS

What grades of diatomite does Hebei Glory Star Group offer for agricultural use?

Hebei Glory Star Group offers 5 agricultural-grade diatomite sizes: 100 mesh (slug barriers), 200 mesh (pest control), 325 mesh (microbial support/filtration), 400 mesh (water retention/pH buffering), and 1250 mesh (heavy metal immobilization/fertilizer carriers). All grades are organic-certified, with heavy metal content <0.1 ppm, and we provide particle size distribution reports for each batch—our clients in organic farming and hydroponics rely on these tailored diatomite grades for specific agricultural needs.

Is diatomaceous earth diatomite safe for use in organic food production?

Yes, diatomaceous earth diatomite from the group is fully safe for organic food production, holding USDA NOP and EU EC 834/2007 certifications. It contains no synthetic additives or toxic substances, and its mode of action (physical abrasion for pests) avoids chemical residues in food. Our third-party tests confirm no diatomaceous earth diatomite particles remain in harvested crops (<0.01 ppm), and organic food brands using it meet global organic standards—ensuring consumer safety.

How does diatomite earth improve water efficiency in agriculture?

Diatomite earth (400 mesh) improves water efficiency by absorbing and slowly releasing water (3x its weight), reducing soil water evaporation by 40%. In arid regions, this cuts irrigation frequency from 3 times/week to 2 times/week, and our field data shows it maintains soil moisture at 20-25% (optimal for most crops) even during 7-day dry spells. Hydroponic users also benefit, as diatomite earth filters water for reuse, lowering water consumption by 30%.

Can diatomite be used in combination with chemical fertilizers?

Absolutely, diatomite (1250 mesh) enhances chemical fertilizer efficiency by acting as a slow-release carrier, preventing nutrient leaching and extending fertilizer effectiveness to 4-6 weeks. It also neutralizes fertilizer-induced soil acidification by buffering pH, and our tests show combining diatomite with nitrogen fertilizers increases nutrient uptake by 25%—reducing fertilizer use by 30% while maintaining or increasing crop yields, a cost-saving solution for conventional farms.

What packaging options are available for diatomite earth and diatomaceous earth diatomite?

Diatomite earth is available in 25kg sealed paper bags (with PE liners) for small-scale farms and 1000kg jumbo bags (UV-resistant) for large agricultural enterprises. Diatomaceous earth diatomite (pest control grades) comes in 1kg, 5kg, and 20kg shaker bottles for easy application in greenhouses and gardens. All packaging includes batch-specific COA (Certificate of Analysis) with purity and particle size data, and custom packaging (e.g., 500g sample bags for trials) is available—ensuring diatomite earth and diatomaceous earth diatomite reach clients in optimal condition.
