Attapulgite Clay & Diatomaceous Earth

Western Australia’s Locally Mined Solution for Moisture, Ammonia, and Litter Management

Australian poultry producers face persistent challenges from wet litter, which drives ammonia emissions, encourages bacterial growth, and can compromise bird welfare and productivity. While imported chemical litter amendments dominate the market, there is growing recognition of natural, locally sourced minerals — attapulgite clay and freshwater diatomaceous earth (DE) — as effective, low-risk alternatives.

Hudson Resources mines Western Australia’s premium attapulgite clay and freshwater diatomaceous earth. High surface area, porosity, and adsorption capacity make these minerals ideal for agriculture, poultry litter, filtration, and industrial applications.

These WA-mined minerals are chemically inert, non-toxic, and operate via physical adsorption and absorption. Beyond poultry, they offer broad utility across agriculture, environmental management, pet care, filtration, and industrial applications.

This report outlines the properties, applications, and advantages of raw attapulgite clay and DE, focusing on their role in poultry litter management as a key use case while highlighting their broader relevance.

1. Wet Litter Challenges in Poultry Operations

Moisture accumulation in poultry litter arises from manure, water spillage, condensation, and dense stocking. Once litter moisture exceeds 30–35%, microbial decomposition accelerates, producing ammonia, softening litter, and creating an environment conducive to disease.

Key consequences:

Footpad dermatitis (FPD): Prolonged contact with wet, ammonia-laden litter softens footpad skin, leading to lesions and bacterial infections.
Ammonia toxicity: Elevated NH₃ levels reduce growth, increase feed conversion ratios (FCR), and compromise immunity.
Operational costs: Wet litter contributes to carcass downgrades, increased ventilation needs, and higher mortality or medication costs.

Managing litter moisture is the most effective upstream intervention, and WA attapulgite clay and DE provide a natural, non-chemical option.

2. Mineral Profiles

2.1 Attapulgite Clay (Palygorskite / Fuller's Earth)

Physical Properties:

Needle-like, fibrous structure with three-dimensional channels.
High surface area, capable of binding ammonium ions (NH₄⁺) and volatile compounds.
Non-swelling and friable, preserving litter aeration.
Thermally stable and chemically inert — safe for use with livestock.

Primary Uses:

Poultry and livestock litter management.
Fertilizer carriers and soil conditioners.
Industrial absorbents, drilling muds, and chemical stabilization.
Pet care, pharmaceuticals, and aquaculture filtration.

2.2 Diatomaceous Earth (DE / Diatomite)

Physical Properties:

Composed of fossilized silica frustules from freshwater diatoms.
Extremely porous, with high moisture absorption capacity.
Mechanical desiccant effect helps maintain dry litter conditions.
Sharp silica edges provide incidental pest reduction (mites, lice).
80–90% amorphous silica ensures safety for agricultural applications.

Primary Uses:

Moisture control in poultry and livestock bedding.
Filtration in food, beverage, pharmaceutical, and water industries.
Industrial fillers and environmental remediation.
Pet care and odour control.

2.3 Synergistic Potential

When combined, attapulgite clay and DE offer complementary benefits:

Function	Attapulgite	Diatomaceous Earth	Combined Effect
Moisture management	Moderate adsorption	High absorption	Rapid, sustained moisture control
Ammonia mitigation	High CEC binding	Indirect via dryness	Minimizes volatilization
Litter structure	Friable, non-swelling	Lightweight	Aerated and easy to handle
Pest control	Limited	Mechanical	Reduces insect load
Odour control	Adsorbs VOCs	Moisture reduction	Broad-spectrum odour suppression

3. Australian Supply Advantage

Western Australia hosts 24 million tonnes of attapulgite clay and 3.5 million tonnes of freshwater DE, sourced from Hudson Resources’ mining leases. Local production offers:

Reliable domestic supply with minimal lead times.
Stable pricing in AUD, avoiding USD exchange risk.
Sustainably mined minerals with regulatory compliance.
Sovereign resource security for long-term agricultural, industrial, and environmental use.

This local availability addresses the fragility of global supply chains, which was highlighted during the COVID-19 pandemic when shipping delays and freight cost spikes disrupted agricultural input supply.

4. Applications in Poultry

Attapulgite clay and DE can be applied individually or as a blend in poultry litter to:

Maintain dry, friable bedding.
Reduce ammonia generation and VOC emissions.
Minimize footpad dermatitis and other moisture-related bird welfare issues.
Provide incidental pest control through DE’s physical action.

Indicative Application Rates:

Pre-placement: 500–1,000 g/m²
Wet-litter carry-over: 1,000–1,500 g/m²
Mid-flock maintenance: 250–500 g/m²
Wet spot targeting: 500 g/m²

Metrics to monitor: litter moisture %, ammonia levels, FPD incidence, bird weight, FCR, and mortality.

5. Beyond Poultry: Broader Industrial Relevance

WA attapulgite clay and DE serve multiple sectors:

Agriculture: fertilizer carriers, soil conditioners, livestock litter.
Industrial: absorbents, drilling muds, filtration media.
Environmental: spill clean-up, wastewater treatment.
Pet care: odour control products and absorbents.

The minerals’ versatility highlights the value of raw WA ores as high-performance, low-risk materials for diverse applications.

6. Conclusion

Western Australian attapulgite clay and diatomaceous earth are high-quality, naturally occurring minerals with unique physical properties:

Effective moisture and ammonia control in poultry litter.
Preservation of litter friability for better bird welfare.
Sovereign, locally mined supply for Australian producers.
Wide-ranging applicability in agriculture, industry, and environmental management.
