DE FINES
Not all diatomaceous earth is the same. Here's what sets ours apart:
~90% amorphous silica — well above industry average
d50: ~16 microns, d90: ~73 microns — a consistently fine, laser-diffraction-tested distribution
<2% moisture — more usable diatomite per kg, not water weight
Kiln-dried at low, controlled temperature to preserve the amorphous silica structure
Independently tested for heavy metals, every batch
Only ACO-certified diatomaceous earth in Australia
WHAT SETS US APART
| MSD DE Fines | Other DE | |
| SiO₂ | ~90% | 70–85% |
| Particle size (d50) | ~16 microns | Varies, often much coarser |
| Moisture | <2% | Varies |
| Heavy metals | <30ppm (tested) | Unverified |
| ACO Certified | Yes | No |
APPLICATIONS
Livestock & Animal Health
Add at 2% of feed ration by weight
Supplies natural amorphous silica and trace minerals as part of the ration
Widely used in the poultry industry as a natural nutritional supplement and anti-caking agent, keeping feed free-flowing in humid conditions
Shed & Litter Management
Kiln-dried to under 2% moisture — helps manage litter and floor moisture in poultry sheds and livestock housing
Particularly useful during extended housing periods
Can be incorporated into a broader shed hygiene and biosecurity routine
ACO-certified, so it doesn't compromise organic status for certified operations
Fertiliser Efficiency & Soil Health
Improves soil structure and water retention — reducing nutrient leaching and runoff
Strengthens plant cell walls via plant-available silica — improving nutrient uptake efficiency
Even distribution carrier in fertiliser blends — reducing waste, improving application consistency
Reduces toxicity from excess nitrogen and phosphorus applications
ACO Certified — suitable for organic operators reducing reliance on synthetic inputs
Horticulture & Agriculture
Soil amendment supplying plant-available silica to depleted soils
Anti-caking carrier in fertiliser and feed blends
Seed coating for improved germination and early silica uptake
Enhances beneficial fungal activity in growing media
