What is DE FINES?

DE Fines is a high-performance diatomaceous earth sourced from a rare freshwater volcanic lake deposit in Junction View, Queensland.

At 90–92% amorphous silica, it significantly exceeds the industry average of 85% — delivering higher performance across every application.

It is the only diatomaceous earth in Australia certified as an organic input by Australian Certified Organic (ACO) — making it the natural choice for certified organic farming, livestock supplementation, and premium agricultural inputs.

 

How DE Fines is used

Livestock & Animal Health A natural feed supplement with a long history of use across cattle, sheep, goats, alpacas, poultry, cats and dogs. Suitable for certified organic and chemical-free farming operations.

  • Add at 2% of feed ration by weight

  • Provides bioavailable silica and trace minerals in a readily absorbable form

  • Widely used in the poultry industry as a natural nutritional supplement

Natural Pest & Insect Control Works as a physical insecticide — microscopic silica particles damage insect exoskeletons causing desiccation. No chemical residue, no risk of resistance developing, safe around animals and humans.

  • Stored grain pest and weevil control

  • Poultry sheds and animal housing

  • Fungus gnat and soil insect control in propagation and nursery environments

Fertiliser Efficiency & Soil Health As input costs fluctuate, DE Fines helps farmers extract more value from every dollar spent on fertiliser.

  • Improves soil structure and water retention — reducing nutrient leaching and runoff

  • Strengthens plant cell walls via bioavailable silica — improving uptake efficiency of applied nutrients

  • Even distribution carrier in fertiliser blends — reducing waste and improving application consistency

  • Reduces toxicity from excess nitrogen and phosphorus applications

  • ACO Certified — suitable for organic operators looking to reduce reliance on synthetic inputs

DE Fines does not replace nitrogen, phosphorus or potassium fertilisers — it helps your existing inputs work harder and go further.

Horticulture & Agriculture Approved for use in organic farming programs.

  • 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
