Freshwater diatomaceous earth (amorphous silica mineral)
DE-CIDE® is a naturally occurring freshwater diatomaceous earth sourced from Western Australia, supplied as a fine amorphous silica mineral powder for agricultural and environmental applications.
It is derived from fossilised microscopic aquatic organisms known as diatoms and processed into a stable, high-purity mineral input.
Agricultural diatomaceous earth mineral input
DE-CIDE® is used where diatomaceous earth is required as a physical mineral input in agricultural and land-based systems.
It is commonly selected for applications involving:
- moisture management in dry agricultural environments
- physical mineral interaction in soil systems
- silica-based mineral supplementation programs
- storage, handling, and farm infrastructure systems
Applications of diatomaceous earth (DE-CIDE®)
DE-CIDE® diatomaceous earth is used across a wide range of agricultural, farming, and environmental systems where a stable, natural mineral input is required.
It is commonly applied in environments including:
- grain storage and post-harvest handling systems
- agricultural and horticultural production environments
- composting and organic material processing systems
- poultry housing and dry litter management systems
- farm infrastructure, sheds, and laneway environments
- broadacre and commercial agricultural operations
- general farm hygiene and dry material management systems
DE-CIDE® is selected where a high surface area, amorphous silica mineral is required for physical, non-chemical environmental applications.
Physical moisture management & desiccation properties
DE-CIDE® functions through its physical structure, high surface area and natural porosity properties rather than chemical activity.
These properties enable:
- strong moisture adsorption
- physical desiccation behaviour in dry environments
- interaction with soil particles and organic matter
- stable performance as a non-reactive mineral input
Why use diatomaceous earth (DE-CIDE®)
- 100% natural freshwater diatomaceous earth
- high amorphous silica content (80–90%)
- chemically inert mineral material
- high surface area and porosity
- suitable for bulk agricultural use
- mined and processed in Western Australia
Silica and mineral profile
DE-CIDE® contains naturally occurring:
- amorphous silica (80–90%)
- magnesium
- calcium
- sodium
- iron
This makes it a naturally occurring silica-based mineral source used in agricultural systems.

Related Technical Information
Diatomaceous Earth Science
Diatomaceous earth is a naturally occurring amorphous silica material formed from fossilised diatoms. Its structure is defined by high porosity, large surface area, and unique moisture interaction properties that make it relevant in environmental and material science systems.
It is widely studied for its physical behaviour in dry particulate systems, including adsorption, surface interaction, and mineral stability under varying environmental conditions.

Agricultural mineral systems overview
Blending diatomaceous earth (DE) with attapulgite clay creates a complementary mineral system where both materials contribute different but reinforcing physical properties within dry environmental applications.
Diatomaceous earth provides a highly porous amorphous silica structure with a large surface area and strong moisture interaction characteristics. Attapulgite contributes a fibrous clay structure with high adsorption capacity and structural stability under a range of environmental conditions.
When combined, these minerals can improve overall system performance in terms of:
- Moisture management efficiency through combined adsorption pathways
- Surface interaction distribution due to differing particle geometries
- Structural stability in blended mineral systems under dry handling conditions
- Extended functional surface area across mixed particle networks
- Improved handling characteristics in bulk dry mineral applications
- Enhanced consistency in environmental mineral formulations
This synergy is particularly relevant in agricultural, storage, and environmental systems where controlled moisture behaviour and stable mineral performance are required.

Pest management environments (regulated systems)
Certain mineral dusts are studied in integrated pest management (IPM) systems where approved under regulatory frameworks such as APVMA. These applications are part of structured environmental management programs rather than standalone product functions.
