Anti-caking
DE's porous structure and low bulk density mean a small addition can help maintain free-flowing product through storage and handling. Effectiveness is formulation-dependent and should be validated on your specific product.
Functional role
Where diatomaceous earth contributes
Flowability
Improved flow through hoppers, blenders, baggers and spreaders, reducing bridging and handling losses.
Carrier systems
High absorption capacity allows liquid actives — micronutrients, biostimulants, microbial inoculants — to be carried as a dry, free-flowing powder. Compatibility with the specific active must be established by trial.
Moisture management
Buffering moisture pickup during production, storage and transport.
Granulation support
As a process aid and functional filler in granulation systems.
Controlled-release development
The pore structure offers a route to modified release profiles in specialty formulations. This is a development area we would approach as a joint trial rather than an off-the-shelf answer.

What our customers measure
Additive selection is judged on production outcomes, not on the material specification alone. Improving one of these frequently costs you another — which is why we start from your process data.
- Caking tendency Product condition after storage and transport at ambient humidity
- Flow rate Discharge consistency through hoppers, blenders and bagging lines
- Moisture pickup Weight gain and condition change over storage period
- Additive loading Percentage inclusion required to achieve the target effect
- Granule integrity Dust generation and breakdown during handling
- Cost per tonne Total formulation cost at the required performance
Material science
Silicon as a plant nutrient
Diatomaceous earth is an amorphous silica material, and silicon is increasingly recognised as a beneficial element for silicon-accumulating crops — rice above all. Unlike carbonate-based amendments, applying an amorphous silica material does not release CO₂ on dissolution.
We are careful here. Published silicon research spans a wide range of materials, and results attributed to silicate fertilizers frequently depend on other constituents in those materials rather than on silicon alone. We will share the literature with you and discuss what is and is not established, but we do not publish crop-response figures we have not generated ourselves.
Agronomic response is application-dependent. Field validation is recommended before any commercial claim.
