Trisil’s goal is to partner with farmers, land owners and government to sustainably and economically improve their land management.

Australian provider of freshwater Diatomaceous Earth to help improve your soil

Scientifically Backed



Higher yields, reduced water usage and less time spent on attending crops results in substantial financial returns.

Soil Health

An unparalleled ability to hold over 150% of its own weight in water, reducing the severity of drought when proactively applied.


Crop Quality

The silicon strengthens plant cell walls allowing crops to withstand common weather stressors including high winds, heat and cold.

Disease & Pest Resistance

The strengthened cell wall provides a reinforced barrier that hinders pests from gaining access to the nutrients within.


The product is non-toxic, increases the rate of carbon sequestration and improves water management practices.

Animal Health

DE reduces levels of mycotoxins in the animal, leading to a higher quality produce such as milk, meat, eggs or wool.

For an upfront cost of say $90, if I'm going to gain even 2t/ha, that is another $500- $550/ha, so you would say I've got a net return off the product of $400/ha after cost. That in itself tells me I'm going to keep using it.

I applied DE to half my cover crop to test the difference. Two months of growth and the difference is unbelievable. Winter crops that tend to get frost affected have minimal damage. Will definitely continue to use DE on all crops.

I made the switch from traditional chemical urea to Trisil’s DE, which resulted in $15/bale profit and 30% less water was used. Coming out of a drought this was an amazing result!

It protects against disease, against sucking and chewing pests. It's really good in saline soils. It will draw up salts and stop salts being available to plants so if you have salty soils you apply that and plants have a chance to grow.

Originally I purchased the powder form to mix with existing fertilser products for crops and saw its incredible moisture holding ability. I now also use it in grain storage to help protect against moisture and weevils, and as a natural, chemical-free pesticide. A diverse product that lasts.
