Natural Fertilisers for Sustainable Agriculture

Improve soil & crop yields while reducing water use & minimising CO2 emissions

Trisil Group is an Australian owned supplier of high-grade Diatomaceous Earth, sourced from freshwater deposits in Lampang, Thailand.

The range of benefits from Trisil’s range are proven to substantially increase agricultural yield from less land with less water, or land that was otherwise non-arable, without causing harm to the environment.

We aim to help revolutionise agriculture by shifting away from chemical products to sustainable practices.

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