Roxon Carbon Project

Roxon Carbon Project is a soil carbon sequestration project located in the Tatiara district, approximately 8km west of Bordertown in South Australia. It was registered in July 2024 and covers 263.09 hectares.

The project operates under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models methodology. Soil carbon projects involve adopting new or materially different agricultural land management practices to increase the amount of carbon stored in the soil. The standard requirements involve establishing a historical baseline of soil carbon through strict laboratory measurements, implementing the new management activities, and conducting subsequent sampling and modelling rounds to calculate the net increase in sequestered soil carbon over a permanence period.

The Bordertown and Tatiara region is well known for mixed dryland cropping and extensive livestock grazing operations, principally focused on wool sheep, prime lambs, and beef cattle. The area experiences a moderate climate with typical rainfall averaging between 400mm in the north to 525mm in the south annually. Local soils generally consist of shallow profiles over calcrete and limestone, as well as deep sandy soils over dispersive subsoil clays that can sometimes be prone to acidification and low natural fertility.

This project specifically aims to increase carbon in the soil by applying nutrients to the land in the form of a synthetic or non-synthetic fertiliser to address a material deficiency in the agricultural system. The project is managed by Agriprove Solutions Co No.2 Pty Ltd, which is part of one of Australia's most prominent corporate soil carbon developers. Interestingly, the surrounding Tatiara region features unique local karst environments, where nearby seasonal watercourses like Tatiara Creek naturally flow into "runaway holes" and disappear underground into the unconfined aquifer.
