Roxon Carbon Project

The Roxon Carbon Project is a soil carbon sequestration project located in the Tatiara District of South Australia, approximately 8 kilometers west of the regional center of Bordertown. Registered in July 2024, the project covers a project area of 263 hectares. The Tatiara region, often referred to by its Indigenous meaning "Good Country," is a highly productive agricultural zone known for mixed farming, particularly cropping (wheat, barley, canola) and livestock grazing.

The project operates under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models (2021) methodology. This method credits landholders for increasing soil organic carbon levels through improved land management. The specific activity listed for this project involves applying nutrients (synthetic or non-synthetic fertiliser) to address material soil deficiencies. This aligns with the model often employed by the proponent, AgriProve, which focuses on soil health and biological stimulation to increase pasture biomass and, consequently, sequester carbon in the soil profile.

Environmentally, the location sits within a Mediterranean climate zone characterized by winter-dominant rainfall, averaging between 450mm and 500mm annually. The soils in the Tatiara district are typically diverse, ranging from the fertile, heavy clay loams (Gilgai) that the region is famous for, to sandy loams over clay on undulations. These conditions are generally favourable for soil carbon projects, provided that rainfall is sufficient to support the increased biomass production required to build soil carbon stocks.
