Paltridge Carbon Project 3

Paltridge Carbon Project 3 is a soil carbon sequestration project located approximately 20km south of Bordertown in the Tatiara District of South Australia, near the Victorian border. Registered in August 2022, the project covers a land area of roughly 408 hectares. The site sits within the Limestone Coast region, an area historically renowned as "Tatiara" (Indigenous for "Good Country"), which is heavily utilized for mixed farming, including cereal cropping and livestock grazing.

The project operates under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models (2021) methodology. This method requires landholders to implement new management activities designed to increase the amount of carbon stored in the soil. For this specific project, activities include applying synthetic or non-synthetic fertilizers to address nutrient deficiencies, converting from intensive tillage to reduced or no-tillage practices, retaining crop stubble, and altering grazing intensity to improve soil vegetation cover.

Environmentally, the Bordertown region is characterized by a "medium rainfall" climate, typically receiving between 450mm and 500mm annually. The local soil profile is often described as "duplex," featuring sandy or loamy topsoil over clay subsoil, or shallow soils over a limestone or calcrete base, typical of the Limestone Coast's geology. The Paltridge family, listed as participants, are long-established landholders in the Naracoorte and Tatiara districts, with a history in the region dating back to the late 19th century. The project is managed in partnership with Agriprove, a prominent soil carbon project developer in Australia.
