Newman Carbon Project 4

Newman Carbon Project 4 is a soil carbon sequestration project located approximately 6 to 8 kilometres east of Loxton in the Riverland region of South Australia. It was registered in July 2024 and covers an area of 237.64 ha.

The project operates under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models (2021) method. This methodology allows agricultural projects to earn Australian Carbon Credit Units (ACCUs) by increasing the carbon stored in soil through new or materially different land management activities. Soil carbon increases are calculated using a measurement-only approach or a hybrid approach that combines physical soil sampling with model estimates.

The Loxton region is a major agricultural hub, characterised by extensive dryland farming of cereals, legumes, and pulses, alongside irrigated horticulture such as vineyards, citrus, and almond orchards closer to the Murray River. The environment is semi-arid, experiencing a low annual average rainfall of around 250 to 280 mm. The soil types in the region are highly varied, commonly featuring alkaline sandy loams, deep sandy rises, and shallow calcareous stony soils with underlying clay and mild natural salinity.

Managed by project proponent Agriprove Solutions Co No.2 Pty Ltd, this project is designed to increase soil carbon in the agricultural system by applying nutrients to the land in the form of synthetic or non-synthetic fertilisers to address material deficiencies. Additionally, the project has nominated a permanence period of 25 years, with its crediting period running until July 2049.
